1. OVERVIEW

The 2‐WIRE Web WS.500 offers a lot of opportunities to make logging and visualization of data

possible. What type of data, there may be all kinds:

Measurement of electrical loads: voltage, current, power, reactive power, power factor,

consumption.

Thermostat values: pre‐set (heating, cooling, ventilation), set point, room temperature, fan

speed.

Air sensor values: temperature, humidity, CO2, VOC.

Counting impulses from energy meters such as gas, electricity and water meter.

Measuring energy consumption on devices with fix power on a time basis. (Ex. water heater,

heating oil burners, lights ...)

Alerts to mailbox when crossing power consumption, temperature control

On the web pages to view all log values of the modules in graphs, per hour, per day or per year,

together with the costs of that year.

Also subtotals are calculated, which can be imported into different formats.

Features WS.500:

DIN rail module (2 modules wide)

Power supply: 15V / 1A

Bus connection: 2‐WIRE (up to 500mA) and MODBUS (up to 32 modules.)

Ethernet connectivity with integrated transformers

Network processor 10 / 100Mbit / sec

Real Time Clock with backup battery, daily put in sync with NTP server

Flash Memory 8Mb

4Gb SD card (backup configuration data and logs 3 years)

Upgrading via FTP server 2‐WIRE

64 log channels, each up to five readings (32bits) and 2 consumption values (import‐

export)

Communication every minute to the connected modules for reading the measurements

Logging every minute to SD of five measurements per channel, and every 5 mins 2

consumption values

Energy consumption cost calculation (estimate NOT FOR CLEARANCE !!)

EPC level calculation (kWh / m2)

Web HTML: 4 + 1 user administrator can simultaneously use the server.

set login, password and language (NL‐FR‐EN‐DU) per user.

IP address fix or dynamically via DHCP server

Domain name instead of IP address via DNS server

Full configuration of all modules, create groups for layout


3

FTP client: Setting rhythm for logging data to remote FTP server separately adjustable for

real‐time measurement (interval per minute to 60 minutes) and for consumption

measurements (interval by 5min until 24h). The format is CSV delimited '|', but can also

be the AMR format MMR (BE: EANDIS). Each file has a unique name and can be

incorporated into your own remote database.

HTTP request: Via an instruction request all readings and consumptions per channel from

a selected time and a certain period of time (1 day to 31 days). The format is also JSON

and can be split easily (ex. Excel).

Online control or request statuses ex. relay outputs, thermostat can also be controlled

via an HTTP request.

2. BUS STRUCTURE

The WS500 has two bus systems on board: a 2wire bus according to the 2‐WIRE protocol, and a

3‐ or 4 wire bus according to the RS485 MODBUS standard

PC.080: 2‐wire: BUSTERMINAL 1 (GND) and BUSTERMINAL 4 (VDD)

EMM630 ‐ ACQ.CO2 – TFC.01: BUSTERMINAL 2(A) and BUSTERMINAL 3 (B)

EMM120‐EMM220: BUSTERMINAL 1(GND), BUSTERMINAL 2(A) and BUSTERMINAL 3 (B)

EC.441: BUSTERMINAL 1(GND), BUSTERMINAL 2(A), BUSTERMINAL 3(B) and

BUSTERMINAL 4(VDD)

Between the terminals A‐B there must be placed the provided resistors (120 ohms) at both ends of

the bus!! Recommended is EIB bus cable (4 core)

More information: please consult documentation modules!

3. START UP Connect the included power supply (15V) to the WS500 supply terminals at the top. (Polarity is not

important)

Connect the network cable at the bottom, the WS.500 must be connected to the Internet via switch

or (wireless) router.

Bus connection to the energy modules: EC.441 ‐ PC.080 ‐ EMMxxx etc.

Turn on the power: at the top of the WS.500, all LEDs should light up. After a few seconds LED L2

should turn off, followed by LED L3 and L4 LED. Afterwards led L3 will flash every 2 seconds(heart‐

beat)

L1

S1 S2

L2 L3 L4

POWER

15V


4

Down where the network cable is plugged in, there should light a green LED, and frequently an

orange LED. Then the network is OK.

If EC.441 or PC.080 modules are connected, the power led of these modules should light up.

4. NETWORK SETTINGS By default, the WS500 is configured to "DHCP" which means that at the first boot thee webserver

gets automatically assigned an IP address by your router. To find out the address, there are programs

that show the IP address. You can also download a server‐scanner on the 2‐WIRE website:

ServerScanner:

Start the program and press the green button

so the data appears.

(Sometimes there are more efforts needed)

Now browse to the IP address by typing it in in the

address field and add always the port number!

The default setting is for the port is "8080" For example,

type thus: 192.168.0.220:8080

Note the colon between address and port number!

There should appear the following login screen. If this is not the case, check

the connections again from the web server.

Login with username and password: "adminIP' and password' 2015 '

With this login you can change any IP settings, but not change any password

(this should be done with login 'admin2‐WIRE)


5

HARD RESET to a fixed IP address When there are problems with DHCP (ex. your router has no IP address), and the Server Scanner still cannot find a Web server, despite a decent network connection, you can decide to go to a "default" fixed IP address:

Procedure: Power off the WS500, wait 5 seconds, push button 2 and hold, turn on power, and continue to press until the LED starts to flash. Keep on pushing for another 3 seconds and then release. After about 5 seconds all LEDs are off and the WS500 is now at a fixed IP address. Now you need to "browse" to the default IP address: 192.168.0.123:8080

Note: This address is not always reachable for the network where your PC or laptop is connected to. When you are in a different range, you need to change the network settings of your PC! Further explanations can be found in "TROUBLESHOOTING"

Once logged in:

Click on 'Configuration', then appear the following menus:


6

Starting with 'SETTINGS'. We start with checking the network settings. This is as said standard DHCP.

Do you want to fix the address, or assign a different address or port number, check out "DHCP" and

fill in your address and port number.

Example:

192.168.0.123 and the port number

8080.

Note that if you change this address,

you should write down exactly what is

the new address and port number!

After sending you have no longer

communication and you have to start

the browser with the new IP address

and port number.

Press ‘SEND CONFIG’

After a second confirmation ( in RED) you have to enter in the toolbar of your browser the new

address and port number. If you have communication, the new setting is successful.

Now we have to browse to 192.168.0.123:8080 and then the address successfully setting.

DHCP: automatically assign an IP address via a DHCP server "

Check the 'DHCP' and press' SEND CONFIG.


7

After a short time, a new IP address is assigned to your Web server. (In this example 192.168.0.164:

8080)

Make a note of this new address and press the button to confirm.

As from now there is no communication on your old IP address. Type in the toolbar, the newly

assigned address to recover connection.

Go back to "SETUP" ‐> "SETTINGS"

There has to be Internet available on your web server, otherwise there are no visible graphics, and

you cannot send logs to a remote FTP server.

"GATEWAY": Normally this is the first 3 digits of your IP address, and the last number '1'. (Ex, your IP

address is 192.168.0.123, then the GATEWAY 192.168.0.1)

If you do not fill in this properly, there is no internet possible on your web server.

'SUBNET MASK': default is set to 255.255.255.0

This should only be changed if the Web server is connected to an extensive (sometimes industrial)

network. These settings you will then get notified by your IT technicians.

"DNS SERVER": automatically filled in when you checked on ‘DHCP’. This usually works when you

type in the same IP address as your gateway. (Eg 192.168.0.1)

LOGS TO FTP‐SERVER: It is also possible that you want to send the log data to a remote FTP server. For this we have to work

with an IP address, either with a 'domain'. The port number is always "21" (eg 78.22.222.111:21))


8

IP FTP logserver: Enter the IP address of your FTP log server (port 21 fix)

Do you own a domain name, check the box on ‘IP FTP‐LogServer’

Domain Name: enter the domain name (ex. ‘www.mydomain.com’)

In "SEND FTP CONFIG", if entered a valid domain name, the found IP address will be filled in

automatically (eg 195.130.132.100:21)

Login Name – Pass – Dir Name: In the FTP server, we need (for security reasons) also set a user

password, and optionally a directory where the data is stored.

Multiple web servers can indeed log their data to a single FTP server and then it is desirable that each

logger is assigned a folder for their data.

Of course, the chosen login name, password, and the folder name must also be the same as in the

FTP server. If the FTP server is assigned a folder for each user, the "Dir Name" should remain blank.

The length of the login is up to 32 characters (contiguous without special characters!)

The length of the password up to 22 characters, and the directory maximum 32 characters

RT log : RT stands for Realtime. This is only data from connected modules and shows the actual

recorded values. In function of the type of module: electrical measurements (voltage‐current‐

power‐reactive power ‐ PF), temperature, CO2, humidity, pulse counters ...

Interval adjustable between 1‐15minuten or 'NO'.


9

RT Daylog interval: Once per day, the webserver can send at a chosen time, the complete data

from the previous day, with an interval that can be chosen between 1 and 60minutes.

Send Daylog: time of day to transmit all RT‐logs.

ConsumptionLog: direct forwarding consume to the FTP server at a specified interval.

Day Log Interval: One can also send daily at a chosen time the complete data from the previous

day, with an interval that can be selected between 5 minutes and 24 hours.

Send Daylog: time of day to transmit all consumption logs.

Location Name: All logs are named "Location Name" and get a date stamp. The same “location

name” will also be send with the mails from 'Alerts'. See later

5. MAIL SETTINGS "Alerts for exceeding limits on consumption and temperatures should be set up in the configuration

of the modules . If you have an account with a provider, you can fill in the outgoing mail server

address (eg. Uit.telenet.be) and your email address (sender address).

The alerts can be sent to up to two addresses. (Mail Address1 and 2)

6. UPGRADING: The next compartment is used for upgrading the server and the 2‐WIRE modules. The condition for

this function is of course that the webserver is connected to the Internet.

At 2‐WIRE we have a server where are the necessary upgrade files can be downloaded from. To

check whether upgrading is needed, one can press the button "FIRMWARE VERSIONS"

When the connection with the 2‐WIRE Upgrade Server succeeds, you can see the different firmware

versions available. (Sometimes a second attempt be possible if the server 'occupied'.)


10

"UPG VERSION” means the versions on the 2‐WIRE Upgrade Server.

'INSTALLED VERSION " is the firmware on board the modules in your system.

When UPG version has a higher number than the Installed Version, is to upgrade the

components.

'STYLE SCRIPT " includes the CSS style (= look of the web page), and JavaScript, which is

used to display all the' buttons' function and add the necessary logic.

Upgrading the server deserves more attention! During upload, we see a progress'balk. This is done in

three phases: the first phase is upload the script, the second step is to upload the firmware for the

server, the third phase is to install this firmware. When the progress bar is finished, automatically the

webpage is refreshed and you need to log in again.

When your 2‐WIRE system has modules such as PC.080 or EC.441 there may be an upgrade needed:

If the UPGversion exceeds the Installed Version, you must press the "DOWNLOAD" button. After

some time, there will be green checkmarks beside the available module versions.

(A red cross does not mean available (v255.255.255.255), or failed transfer)


11

The modules are thus not upgraded yet! This should be done in menu 'Modules' ‘MODULES’

At the bottom there are 4 buttons: These serve as a backup of your configuration and logs to SD:

SAVE CONFIG: save configuration to SD (this happens automatically every night at 3 am)

SAVE LOGS: Keep all energy logs to SD (happens automatically every night at 3 am)

LOAD CONFIG: This button can be used if you want to reset the configuration to the last,

last saved copy. (For example, you delete a module, or channels incorrectly filled in).

Keep in mind that if you made a backup yet, this is dated the same day, at 3am!

With this we do not need to re‐enter all data. The password = 'admin2‐WIRE.

Note: The setting of IP address, login and passwords are NOT stored on the SD!

LOAD LOGS: USE ONLY at replacement of the server, same as above!

(The energy logs are thus put back to the last backup (at night at 3am)


12

7. ENERGY PRICES As already mentioned, we can (approximate) calculate the daily energy consumption and there is a

price tag attached to them. When we know what the cost is for gas, water electricity, we can

complete this table below. There are two pricelevels for electricity (day ‐ and night consumption).

Everything must be filled in cents, so DO NOT DECIMAL!!

"SEND" because the values are entered.

NB. Tariff changes you can always change, every day is calculated what your consumption costs was

the inspired fare, and so is stored in the database. Enter your other values in afterwards, this will

have no effect on the previous calculations.

8. LOGIN

The last section in the SETTINGS tops, and is certainly not unimportant:

login ‐ password

LOGIN: The WS.500 can simultaneously work with 4 users. Each user can choose a login name (up to 16 characters), a password (always four digits) and a language version.

Only logged in as administrator, with password "admin 2‐WIRE ' , you can make changes here!

When we start up the first time we see: "USERS": 0

The administrator is not counted in the 4 users, the administrator usually serves only to modify the

configuration so that other users can not make changes. (So do not sprinkle around the admin login

name and password ...) The login name admin2‐WIRE " or ’adminIP’ can never be changed, but you

can change the password (2015).


13

Change password of the administrator:

Type in the filed "LOGIN OLD 'and' PASS OLD ' the current login name (admin2‐WIRE) and password.

Type in "LOGIN NEW 'back' admin2‐WIRE" and "PASS NEW 'your new password (4 digits)

Press 'SENDPASS' to send the new data.

The same applies to newly created users:

Enter to “LOGIN OLD” 'loginold' and “PASS OLD” 1234

At “LOGIN NEW” now the user name (up to 16 characters) and “PASS NEW” password (4 digits)

The 'TIMEOUT' serves to set the expiry time of your login. When there are actions with the web

server this time is restarted every time. If there are no further actions, and the expiration time has

passed, it should be re‐signed.

Adjustable between 1 and 255u. 0 means 30 days’ expiry time.

The language version is a user adjustable and serves for the fixed texts on your web server.

Not all texts have been translated. Some are difficult to translate and are usually displayed in English.

Press 'SENDPASS' to confirm.

When sending the login we always return to the boot menu. We now need to login again to confirm

who you are.

Example:


14

To remove a user is doing it the other way:

At “LOGIN OLD” comes his username, his password at “OLD PASS”.

At “LOGIN NEW” coming now 'loginold' and “PASS NEW “1234

Press 'SENDPASS' to confirm.

NB. From v6.3 can also retrieve the login and password on the next field "USERS" to enter a number

between 1 (user1) and 5 (admin). The data from each user are displayed.

9. MODULE PARAMETERS

Choose the menu 'Modules' Left we see a number of text boxes, and a few notes:

'NEW': entering new Serial

'CHANGE': change the module name (not channel name!) or serial number

'DELETE': Delete selected module

"CANCEL": undo changes if it had not been sent.

'SEND': Forward module to Web server

"DOWNLOAD": back load the previous configuration of the selected

module, provided that the changes had not yet been sent.

"UPGRADE": only active if modules are with 2‐WIRE protocol

To start, we must first complete a "serial number" at the place where we see "Serial No.". The serial number always consists of two figures, one uppercase letter, and returned five digits. These have a meaning:

A = Air quality meter = AQM.CO2

C = Counter module PC.080

D = Dimmer Module (not yet available)

E = Energy meter = EMM.120 ... 630 series

T = Temperature = TFC.01

M = Modbus energy counter EC.441

P = expansie (dummy)module voor EC.441 slimme meter Poort

Serial numbers:

These modules have a fixed serial number assigned by 2‐WIRE and this number

is printed on the module: PC.080, EC.441.

Other modules such EMM.120 ... 630 do not have SerialNr but only a Modbus addresses (range 1‐

247). Still there can only be worked with SerialNrs in programming.


15

Therefore, we will create fictive serial numbers. Most modules require only one channel, except for

the more complex modules such as EMM.630, it has 3 channels required (= 3 phases)

Each serial number:

The first two digits of the serial number will be:

'01' for single phase meters, thermometers, CO2

'03' for three‐phase meters

The meaning of the letter‐character has already been discussed.

The next five digits dialing yourself, but make sure that the serial number "unique" continues!

Examples of the series EMMxxx energy Modbus meters:

Single‐phase (import only): EMM120 ‐ EMM220: 01E00001 ... .01E99999

Single‐phase (import + export): EMM220: 02E00001 … 02E99999

Three‐phase: EMM630 ‐ EMM630CT: 03E00001 ... 03E99999

Thermostat TFC.01: 01T00001 ... 01T99999

AirQuality AQM.CO2: 01A00001 ... .01A99999

The limit on the number of log channels is 64, and the limit of the number of modules is 32.

The first serial number we will enter in the “SerialNr” field. In the field “Module Name "you can enter

a name that refers to the module. (Eg distribution thermostat garage ...) If we press 'NEW' will be

placed typed the serial number in the "list box”.

On the right you will see a module with a number of channels in our serial

(Eg. 01A00001 = 1 Chanel. )

MODE: (meter, thermostat, air conditioning ....) Is selected automatically

UNIT: is automatically filled with "kWh ° C ppm ..."

CH: stands for "CHANNEL" (channel), and is also automatically generated by the Web

server. Channel no, later it will serve to make the link between log channel and

(Modbus) address. (see further).


16

ADDR: Each channel must have a unique address in the range 1‐247. So no channel

can have the same address. Start from number 1 and so on, so that each

measurement input has a unique address. The simplest is to 'ADDR' to complete the

same value as the channel number 'CH'. When we have no serial modules (series

EMMxxxx) we have to program these addresses on these modules via the existing

display on the EMM module itself. (How to change the address on the MODBUS

module is described in the manual of the module itself.)

SUBADD: for PC080 modules and EC441: see manual of these modules.

For the EMMxxxx series:

Serial 01Exxxx: sub add = 0

Serial 02Exxxx: both channels SAME ADDRESS, sub add 0‐1

Serial 03Exxxx: all three channels SAME ADDRESS, sub add = 0, ‐ 1 – 2

PARA3: PARA6: specifically explained in the manual of the module EC441 or PC080.

For EMMxxx should be completed nothing.

Log type: This is for those who want to send the log data to a remote FTP server (see

Section 9).. You can check which log types you want.

NB. The log types are dependent on the type of module, and will always be logged to SD every

minute, even if nothing is checked!

We assume that the EMM modules are on the display assigned a unique MODBUS address. Note

down these addresses and the group or circuit with which this module is connected. Give it a name

(eg lighting above, sockets living room, stove, etc ..)


17

If the Modbus module is connected to the RS485 bus, and there is power to the module, you can

press 'SEND'. In "Module OK" you know that communication, the address and the power supply is in

order. If not, check power, address and bus connection (A and B do not confuse?)

(The address can be checked on the module via the display on the EMM120‐220‐630, see instructions

for the module)

Note: You can enter or modify only one module at a time. Do you want to continue with new

modules, you must first press "SEND" button when it was changed to red light.

If you want to change an existing module, do not type in the SerialNr but select it from the "list box.

A change, if not yet sent can also be cancelled (“CANCEL”) or return to the previous setting by

pressing the "

DOWNLOAD".

When all modules have been introduced and the communication was fine, a brief explanation in case

changes should be made.

A module that you want to change can be done by selecting the serial number in the 'list box:

THEREFORE, DO NOT retype the serial number!

Now you can only make changes in this module. (The other modules are 'locked' to prevent that you

can change anything in the wrong module.)

After changing a text or number, you should always confirm with 'ENTER': Click any other cell, so you

stand outside the cell in which you have made changes. Now, again the "SEND" button will light red.

If any changes are made, click "SEND".

If you forget to give a name to the module, which serves as a 'helping hand', select this serial

number in the 'list box and press' CHANGE'.


18

The text on the button will change to "CONFIRM."

In the box where 'Module Name' is stated, you can

now put in your text. (Vb 'EMM630')

Now press 'Confirm' and you get this name (later)

in addition to the serial number of the module.

Note. The name will be visible only if you leave and

return from the 'Modules' menu.

It is better to give in a module name directly at the

creation of the SerialNrs.

CHANGE SERIAL NUMBER

If you have an existing module which you like to replace by the same type (eg EC441, SN 08M00001)

and you want to keep the existing logs, you can change the serial number on the condition that the

first three digits are the same. (Eg new module has serial 08M00015)

Select the serial number from the old module in the

'list box and press' CHANGE'. The text on the button

will change to "CONFIRM." In the box where the old

"Serial No." state, you can now change the last 5

digits to the new serial no.

Press 'CONFIRM'. A second screen appears for

confirmation again. then press 'SEND'.

If the module is connected correctly, the answer is

"Module OK" will be. In case the module is not yet

connected the answer will be 'Module NOK.

NB. If you still want to start with new logs, and delete all previous logs of this module, you must first

delete the old module (DELETE), and then completely recreate the new module.

10. ALERTS The web server WS500 has a function ALERTS. These are warning messages that are out as an email

when a consumer has exceeded a certain condition. We must clearly state that this function does not

replace an official alarm system!!!

What are the possibilities:

Indication of the status of an input connected to a window‐door contact, motion sensor,

current or voltage sensor.

Warning when power exceeds a limit.


19

Warning when the daily consumption exceeds a limit.

Monitoring temperatures if upper or lower limit is reached.

The WS500 can be filled up with to 2 email addresses, which receive these messages.

For the programming the PC.080 we have to complete a number of parameters according to the

mode.

At the parameter‐field 'ALERT' (= ALARM) we determine the logic that is to be followed:

The maximum number of characters is 5, the first character contains the logic, and the other

characters must be digits from 0 up to 9999. Exceptions are temperatures with lower and upper limit

where we will place a letter between two values (see below)

In function of the chosen MODE we use letters that determine the "logic":

Input contacts: A followed by an on‐delay 0‐9999 sec

Power limit: p (power) for capacity up to 9999 W

Power limit: P for larger capacity up to 9999 kW

daily consumption limit: c (consumption) for consumption up to 9999 Wh

daily consumption limit: C for large consumption up to 9999 kWh

Temperature: see below in Table temperatures

The possibilities per Type explained in a table below:

1. STATUS TRACKING: The alert function is activated by the letter 'A' for input contacts.

FUNCTION: MODE PARA3 ALERT PARA6

Track status of the connected input

Alway’s bi‐stable

Type contact:

Delay ON

Pushbutton with ‘toggle’ function (PB)

Bi‐stable 0 Ex. A10 (10 sec delay)

Ex. 120 (120 sec delay)

Contact normal open (NO)

Bi‐stable 1 Ex. A0 (no delay)

VEx. 5 (5 sec delay)

Contact normal closed (NC)

Bi‐stable 2 Ex. A500 (500 sec delay)

Ex. 0 (no delay)

Example email with warning:

2. POWER LIMIT: The alert function is activated by entering the letter "p" or "P" (power) in the

alert field.


20

When the power of the connected meters exceeds longer than one hour the limit, an email is sent

with the data set limit and measured value.

At midnight, the measurement is restarted for a new evaluation.

FUNCTION: MODE ALERT

Warning high power Always counter

Power Limit (W of kW)

Power up to max 9999 W (Resolution 1 W)

Counter Ex. p1000 (Border 1000 W)

Power up to max 9999 kW (Resolution 1 kW)

Counter Ex. P10 (Border 10 kW)

Example of a received mail:

3. DAILY CONSUMPTION LIMIT: the alert function is activated by the letter "c" or "C"

(consumption). If the daily consumption of connected meters goes above this limit during the

day, an email is sent with the data set limit and measured value.

At midnight, the measurement is restarted. This results in maximum 1 message per day.


Warning 1 day consumption Counter Consumption limit(max 9999 Wh)

Consumption up to max 9999 Wh (resolution 1 Wh)

Counter Ex. c1500 (limit 1500 Wh)

Consumption up to max 9999 kWh (resolution 1 kWh)

Counter Vb. C30 (limit 30 kWh)


21

Example warning day consumption goes above a limit of 15 kWh:

4. TEMPERATURE LIMIT:

Temperatures can be very important, and in some applications you want to follow this closely.

Examples fridge‐freezer monitoring, risk of frost, over‐temperature boiler ...

Therefore, it is also here to introduce a (limited) logic for measuring values of ‐15 ° C to + 85 ° C

Note. All limits can only be full integers, so half a degree is not possible!

There is a fixed delay of 30 minutes before an alert is possible.

If there has been an alert, we can set the waiting time before there will be a new alert possible. In

'PARA6' will be placed this time. The waiting period must be at least 30 minutes, and can go up to

1440 minutes (= 24 hours). 0 means only 1x per day alert.

The options are:

Alert when the temperature drops below the set value

Alert when the temperature is HIGHER than the set value

Alert when the temperature falls below the minimum limit OR HIGHER than the maximum

limit.

Keep in mind that negative temperatures are possible, and ‐15 ° C lower than ‐5 ° C ...

Lowercase letters mean BELOW, uppercase means EXCEED

When a sensor is 'linked' to a different sensor (see page 4), a distinction needs to be made which

sensor we mean, because you cannot set an alert function on the input of the connected sensor

(slave).

Where we have '255' filled in 'ADDR' there cannot be made an alert function. Therefore, we use two

types: "T" (t) is the main sensor and the associated sensor is 'O' (o) (outdoor).

The following table makes it more clear:


Temperature control Thermo t or T = sensor1 (master) o or O = sensor2 (slave)

Temperature LOWER than limit SENSOR 1 (master)

Thermo Ex. t‐5 (temp LOWER than ‐5°C) Ex. t23 (temp LOWER than +23°C)


22

Temperature LOWER than limit SENSOR 2 (slave)

Thermo Ex. o‐10 (temp LOWER than ‐10°C) Ex. o23 (temp LOWER than +23°C)

Temperature HIGHER than limit SENSOR 1 (master)

Thermo Ex. T‐5 (temp HIGHER than ‐5°C) Ex. T23 (temp HIGHER than +23°C)

Temperature HIGHER than limit SENSOR 2 (slave)

Thermo Ex. O‐10 (temp HIGHER than ‐10°C) Ex. O23 (temp HIGHER than +23°C)

Now there is a third possibility: compare BELOW OR ABOVE

Now we have to set in 2 limits, and it must also be possible to set in both negative and positive

temperatures. Only a maximum of five characters are possible. Therefore, we are going to put the

type BETWEEN the two values. The minus sign is NOT used, but is represented by a letter. Please

note: the first value is always the limit for LESS THAN, and the 2nd is the limit for EXCEED. This means

that the first value must always be smaller than the 2nd value!

We therefore only three combinations:

limit negative 1st, 2nd negative (n or N)

1st limit negative, 2 positive (m or M)

1st limit positive, 2nd positive (p or P)

The combination of the 1st and the 2nd positive limit value can never, because then the first value

would be greater than the 2nd negative, and this is not possible.

Following letters are used for these three possibilities, both for sensor1 and sensor2:


Temperature control With lower – and upper limit

Thermo Capital letters = sensor1 (master) Minor letters = sensor2 (slave)

Limit1 negative Limit2 negative SENSOR 1 (master)

Thermo Ex. 10N2 (temp LOWER than ‐10°C OR temp HIGHER than ‐2°C)

Limit1 negative Limit2 positive SENSOR 1 (master)

Thermo Ex. 10M25 (temp LOWER than ‐10°C OR temp HIGHER than +25°C)

Limit1 positive Limit2 positive SENSOR 1 (master)

Thermo Ex. 10P25 (temp LOWER than +10°C OR temp HIGHER than +25°C)

The same can be done if we have an associated sensor (sensor2)

All letters must now be used lowercase.


Limit1 negative Limit2 negative SENSOR 2 (slave)

Thermo Ex. 10n2 (temp LOWER than ‐10°C OR temp HIGHER than ‐2°C)

Limit1 negative Limit2 positive SENSOR 2 (slave)

Thermo Ex. 10m25 (temp LOWER than ‐10°C OR temp HIGHER than +25°C)


23

Limit1 positive Limit2 positive SENSOR 2 (slave)

Thermo Ex. 10p25 (temp LOWER than +10°C OR temp HIGHER than +25°C)

An example of the warning:

A few more tips to make good use of these 'alerts':

To set up the limits of power monitoring or day consumption, you can look in the respective charts

during the week, and take the peak values.

Also look to the average on a weekly or monthly graph, and make your own conclusion: could I

achieve the same comfort with less energy? In what period are these tops in consumption? Too

many "sleep power" by devices in standby mode? Perhaps now you can see who is responsible for

the big waste. A little warning by your email alert tells you that there is (excessive?) too much

consumption, according to your configurations. Do you get constant alerts, adjust the limits, because

it may not start to work disturbing.

Good luck with this 'ALERTS'. This could be the start of your first 'savings' ...

11.LAYOUT Go to the menu CHANNELS. We now see the channel names in the same rank as those we have

created in our modules, but maybe this is not the order you like you see in the dashboard. It is also

interesting to 'group' the consumers.

Left there is a text field 'Group Name'. Furthermore, there are a number of buttons with the

following functions:

'NEW': Naming a group eg heating, lighting, ventilation, automatic head ...

"CHANGE": edit a group name


24

'Delete': Remove group

"SORT" Order To determine the channels for the visualization

'DESCRIPTION': divide the channels into groups

"CANCEL": failure to implement the change

"SEND": forwarding groups to the web server

"DOWNLOAD": return showing previous configuration, provided that the changes were not

sent!

We must always begin with the completion of group names: Go to the field where "Group Name" is

stated and then enter a new group name in there. Press 'NEW'

The name will now appear in the "list box, press 'SEND' will turn red to

indicate that a change is happening, but we also get alert with the

message" RESET GROUPS? ", Press" Cancel "

So we will continue until all the groups have been given a name (max 8).

Now we can sort the channels if the order is not desired, press 'SORT'

Click on the channel text field that you want to move. This name is now coloured red. Then click on

the number field where you want the clicked channel to go to. The desired channel will now appear

in place and it is coloured yellow.

These two steps we repeat until all names in the desired order.


25

Here is an example:

Now we have to divide the channels in the categories:

Press 'DESCRIPTION' and confirm the question "RESET GROUPS" ‐> OK

Now click on each time to the last channel of each group.

Each group is now coloured .... made mistake? No problem, you can always re‐order or delete / or

add new groups.

When everything is in order, then click "SEND".

example:

12. MAIN CHANNELS AND ENERGY VALUE EPC Below the channels there are some specific channels that we can use for the overview of electricity

and heating consumption, water consumption and calculate the EPC level.

example:

When you have an overall measure of your electricity consumption (can also be a 'smart meters'

value), then enter the log‐channel number at the ELECTRA Ph1 field. This channel number will be

found in the table above (LOG_xx ). Do you have a three‐phase system, then you must enter the 3

channel numbers.

Ex. LOG_8 ‐ 9 and 10, the total measurements of phase 1‐phase 2 and stage 3

For the heating this can be gas or petroleum or electricity. If you measure these consumers on the

Web server, then also enter these channels. (The gas meter can also be linked via the smart meter

through the serial P1 connection at the EC.441)

Is there a pulse contact provided for the water meter (via EC.441 or PC.080), please fill out this

channel also.

And if you have solar panels and an energy meter (EMMxxx) connected to it, you can enter up to

three channels (for three‐phase meters)

Finally, we make an (approximate) calculation of the EPC level (energy efficiency value of the

building): This is a value in kWh / m2, which is in function of heat consumption and the area of the

house. The lower the number, the better your home is insulated.

The total consumption of heating is divided by the heated surfaces in the home. The unit is KWh /

m2. At the installation time we do not have logging values for the whole year the webserver then

makes an estimation of the missing time periods as a function of the heating period has already been

measured.


27

If you have an additional heating system such as a stove, or when your regular use additional electric

heating loads, you need to "EXTRA HEATING 'Enter the estimated annual energy consumption: Ex.

Wood produce about 4 kWh / kg

Do you have a temperature sensor connected via the module EC441 or

PC080, and you want to display this temperature on the login screen, you

can enter this channel at 'OUTDOOR_TP'

13. BEDIENING Go to 'EXIT'. The page will reload and you can see the following:

On the left are the group names, and

some menus for visualization of the

logs. On the right we see the

channels in the order as we have

ordered them.

Clicking on a group on the left, closes

any other open groups and opens

the requested group.

Clicking on a group on the right

opens or closes the group.

When there are active and

connected loads, every minute a

measurement is taken.

However, the page will be as you

see them now, the new measured

values shall not show.

Do you want to keep them

constantly in mind, you can click

‘refresh the page’ in your browser. Or press ‘AUTO REFRESH ', and every minute you will now see the

newly measured values.

Each channel now shows the main value’s: consumption, daily consumption, annual consumption.

(Or temperature...CO2 ...)

Note. When a 'graph' is displayed, there is no 'refresh' possible that channel!

The thermostat TFC01 you can do all the settings on your dashboard:

There are three "regimes": "HEAT = heating, 'CLIMATE' = cooling (if there is one), and 'fan' =

ventilate. When the heating system is working with fans, there are three speeds that can be selected,

or "AUTO" = automatic speed adjustment recorded against the temperature difference.


28

At the right is the "set points to its left the" room temperature. " By pressing one of them (room

temperature) you can increase or decrease the set point by half a degree.

Below these temperatures, a red beam (= heat) or a blue beam (= air conditioning on) appears to

indicate present status.

ODERAT

In the AQM.CO2 module we see the room temperature, humidity, CO2 content, and an indication of the air quality (VOC): VERY GOOD ‐ GOOD ‐ MODERATE – POOR

14. GRAPHS CONTROL: Clicking on the name of a consumer in chart shows the daily consumption of that

consumer. To 'hover' over the chart we see a tooltip with the measurements in time.


29

By clicking again on the name the month graph will be displayed

On the right there are two arrows <<< || >>> With these we can go back up to 7 days at the daily

schedule, or up to 12 months at the monthly statement. Click once more closes the chart.

Note. Opening a graphs for the first time may take several seconds (according to the speed of your

browser and laptop / tablet). The next time this will go considerably faster because the graphics are

buffered.

Clicking 'DAY' shows all channels simultaneously see their readings per hour.


30

Clicking 'MONTH' shows all channels simultaneously see with readings per day.

If you have connected temperature sensors, you can see in this chart the minimum and maximum

temperature of the day.

Clicking 'YEAR' shows all channels simultaneously with their readings per month. Just above the top

of the chart shows the consumption and estimated cost per month and the year totals.


31

Click on ‘OVERVIEW' shows in a table an overview of electricity consumption, heating consumption

(gas or oil), water and possibly yield of solar panels. An EPC (energy level) levels approximate

calculation is computed if the parameters are entered as explained in Chapter 11 (LAYOUT)

The "TOP 10 CONSUMERS 'gives an overview (in euros) of the most expensive energy consumers.

Below is a table reading a monthly consumption and projected energy costs. For comparison, you can

see the consumption of last year (if your system has been in service for over a year) The outputs are

sorted according to the largest costs.


32

When you have filled in a canal at 'total electricity (see Chapter 12), then there's now see an extra channel:' VARIA ', this is the difference between the total measurement, and these measurements.

15. EXPORTING SUBTOTALS

It can be useful if you want to calculate consume over a given period, and there is even an (approximate) cost calculation.

To do this click on the menu on the left to "SUBTOTALS”. The following image now emerges.

Click the field next to "START DATE" and you will now see a calendar. Select the start date for the

period. Right on this calendar you can select the starting hour (per quarter).

Do the same for the end date (END DATE)

(Standard it is set to the current time)

Then click on the button "CALCULATE".

The screen will now show all the subtotals of the log channels. (Log channels CO2 or temperature are

not included in this table, only "consumers")

The waiting time for the calculation can vary in function of the period and the number of channels.

(Eg. Period 9 months, with 20 channels can last about 8 seconds)

An example:


33

The table name first, then the consumption of the starting time (START VALUE), the consumption of

the end time (EndValue), the difference between the two (DIFF), the unit (UNITS) and the

(approximate) cost (COST) . This price was calculated according to the values entered in the

"SETTINGS".

In the 'Search' you can type part of a name and then these names are only shown which occur in the

keyword.

On top of the table, there are now several "buttons": this we can export the displayed table with the

filename = 'Subtotals ENERGY jaar_maand‐day‐hour‐minute, "and the extension:EXCEL: ‘.xlsx’

JSON: ‘.json’

CSV: ‘.csv’

PDF: ‘.pdf’

With the button “PRINT”‐ we can directly print out this table.

NB. Exports choices 'EXCEL' 'json' are not supported on many tablets (especially IPAD)

(Full support under Microsoft Windows)

16. LOGGING TOWARDS FTP‐SERVER Do you have your own FTP server? Or do you have one available through your service provider? Then

you can get more out of the 2‐WIRE Web server!

LOGGING:

LOG TYPES: The logs are in CSV format and separator is a “;”. The decimal separator is a “,”. There

are four types of logs available:

RT log: Real Time logs of measured values: voltage, current, power W (), power (VA), Power

Factor (PF), m3, m3 of gas, litres of fuel, temperature, CO2, ...

The interval can be set from 1 minute to 15 minutes. (NO is inactive) When active, the values

of all log‐modules are redirected to the log server following the interval.

You can specify which measurements are to be logged in the setting of each individual log‐

channel by a checkbox! (This occurs in the configuration of the modules)

File Name: LOCATION NAME + Log type + DATE + TIME + .csv

(Ex. Nieuwstraat18Aalst_RTLOG28082015_013003.csv)

RT Daylog (AMR): the webserver can also send all collected Real‐Time day‐logs once per

day. The interval of the measurements can be set here, from 1 minute to 60 minutes. In CSV

format we see all log channels with their associated measurements (as indicated in the

RTlog‐checkbox)

The CSV file has been prepared using the "AMR" format (see EANDIS)

Note: A file containing 32 log‐channels, each measuring about 5 types (V‐A‐W‐VA‐PF) with an


34

interval of one minute takes approximately 1MB in size.

The point in time when the file is transmitted is set per hour.

The logging is starting from midnight to midnight.

File Name: LOCATION NAME + log type + DATE + TIME + .csv

(Ex. Nieuwstraat18Dendermonde_AMR_28082015_0001.csv)

Consumption log: The values can also be logged with intervals of 5 minutes to 60

minutes and will be forwarded directly to the log server. Here one can see the consumption,

split apart according to day and night rate. (if present)

If solar panels may also be displayed separately.


(Ex. Nieuwstraat18Dendermonde_PAYLOG28082015_013003.csv)

Consumption Daylog (MMR): identically as in the RT Daylog, but only consumption,

with an adjustable interval of 5 to 60 minutes, or 1 total log of 24h.

The CSV file has been prepared using the "MMR" format (see EANDIS)

The point in time when the file is transmitted is set per hour.

The logging is starting from midnight to midnight.


(Ex. Nieuwstraat18Dendermonde_MMR_28082015_013003.csv)

LOCATION NAME: This information is the file name, and also featured in the header of the file.

EANnr: can be invoice number, location number ...

17. DATA TRANSMISSION VIA HTTP

Log data retrieval is also available with a very simple HTTP request. Enter a statement in the 'Toolbar' from your browser and the 2‐WIRE Web server will answer with a mass of log data. When you can capture this data and process it in your database, you can create your own graphs, statistics or warnings at over‐consumption ....

The data has the 'JSON' format. The following commands are possible:

Retrieve current (real‐time) measurements (5logtypes) of all log‐channels

Retrieve historical (real‐time) measurements of the previous period (up to 3 years back)

Retrieve consumption‐by‐the‐hour Calling back hourly (up to 3 years back)

Daily consumption and daily energy cost (up to 1 years back)

Interested? Check our website and ask for the HTTP instruction‐set at www. 2‐WIRE.be

18. QUICK START A shortened repeat of all the steps:

5. Make the necessary connections of power, bus, LAN network.


35

6. Retrieve the IP address and port number of your webserver via the “IP Server Scanner”

software.

7. Surf to the address and port number (default 8080)

8. Login with 'adminIP' or ‘admin2‐WIRE’ and password '2015'

9. Change to fix IP address: go back to menu "SETTINGS" (see Chapter 4)

10. Add new: go to menu "SETTINGS" old login = 'loginold' old pass = '1234'

11. Check energy prices: go to menu "SETTINGS", below, cost

12. Add new Modules: go to menu 'Modules' type serial number, assign names, parameters, fill

according to the type of module (see leaflet in this section) and send.

13. Create Channels: to menu CHANNELS ", first create groups (minimum 1), then sort channels,

divide the groups over the channels.

14. Main sources: if there are total measurements for menu CHANNELS 'type of channel

numbers for electricity, gas, water, heating oil.

15. Export of energy: if total measurements are for export (solar panels), to menu CHANNELS ",

typing in the channel number (s).

16. EPC‐level calculation: determine the heating source (s), to menu "CHANNELS", typing of this

log‐channel number (s) and estimated surface area of the heated rooms.

17. Go to 'EXIT' and test all channels. (Attention: logging appears only after the first hour!)

18. PROBLEM SOLUTIONS REFRESH PAGE: When you are on the website of your webserver, and the buttons give no reaction,

then you're probably lost the 'connection'. This may be because your login time has expired, or your

PC / tablet was turned off. If so, then go to the 'tool bar of your browser and refresh the page.

Usually you will have to log in again and then everything will work normally again.

When there are problems such as the message "page not found" or the 'hourglass' continues to run,

then there may be a network problem. Try to reload the page. If this is not successful, check whether

there is Internet connection by visiting a known website.

SEARCH IP‐ADRES: If you are unable to log in, and there's decent network connection, then you may

be using the wrong IP address. To determine this, we need an IP address scanner. This program can

be downloaded via the 2‐WIRE website. (IP Server Scanner). This program will make a 'broadcast' on

your local network to search for your Web server. When the server scanner has connection, you will

be able to read all settings. There may be assigned a different IP address. (DHCP ...) and this is the

way to find out.

NETWORK PROBLEM: If you cannot reach your web page even after checking with the Server

Scanner, please check the network cable: At the bottom of the web server where the network

connector is plugged in, there are two LEDs: green must still lit, the orange LED off and then light up

briefly.

When the orange LED never lights up, the network is not connected to your network.

On top of the WS500 close to the power connector there should light up a green LED, if so then the

power is okay. Right above there are two push‐buttons, with two associated LEDs. Both LEDs must be

off, and every 2 seconds the left side LED should light up briefly (heart beat).


36

If there remains a continuous LED lights up, then something has gone wrong with the network. Turn

the power to the webserver and wait for 5 seconds, and turn back the power. The LED should light

up a 3 seconds and go out afterwards.

DHCP: When there are problems with DHCP (ex. your router has no IP address), and the Server

Scanner still cannot find a Web server, despite a decent network connection, you can decide to move

to a 'default' address:

Procedure: Power off the WS500, wait 5 seconds, push button 2 and hold, turn on power, and

continue to press until the LED starts to flash and keep on pressing another 3 seconds before release.

After about 5 seconds, all LEDs are off and the WS500 is at a fixed address. Now you need to

"browse" to the default IP address: 192.168.0.123:8080

Note: This address is not always suitable for the network where your PC or laptop is connected.

When you are in a different range, you must change the settings of your PC!

CHANGE IP‐ADRES: You can also change the IP address with the Server Scanner.

After the program has found your web server, you can manually change the current IP address with

this program. Type the address and port number, along with other data such SUBNET, GATEWAY,

DNS.

FAULTY JAVASCRIPT/STYLE: If you discover errors on the website, or there is no key that still reacts,

even after 'refresh page, then there may slipped an error when loading the script / style. You can

then manually re‐download the javascript by pressing the 2‐Wire Server button 1 (left, shortest at

the power connector) and keep pressing until the left LED lits continuously. Then release the key.

Now the LED 15 to 20 seconds should stay on and then go out again. If this is OK, then you do the

right button (press 2) just the same: keep pressing until the flashing stops and both LEDs light up

continuously, then release the key.

Now the LEDs must also be 15 to 20 seconds on and then the right LED starts quickly flashing.

Afterwards the LED will burn continuously 3 seconds and then go out. Everything fine !!!

When these things happen as described, then try again "refresh page and sign in.

CLEAR COMPLETE DATABASE, RESET IP and PASSWORD:

Key 1 (shortest to power connector)

Procedure: Power off the WS500, wait 5 seconds, press button 1 and hold, turn on power, and

continue to press until the LED starts flashing, keep pushing another 3seconds until the LED stops

blinking and then release.

The delete process may take about 60 seconds, and the WS500 is ready when the LED goes out.

IFORGOT IP‐ADRES or FORGOT PASSWORD:

Key 2 (far right away from the connector)

Procedure: Power off the WS500, wait 5 seconds, push button 2 and hold, turn on power, and

continue to press until the LED starts to flash. Stay on pushing another 3 seconds until the LED stops

blinking and then release.


37

The delete process can take about 3 seconds, and the WS500 is ready when the LED goes out.

Now you need to "browse" to the default IP address: 192.168.0.123:8080 and login, password as

described in Part 8

In summary:

Pressing buttons during the running:

Key 1: Upgrading Javascript and CSS.

Key 2: Upgrading firmware Webserver WS500

Pressing keys during startup POWER:

Key 1: Delete entire database, IP address, reset, login and password

Key 2: reset the IP address and password.
