Functions

Switchgear monitoring

SC100 gets internal state of cubicle and displays information on control panel. This information are also available using Modbus communication.

Switchgear operation

The SC100 achieves open or close order on different kind of mechanism: p Lever type (CIT) p Latching type (CI1) p Stored energy type (OCO).

Using motor and coils :

MechanismCIT CI1 OCO

Closing Motor Motor XF coilOpening Motor MX coil MX coilCharging When closing/opening When closing Motor

The orders are taken into account from three different sources: p Control Panel pushbutton p Digital input (B connector) p Modbus communication (SC110 only).

The following table gives the source of order accepted.

(*) The Digital input Communication lock inhibits order from Modbus communication in order to use an external local/remote selector.

Electrical interlock

SC100 takes into account cubicle interlock to prevent operation when not authorized. External interlock can be added, for example, to synchronize with protection relay.

Anti-pumping

SC100 integrates an anti-pumping function which prevents switchgear from open-close-open-close in case of permanent close order and trip condition for example.

Antireflex

Prevents operator from opening a Load Break Switch (LBS) on fault (in case of short circuit established when closing the LBS).

SC100, SC110 - Communication

At a Glance

General

Each SC110 has three communication ports (all connected in parallel).Modbus communication allows SC110 to be connected to a supervisor or any other device with a master Modbus communication port.SC110s are always slaves.S100 products dont support communication feature.

Accessible Data

Modbus communication can be used to perform functions remotely such as: p reading of measurements, counters and diagnosis p reading of status conditions and remote indications p transfer of time-tagged events p reading of SC110 identification p time-setting and synchronization p reading of settings p remote settings when these have been enabled p transmission of remote controls.

Modbus Protocol

Protocol Principle

The Modbus protocol is used to exchange data by means of a request-response type mechanism between one station called the master and N slaves. Exchange initialization (sending the request) is always initiated by the master. The slave (SC110) can only respond to a request sent to it. When the network hardware infrastructure allows, several slaves can be connected to the same master. The request contains a slave number (address) to identify which is the destination. This number must be unique. Slaves that are not destinations ignore the request received:The master can also address all slaves using the conventional address 0.

Response

Master

Interrogation

Slaves

This mechanism is called broadcasting. Slaves do not respond to a broadcast message. Only messages that do not require data to be sent back by the slaves can be broadcast:

35NRJED313570EN 07/2013


Multi-Master OperationWhen SC110s are connected by a gateway to a network that allows multiple access (Ethernet, Modbus+, etc.), several masters are likely to address the same SC110 on the same communication port.It is the network designers responsibility to resolve any conflicts that may occur.

Frame StructureEach exchanged frame consists of a maximum of 255 bytes divided as follows (any frame with an error in format, parity, CRC 16, etc. is ignored):

Slave Number Function Code Data or Sub-Function Code Control Word1 byte 1 byte n bytes 2 bytesRequest destination

p 0: broadcast (all) p 1...247 (unique)

Refer to the next section

Request or response data (addresses / bit or word values, number of bits bytes / data words) Sub-function code

CRC 16 (for detection of transmission errors)

The first two fields in the response are usually identical to those in the request.

Modbus Functions SupportedThe SC110 Modbus protocol is a subset of the Modbus RTU protocol:

p Data exchange functions p 1: read n output or internal bits p 2: read n input bits p 3: read n output or internal words p 4: read n input words p 5: write 1 bit p 6: write 1 word p 15: write n bits p 16: write n words

p Communication management functions p 8: read Modbus diagnosis counters p 11: read Modbus event counter p 43 with sub-function 14: read identification p 43 with sub-function 15: read date and time p 43 with sub-function 16: write date and time

p Protocol for managing time-tagged events.Protocol for managing date and time synchronization.

Structure of Exception FramesAn exception frame sent by the destination SC110 for the request consists of the following fields:

Slave Number Exception Function Code Exception Code Control Word1 byte 1 byte 1 byte 2 bytesRequest destination Request function code

+ 128 (80h)Possible codes

p 1: unknown function code p 2: incorrect address p 3: incorrect data p 4: slave not ready

(impossible to process request) p 7: non-acknowledgment

(remote reading)

CRC 16 (for detection of transmission errors)

36 NRJED313570EN 07/2013


Turnaround TimeThe turnaround time Tr is the time between the end of receipt of a request and sending the response:

Request Request

Response

Broadcasting

Tr Tr

NOTE: Tr includes the silence between 2 frames and is usually expressed for a format of 8 bits, odd parity, 1 stop bit, at 9,600 Bauds.The SC110 turnaround time is less than 10 ms.

Synchronizing ExchangesAny character received after a silence lasting more than 3.5 characters is deemed to be the start of a frame.A minimum silence equivalent to 3.5 characters must always be kept between 2 frames. At 38400 bauds, this time of silence is reduced to 1.750 ms.

A slave ignores any frame: p received with a physical error on one or more characters (format, parity error, etc.) p with an invalid CRC 16 p which is not addressed to it.

Modbus Link Diagnosis

To check that the link is operating correctly, the user can refer to: p 1. the link activity LED, on the front panel p 2. the test zone p 3. the Modbus diagnosis counters and the Modbus event counter.

37NRJED313570EN 07/2013


Link Activity LED

The LED is activated by the transmission or reception of frames on the Modbus network.

NOTE: Flashing indicates that there is traffic. It does not mean that the exchanges are valid.

Using the Test Zone

Run a read/write/re-read cycle in the test zone, for example:

Function Frame Sent Frame Expected in ResponseResponseReading 2 words at address 0C00h 01 03 0C00 0002 C75B 01 03 04 0000 0000 FA33Writing a word with the value 1234 at address 0C00h 01 10 0C00 0001 02 1234 6727 01 10 0C00 0001 0299

Reading 1 word at address 0C00h 01 03 0C00 0001 B75A 01 03 02 1234 B539

More information is available in the Test Zone section (see page 42).

Description of Counters

The SC110 manages diagnosis counters CPT1 to CPT8 and the event counter CPT9: p CPT1: number of valid frames of 4 to 255 bytes received, whether the relevant SC110

is the destination or not p CPT2: Number of request or broadcast frames received, with one or other of the following errors:

p CRC error (but with a correct frame length) for frames addressed to the relevant SC110 or not p incorrect length (< 4 or > 255 bytes) whether the relevant SC110 is the destination or not

p CPT3: number of exception responses generated by the relevant SC110 (except after a broadcast)

p CPT4: number of valid frames received by the relevant SC110 (including during broadcast) p CPT5: number of error-free request frames that have not received a response

(excluding broadcast) p CPT6: not significant p CPT7: not significant p CPT8: number of frames received with at least one character having a physical error

(parity or overrun or framing, break on the line), whether the relevant SC110 is the destination or not

p CPT9: number of requests (except function 11) received by the relevant SC110, valid and correctly executed.

Counter Reset

The counters are reset to 0: p when they reach the maximum value FFFFh (65535) p when they are reset by a Modbus command (function 8, sub-code 000Ah) p during a SC110 power outage.

Using the Counters

The diagnosis counters are read using function 8 and sub-codes 000Bh to 0012h depending on the counter.Function 8 can also be used in echo mode (sub-code 0000h):

Function Frame Sent Frame Expected in Response8 in echo mode 01 08 0000 1234 ED7C 01 08 0000 1234 ED7C

Event counter CPT9 is read using function 11.Even in echo mode, the SC110 recalculates and checks the CRC sent by the master:

p if the CRC received is valid, the SC110 replies p if the CRC received is invalid, the SC110 does not reply.

38 NRJED313570EN 07/2013


Automatic Adaptation of the Configuration: AUTOGO

At a Glance

The Autogo mechanism is a device for simplifying the Modbus device configuration. Its algorithm allows a SC110 (slave) to automatically detect the configuration used on the Modbus bus to which it is connected.

Operation

The algorithm in the Autogo mechanism automatically detects the network parameters by testing the available transmission speeds and parities. The Modbus master must send at least 13 frames on the Modbus network before the Autogo mechanism algorithm works. There must be enough traffic on the bus before the SC110 can be deemed to be absent or faulty.

The detected network parameters are deemed to be valid after correct reception of three different frames. In this case, the product will use the detected parameters and will save them in non-volatile memory.

NOTE: If the Modbus configuration set on the SC110 is modified manually by the installer, the Autogo mechanism will be reset and will revert to the find configuration state.

NOTE: On restarting the SC110, the saved Modbus parameters on the product will be revalidated.

In the event of a fault on restarting, the search phase will be repeated after receipt of 7 invalid frames. Subsequently, the search phase is not repeated if a fault occurs during operation.

NOTE: In the event of a problem in establishing communication, it is advisable to follow the procedure below:

p 1. send the SC110 a Read multiple registers (FC03) from 1 register request to any address p 2. send this request at least 20 times p 3. if there is still no answer, check the Modbus diagnosis LED, wiring, polarization and line

terminations.

Moreover it is possible to disable the Autogo mechanism and then manually set the Modbus network parameters.

Detectable Configurations

The 3 configurations supported by the algorithm are as follows: p Even parity, 1 stop bit p Odd parity, 1 stop bit p no parity, 2 stop bits.

associated with the following 4 transmission speeds: p 4,800 Baud p 9,600 Baud p 19,200 Baud p 38,400 Baud.

i.e. a total of 12 detectable configurations.

Access to Data

Addressing a Word

All SC110 data that can be accessed by Modbus communication is organized into 16-bit words. Each word is identified by its address, coded on 16 bits, i.e. from 0 to 65535 (FFFFh).In the rest of the document, all addresses are expressed in hexadecimal format.

Addressing a Bit

Some data can also be accessed in the form of a bit.The bit address is then deducted from the word address by: Bit address = (word address x 16) + bit number (0...15)

Example p address word 0C00h p bit 0 address = C000h p bit 14 address = C00Eh

Undefined Addresses

Only addresses defined in this document should be used. If other addresses are used, the SC110 can either respond with an exception message, or provide non-significant data.

Access Modes

The data are direct-access: they are permanently identified by their Modbus address. These can be reached in a single read or write operation, applying to all or part of the relevant zone.In SC110, all zones are accessed directly, however for some zones, such as those for time-tagged events, a particular protocol can be used to optimize exchanges with the supervisor. This protocol is specified in the relevant zones.

List of Address Zones

Similar data in terms of control and monitoring applications or their coding are grouped into adjacent address zones:

Data Coding

Formats Used

Apart from exceptions mentioned in the text, SC110 data is coded in one of the formats below: p 32S: signed value, coded on 32 bits p 16S: signed value, coded on 16 bits p B: bit or set of bits p ASCII nc: string of n characters in ASCII code p IEC: time coding format on 4 words conforming to IEC 60870-5-4.

32S Format

In 32S format, the first word is the most significant.An incalculable value, whether invalid or outside the authorized range, is fixed at 80000000h.

ExampleAn I1 current of 10,000 A is coded with a resolution of 0.1 A, and is therefore represented by the value 100,000 or 000186A0h, i.e.:

p at address 0440h: 0001h p at address 0441h: 86A0h.

16S Format

An incalculable value, whether invalid or outside the authorized range, is fixed at 8000h.

ASCII Format

ASCII format is used to code the identification strings for a SC110.

When the ASCII strings do not fill up the field entirely, they are completed with null bytes.

The first character occupies the most significant byte on the first word, the second the least significant byte on the first word, etc.

ExampleSC110 A is coded as follows:

Word Most Significant Byte Least Significant ByteCharacter Hexadecimal Value Character Hexadecimal Value

1 S 53 C 432 1 31 1 313 0 30 SP 204 A 41 NUL 00

IEC Format

The date and time are coded on 4 words, in IEC 60870-5-4 format (bits at 0 in the table are not used: they are always read at 0 and ignored in write mode):

Bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

NOTE: A single remote control order changing to zero does not generate time-tagged events.

43NRJED313570EN 07/2013


Double Remote Control Order Words

The remote control order assigned to each pair of bits in the remote control words (address 00F6h) and remote control selection words (address 00FAh) is predefined:

Bit Remote Control Word Bit AddressSelection Word Bit Address Remote Control Order

Double remote control orders are coded on 2 bits with the following possible values (most significant bit/least significant bit):

p 0/1 for Tripping via the communication, Lock SpringCharge, Simulated Open p 1/0 for Closing via the communication, Unlock SpringCharge, Simulated Close.

NOTE: Value 1/1 is prohibited.NOTE: A double remote control order changing to zero does not generate time-tagged events.

Direct Mode

If remote control orders are configured in direct mode, the remote control order is executed immediately on writing to the remote control word. Resetting is performed by the control logic after the remote control order has been taken into account.

Confirmed SBO Mode

The remote control order is executed in two steps: p 1. selection by the supervisor of the command to be sent by writing the bit in the remote control

selection word and checking the selection if necessary by re-reading this word. p 2. execution of the command to be sent by writing the bit in the remote control word.

NOTE: When this mode is selected, it applies to all control orders.

The remote control order is executed if the remote control selection word bit and the associated remote control word bit are set, both word bits are reset by the control logic after the remote control order has been taken into account. Deselection of the selection word bit occurs:

p if the supervisor deselects it by writing in the selection word p if the supervisor selects (writes) a different bit from that already selected p if the supervisor sets a bit in the remote control word that does not correspond to that selected

(in this case no remote control order will be executed) p if the corresponding order is not sent within a period of 30 seconds.

Time-Tagged Events

Introduction

The SC110 includes a time-tagged event mechanism so that its operation can be monitored using a supervisor. This mechanism is common to several products in Schneider Electrics ranges.This data can be retrieved via the Modbus link. This data is volatile and will therefore be lost if the product is de-energized.

Event Types

A logic event is the change of state of a SC110 logic variable (bit in control, status or remote indication words).An analog event is the record of a tripping current. Each event is mainly characterized by:

p an address: that belonging to the associated bit or word (depending on the type) p a value (for logic events, it is the direction of change) p a date and time: the event is time-tagged (resolution: 1 ms).

NOTE: By extension, an event also designates all the characteristics of the change in state.

Time-Tagging

Time-tagging of events uses the SC110 internal clock. When an event is detected, the SC110s current time is associated with it.

The clock accuracy depends mainly on the quality of synchronization of the SC110 internal clock.

The presence of a valid clock on SC110 is not guaranteed throughout product operation. In fact, during the initialization phase, the clock will not be accessible; it will only become so once the product has booted up fully.

In the event of loss of the clock, detected events will be time-tagged with a default date until the clock is reset. This default date starts on 1st January 2000 00h 00min 0sec.

The chronology of detected events remains valid in all cases.

Description of How to Code an Event

An event is coded according to the invariant TI086.

NOTE: p Event numbering starts at no. 1 and ends with no. 65535. When event no. 65535 is detected,

the next event numbering restarts at no. 1. p Only one type of data is carried in the events of SC110: the Boolean.

The events are always primary type (no associated secondary events) p The event address always corresponds to a Modbus register defined on the SC110.

Event Tables

The SC110 manages an internal storage table with a capacity of 100 events. Upstream of the table, 2 words contain:

p the current number of events present in the queue (between 0 and 100) p the number of the last detected event.

Both these words and the number of the first event in the table form a header that will be used by the supervisor to detect presence of new events.

47NRJED313570EN 07/2013


The table can be seen as a FIFO type stack.

E000h Actual_Number_Of_Events_In_TableE001h Most_Recent_Event_NumberE002h to E4B1h Events_Table (Depth = 100 events), with

p Top_Event in [E002h to E00Dh] p p Bottom_Event in [E4A6h to E4B1h]

NOTE: Reading the events table is not destructive. An event no. x will only be removed from the table if 100 new events have been detected (in other words, event no. x+100 has been detected).

Initializing the Events Table

On starting, the SC110 initializes its events table by filling all the registers (table and header) with the value 0 (no event recorded).

When it starts, the SC110 always adds three events: p initialization in progress p date/time incorrect (not configured since startup) p not synchronized.

These three events are destined for the supervisor for time synchronization and detection of product resetting.

Read Sequence

The consultation protocol for time-tagged events includes a standard sequence that can be executed by a supervisor to detect and retrieve new events present on the SC110. This sequence is divided into two parts:

p detection of new events on the SC110 p reading of new events on the SC110.

Detection of new events on the SC110

New events are detected by periodic reading of the header in the time-tagged events zone (addresses E000h to E002h).If the number of last event in table changes between two header readings, one or more events have been added to the table. The supervisor can then read the new events.

Reading of new events on the SC110

On the basis of values read in the headers, the supervisor can determine the Modbus register ranges to be read to obtain the new event data.

The supervisor determines the position (index) in the table of the first and last new event starting from the event number stored at index 0 of the table.

The Modbus register addresses associated with the new events can be deduced from the indexes: p event start address = E002h + index * 12 p event end address = E002h + (index + 1) * 12 - 1.

Loss of Events

If the number of new events exceeds the table capacity, only the 100 most recent events will still be accessible. The oldest events will be lost forever.The supervisor is responsible for retrieving events from the SC110. It is up to him to adapt his consultation strategy to avoid the loss of events.

List of Possible Events

The SC110 has 50 sources of time-tagged events whose descriptions appear below. Boolean events:

Date and Time-Setting and Synchronization

Introduction

The SC110 manages the date and time internally. If the auxiliary power supply fails, the date & time are lost.

The SC110 internal time is used, in particular, to date alarms and events.

The SC110 also delivers a SC110 time incorrect data item (bit 04) to the control word, indicating the need to set the time.

Time and Date-Setting

p by writing, in a single block, the new date and time value in the synchronization zone (Modbus time frame)

p by using function 43 with sub-function 16.

Synchronization

The time frame is used both for setting the time and synchronizing the SC110 in this case, it should be transmitted regularly at close intervals (10 to 60 seconds) to obtain a synchronous time. It is usually transmitted by broadcasting (slave number = 0).

In synchronous state, the absence of receipt of a time frame for more than 200 seconds causes a loss of synchronism (bit 05 of the control word at 1).

On receipt of the date and time, the SC110 saves the new date. It also checks whether the difference between this new date and the current date is more than 100 ms. If so, the SC110 changes to non- synchronous state (bit 05 of the control word at 1). It will return to synchronous state (bit 05 of the control word at 0) as soon as the time difference between the new date it has received and the current date is less than 100 ms.

Synchronization Cycle

Each synchronization cycle is executed as follows: p 1. the supervisor writes its date and time value in the synchronization zone or by function 43-16 p 2. the SC110 changes to non-synchronous state (bit 05 of the control word at 1)

and resets its clock p 3. if the reset amplitude is less than 100 ms, the SC110 changes back to synchronous state.

Time-Tagged Events Generated

When the SC110 is energized, it generates the following events in succession: p Appearance of SC110 time incorrect p Appearance of SC110 not synchronous.

When the first synchronization message is broadcast by the supervisor, the SC110 generates the following events in succession:

p Disappearance of SC110 time incorrect p Disappearance of SC110 not synchronous.

After a loss of synchronization, the SC110 generates the following event: p Appearance of SC110 not synchronous.

After synchronization reappears, the SC110 generates the following event: p Disappearance of SC110 not synchronous.

51NRJED313570EN 07/2013


Clock Accuracy

The clock accuracy is linked to the master and its control of the time frame transmission delay on the communication network.

Before sending a time frame, the supervisor must ensure that all the read requests sent have received a response. Synchronization of the SC110 is performed immediately after the frame is received.

For optimum synchronization, the supervisor must compensate for the frame transmission time.

The frame transmission time is compensated by the SC110.

If the frames pass through a gateway (multi-master operation), make sure that this does not slow down the frames.

Managing the Date and Time Using Function 43

Introduction

Access to and setting the date and time on SC110 is also possible via two sub-functions of the Modbus 43 function.

These two sub-functions will be referred to as function 43-15 and function 43-16 hereafter.

Read SC110 Identification

Introduction

The Read Device Identification function can be used for standard access to the information required for unambiguous identification of a device.

SC110 processes the read identification function (conformity level: 83h). For a complete description of the function, refer to the www.modbus.org website. The description below is a subset of the function options, adapted to the example of SC110.

SC110 Identification

SC110 identification consists of strings of ASCII characters called objects. SC110 objects are divided into three groups:
