METER PROGRAM Meter programming consists in writing a parameters set that will govern meter

operation in its memory. The meter-operating program can be logically divided in the

following sections:

1. Time program

It is the time program, which establishes the meter operation referring to TOU metered

energy. The meter has 4 tariff energy registers (4 tariffs). The current tariff register is

established as function of the following elements:

1.1 Type of day: There can be defined 8 such types of day. There can be defined up to 12

tariff-switching rules for each type of day (with reference to the 4 possible tariffs), the

switching being made with a resolution of 30 minutes (at hh:00 or hh: 30).

1.2. Type of week: There can be defined up to 8 types of weeks, so that each week day

(SMTWTFS) is allotted a certain type of day.

1.3 Season: There can be defined up to 12 calendar seasons characterized by the

beginning calendar date (day, month). Each season is allotted a certain type of week.

5

2. Special dates

As compared to the usual time program, there can be defined up to 24 days as exceptions

from the tariff program. Each day is characterized by the date and month. In case of non-

repetitive annual dates, the year shall also be specified. Each day is associated a type of

day out of the 8 possible ones and the number of days for which the rule is valid.

3. Summer-winter hour changing rule

The meter uses the European algorithm for the hour change (the last Sunday in March,

and October, respectively). The changing direction and the changing hour shall be

specified. The change of the summer hour in winter can be invalidated.

4. Other parameters

The following quantities are grouped:

4.1The communication speed according to IEC1107, to be selected out of 300, 600, 1200,

2400, 4800, 9600 string of values. Anyway the meter can be forced to communicate at a

speed different from the programmed one.

4.2 Self-reading date. One of the following dates can be chosen: 1…28

4.3 Number of the displayed decimal figures (2 or 3)

4.4 Display hold time for every displayed item (1…60) seconds.

4.5 Meter account: 16 decimal figures

4.6 Program identifier: 8 decimal figures

5.Display sequence

The meter display sequence can be displayed out of a maximum set of available

quantities.

The program has certain syntax as concerns the programming lines, as shown in the table

below:

The program files properly edited or read from the meter bear pmsp extension. Their

implicit location is <Director instalare Opticom 2K>\EnerluxM Files\ Program\. The

programs editing and writing operations are carried out by means of a properties sheet.

Any time this sheet is activated to create a new file, its contents will be that of a self-

created program file named template.pexm. Since this file is a self-created one during

the program running, do not save your own programs in this file.

Operating program creating, editing and writing

Operating program creating, editing writing is carried out by means of PROGRAM

property sheet.

The property sheet contains the following property pages:

Daylight saving time rule

Other parameters

Display sequence Pressing Exit button will close the property sheet. In case the user has made changes in

the currently loaded program, when pressing the button he will be warned concerning the

possibility of loosing those changes. The property sheet quitting is not possible during the

communication process.

Program preview

This page enables the program files loading and saving, the currently loaded program

view, the specification of the target meter parameters (address and password) as

compared to the current meters list, the specification of what is going to be written in the

meter, as well as the communication process start and control. This page is always

present.

The list control shows the contents of the current program loaded for editing and/or

writing. Description column shows the significance of the program line, as per the

syntax, and Explain column contains a brief explanation of the program line. The non-

defined program lines bear NULL value.

Load button enables loading another program file then the current one by means of Open

standard box. If the user has made changes in the previously loaded file, he will be

warned concerning the loss of those changes.

Save button enables saving the current file loaded by means of Save As standard box.

Meter group contains the data of the current meters list, as well as General option

referring to a generic meter, which is not contained in the meters list. In case there is no

current list, only General option is present. Description combo box contains the

descriptions of all the meters in the meters list established in Opticom2K program. The

selection of the target meter is made from this combo box. If All meters check box is

selected, the programming operation will be successively applied to all the meters on the

list. If the current list is null, the combo box is invalidated. This communication option

shall be used when the meters are connected to a communication bus. Serial no and

Password editing fields reflect the contents of the current list as compared to the meter

serial no (used as communication address) and password. As far as General option is

concerned, these fields contain General series and NULL password, or that established in

the reading dialogs behaviour. The alteration of these fields is operational only during the

existence of PROGRAM properties sheet, it not being reflected by the contents of the

list used by the program.

Communication section enables the start and control of the communication operation.

The user may choose writing for TOU Program, Exclusion dates, Daylight saving

time, Display sequence, Parameters, either separately or together. The option is

expressed by selecting the requested check box. It is also permitted to alter only one of

the following parameters: the change of the summer-winter hour rule, the baud speed, or

the number of decimals displayed for monetary units. This can be done by selecting the

requested parameter from the program list and by activating Selection. Selection option

is not active for the display sequence. The use can chose to erase battery functioning

time counter together with the meter parameterisation operation. This can be

accomplished by checking the corresponding checkbox. The option is carried out only for

meters with embedded software version starting with 2.2. The communication operation

begins by pressing Start button. The communication process can be followed in WR

(number of transmitted characters) and RD (number of the read characters) fields. The

process can be stopped by pressing the Stop button. If an error appears during the

communication process, the process ends, and the user is warned by message about the

error. The properties page cannot be changed, and PROGRAM property sheet cannot be

closed during the process.

maximum 12 seasons. The lines that are not complete will not be taken into account.

10

Exclusion dates

There can be programmed up to 25 special data characterized by date (day and month). If

the day is not repeated the next year, the year shall also be repeated (two digits). If the

day is repeated the next year, the year shall be marked with “XX”. Each special day is

attached a certain type of day. A special date is taken into account only if all the boxes

are filled in. The whole table can be deleted by pressing Delete table button.

11

Daylight saving time

The meter observes the European algorithm for the summer and winter hour changing

(the last Sunday in March, and the last Sunday in October). The March switching hour

and switching direction can be programmed (then the October switching will take place

in the opposite direction). There can also be selected Disable daylight saving rule

option.

Other parameters

12

This properties sheet contains certain programmable parameters, namely:

FLAG Baud rate as it is defined in IEC1107, C mode. This speed can be ignored

by the program, which forces the communication at other speed as compared to the

programmed one.

Billing date, which is a monthly parameter and can be established between 1…28

day of every month.

Digits after the decimal point: The metered quantities can be displayed with 0 up

to 3 figures after the decimal point.

Display hold time: The time of displaying a quantity during the display sequence

can be programmed between 1...60 seconds.

Account and Identifier: Two programmable numerical strings of 16 and 8 figures,

which can be displayed and resituated at the meter reading.

Display sequence

The properties page comprises two lists:

Available items: which comprises all the quantities that can be displayed.

Display list: which comprises the quantities selected for displaying.

Each quantity is preceded by a code of 6 figures. The quantities with the first

three digits equal to zero are “simple” and fill in half of the memory space of the

quantities whose superior half code is different from zero. The memory space available

for the display list is equivalent to 31 simple quantities.

13

In order to add something new to the display list, press Insert item button, or

double click the requested item in the list on the left.

To eliminate a quantity from the display list, press Delete item button, or double

click the requested item in the list on the right.

The display list can be totally deleted by pressing Remove all. If Copy list

button is pressed, the maximum possible number of quantities starting with the first one

from the list of available quantities will be inserted in the display list.

METERS ACCESS Communication with the meters

The communication with the meters is based on IEC1107 protocol C mode provisions.

The type of transmission is asynchronous, half duplex, with the following format for the

communication word: one start byte, 7 data bytes, para parity, one stop byte.

The communication begins with a foreword at 300 baud speed, initiated by the

computer, which comprises meter selection through its address, meter type reading, and

the negotiation of the communication baud speed, and the type of communication (data

reading, program reading, or programming). Then there follows the reading or writing

operation proper.

The meter address is that which is specified in the current list chosen in

Opticom2K program, and it has to correspond to the meter series + the last two digits of

the manufacturing year. The address shall be specified only for the meters connected to

the same communication bus. In case of meters, which are read through the optical port,

the address is not necessary to be specified, and General address can be used. On the

other hand, the addresses of Pxx cu xx=00…39 form are reserved to be used in

conjunction with the multiplexing parallel interface. They shall not be used if this

interface is not present at the previously selected parallel port of the computer.

The communication speed is proposed by the meter, correlated with the

previously programmed one. The communication may continue either with this speed, or

there can be forced another communication speed.

The data-reading mode requires only the knowledge of the communication

protocol. The program-reading mode requires the fulfilment of an automatic safety

algorithm ensured by the program. The programming mode requires the knowledge of the

password previously written in the meter. If no password has been previously

programmed, the specified password shall be void (equivalent also to NULL password).

Certain reading or programming functions are available only when the meter

operates in a special mode, namely the CALIBRATION MODE. This mode is operative

only if a hardware modification is made in the meter after its unsealing.

EnerluxM module accepts only ENERLUX M type meters. The access of any

other type of device, even under the conditions of observing IEC1107 requirements will

be signalled out as error.

Meters reading The meters reading function refers to the following possibilities:

Reading of the data as supplied by the meter.

Reading of the meter-operating program as it has been previously programmed.

Reading of the meter status data (i.e. clock, display mode, operating mode).

14

Reading of a complete report concerning the contents of the meter memory, which

sums up all the types of the previous readings.

Following the successful reading operations, the read data will be stored in files of

MeterSerial@aallzzhhmmss type names and extensions of dexm, pexm, sexm type, rexm,

respectively (as concerns the program files, @aallzzhhmmss does not appear). Following

every successful reading operation, the corresponding file will be automatically loaded in

Opticom 2K program view zone.

The reading of the meter program and meter status is made by using a safety algorithm,

while the data reading is possible only on the basis of the data reading procedure

according to IEC1107, C mode.

All the reading operations take place by means of Read meter dialog box.

This dialog box appears after launching any of the reading controls.

If Exit button is pressed, the dialog box closes.


referring to a generic meter, which is not contained in the meters list. In case there is no

current list, only General option is present. Description combo box contains the

descriptions of all the meters in the meters list established in Opticom2K program. The

selection of the target meter is made from this combo box. If All meters check box is

selected, the programming operation will be successively applied to all the meters on the

list. If the current list is null, the combo box is invalidated. This communication option

shall be used only when the meters are connected to a communication bus. Serial no editing field reflects the contents of the current list as compared to the meter series (used

as communication address). As far as General option is concerned, it contains General

series. The alteration of this field is operative only during the existence of the dialog box,

it not being reflected by the contents of the meters list used by the program. Start

automatically check box will start the communication process if checked at the same

time with the dialog box launching, and Close when communication ends combo box

will automatically close the dialog box if checked in case there were no errors in the

communication process. The status of these boxes is memorized in dlgs.cfg. file. The user

may change the status of these boxes during the communication process.

Communication section enables the release and the control of the communication

operation. The communication operation is released by pressing Start button. The

communication process can be watched in WR (no. of transmitted characters) and RD

15

(number of read characters) fields. Pressing Stop button can interrupt the communication

process. If an error appears during the communication process, the process ends and the

user is warned through an error message. The Only current values option, when

checked causes the reading only for current register values (energies and maximum

demand). The dialog box cannot be closed during the communication process.

Reading dialog behaviour

The dialog box enables the configuration of the meter reading dialog boxes through the

selection of the following options: Starts automatically and Close when

communication ends. Default password editing field enables password configuration

for "General" options, as well as quick programming. The user can define new subfolders

for dta and report reading or use existing ones.

Meters programming Meters programming operation implies knowing the password, which has been

previously entered into the meter (if it exists). The programming operation leads to the

change of the meter-operating mode. The programming refers to the following

operations:

Meter internal clock programming

Operating program writing

Maximum demand reset

Special commands:

Display mode programming

Passwords programming

Optical port LED behaviour programming

Meter initialisation

Meter measuring scheme

Meter internal clock programming The control can be operated only if a communication port has been previously

selected for the optical probe, and the current is permitted to program the meter clock.

16

The meter internal clock programming is carried out by means of Program meter clock

dialog box.


Meter group contains the data of the current meters list, as well as General option which

refers to a generic meter not contained in the meters list. In case there is no current list,

only General option is present. Description combo box contains the descriptions of all

the meters from the meters list chosen from Opticom 2K software. The target meter

selection is made from this combo list. If All meters check box is selected, the

programming operation will be successively applied to all the meters on the list. If the

current list is null, the combo box is invalidated. This communication option has to be

used only when the meters are connected to a communication bus. Serial no and

Password editing fields reflect the contents of the current list concerning the meter series

(used as communication address) and the meter password. As far as General option is

concerned, these fields contain General series and NULL password, or the password

established in the reading dialogs behaviour. The alteration of these fields operates only

during the dialog box display, it not being contained in the meters list used by the

program, as well.

Date an time section comprises the following controls:

A time control (date and hour) which enables establishing the date and hour, which will

be written in the meter. Date and hour establishing is carried out by means of up and

down arrows.

Synchronization button: Following the current hour modification, this button is pressed

to update the time control values.

Communication section enables the release and control of the communication operation.

The communication operation is released by pressing Start button. The communication

process can be watched up in WR fields (no. of transmitted characters) and RD (no. of

read characters). The process can be interrupted by pressing Stop button. If an error

occurs during the communication process, the process ends, and the user is warned by

error message. The dialog box cannot be closed during the communication process.

Operating program

17

The operating program writing is carried out by means of Program properties

sheet, Program preview properties page. The operating program writing means writing

into the meter the tariff program and the other parameters, either cumulatively or

selectively.

PROGRAM property sheet can be accessed by means of the meter editing and

programming controls.

Quick programming (meter program, clock)

The command for quick programming enables the transmission to the meter of the

program file loaded in the main window view zone in Opticom 2K program.

The quick clock control enables sending the calculator clock current value to the meter.

If these controls are activated, similar functions dialog boxes will be displayed. If the

operation has been correctly carried out, the communication starts automatically and the

dialog box closes automatically. The communication process can be watched up in WR

(no. of transmitted characters) and RD (no. of read characters) fields. The process can be

stopped by pressing Stop button. The process also stops at the occurrence of an error, and

it can be resumed by pressing Start button, or it can be closed by pressing Exit button.

The password that will be used in the communication process will be that which is

specified at the configuration of the communication dialog boxes.

Meter calibration

Meter calibration implies first of all its proper calibration as concerns the hardware

option. Calibration implies determining a set of four coefficients through calculations

made with the values shown by the meter as compared to the values of the voltages and

currents generator to which the meter is connected. Measurements shall be made after the

measuring circuit has been calibrated. Three measuring points are required for the

coefficients determining:

1. The meter base current for determining the energy pulses division coefficient as

compared to the selected CFDIV meter constant and to the APGAIN measured power

gain coefficient.

2. The minimum current for determining the offset coefficient of the measured power -

APOS.

3. The base and phase displacement current between voltage and 60 degrees current for

determining the displacement coefficient - PHCAL.

The meter calibration is carried out by means of an wizard type dialog. The wizard

comprises the following pages:
