4 IEC Presentation 0 PB03454 General IEC enables Sepam units to be connected to a supervisor or other device featuring an IEC channel. Communication is based on the master/slave principle: b Sepam is always a slave station. b The master is the supervisor or another device. IEC is available via the ACE969-2 interface. ACE969TP-2 interface. ACE969-2 is a multiprotocol interface with two independent ports: b The S-LAN (Supervisory-Local Area Network) port is used to connect Sepam to a network dedicated to supervision. b The E-LAN (Engineering-Local Area Network) port is reserved for specific Sepam setup, operating and adjustment functions. This port is connected to the SFT284 software tool. PB03453 The ACE969-2 interface is available in two versions, linked to the physical interface of the S-LAN supervision port: b ACE969TP-2 (Twisted Pair) for an S-LAN network, 2-wire RS 485 serial link b ACE969FO-2 (Fiber Optic) for a fiber-optic star or ring S-LAN The E-LAN engineering port is always a 2-wire RS 485 type port. ACE969FO-2 interface. Accessible data DE805 S-LAN SFT284 Sepam series 20 E-LAN ACE969-2 IEC via the S-LAN port provides access to a great deal of information, in particular: b Reading of metering information b Reading of status conditions and time-tagged events b Transfer of files including disturbance records and for Sepam series 60 and Sepam series 80, tripping contexts out-of-sync context, Motor Start records, Motor Trend records and Data Log records, b Time-setting and synchronization b Transmission of remote controls The actual list depends on the application, the type of Sepam, the enabled functions, and the ACE969-2 interface parameter settings. Sepam series 40 ACE969-2 Sepam series 60/80 Connecting the SFT284 tool to the E-LAN port also provides access to all Sepam function parameters and operating data: b Hardware configuration parameters b Remote settings for protection functions b Switching on/off of protection functions b Retrieval of disturbance records and, for Sepam series 60 and Sepam series 80, Motor Start records, Motor Trend records and Data Log records b Display of metering and diagnosis information b Display of logic states b Display of alarms ACE969-2 Two independent networks: S-LAN: IEC supervision E-LAN: For SFT284 operating functions. 2 SEPED305002EN - 0/203

User process Application layer (Layer 7) Link layer (Layer 2) Physical layer (Layer ) Presentation The IEC protocol is a companion standard for the informative interface of protection equipment. Standard IEC was prepared by IEC technical committee 57 (Power system control and associated s). It is a companion standard for the basic standards in series IEC As a companion standard, it adds semantics to the definitions and functional profiles specified in the basic standards: b Definition of the particular uses for information objects b Definition of specialist information objects b Definition of service procedures or additional parameters in respect of the basic standards Standard IEC defines between protection equipment and devices of a control system (supervisor or RTU) in a substation. Standard IEC can be obtained in full from the International Electrotechnical Commission: SEPED305002EN - 0/203 3

6 IEC IEC protocol 0 Protocol principle General Standard IEC defines a multipoint protocol via which information can be exchanged between a control system (supervisor or RTU) and one or more protection devices. The control system is the master and the protection devices are the slaves. Each slave is identified by a unique address between and 254. Address 255 is reserved for broadcast frames. Standard IEC defines two different methods for exchanging information: b The first is based on the use of predefined data structures (ASDU - Application Service Data Units) and application procedures supporting the transmission of standardized information. b The other uses generic services supporting the transmission of any type of information. Sepam does not use generic services. The protocol distinguishes between: b The Monitoring direction for the transmission of ASDUs sent by a protection device (slave device) to the control system (master device). b The Control direction for ASDUs sent by the control system to a protection device. Monitoring direction Communication is based on the cyclic transmission of link-layer polling requests by the master in order to invite the slave to send its data. b Class data polling is usually used for event transmission. b Class 2 data polling is used for the cyclic transmission of metering information. Control direction The master can send: b General commands (enable/disable functions: protection, recloser, etc.) b A general interrogation request to obtain the current value of slave equipment status conditions and indications b A transmission request for disturbance records and other records b Time synchronization commands b Commands to reset the interface Communication initialization The slave interface only becomes operational once an initialization request sent by the master device has been received. The absence of polling by the master is detected by the slave and this stops. To re-establish, the master device must send a reset request. Information characteristics All information exchanged between the control system and the protection equipment features: b A function number b An information number b The ASDU number used to transmit the information b The cause of the transmission 4 SEPED305002EN - 0/203

7 IEC IEC protocol 0 Access to Sepam data Sepam is a multifunctional digital relay, which supplies a great deal of information. Sepam data is categorized on the basis of function. Compliant with the data model defined in IEC , all data is identified by a function number (FUN) and an information number (INF). A detailed description of the Sepam data table, including function number and information number, appears in the Sepam data table section. List of IEC standard functions Sepam supports the subset of standard functions shown below. Sepam uses the standard FUN and INF numbers for these functions. FUN Function name 255 System 60 Overcurrent protection List of Sepam-specific functions Sepam uses private FUN and INF numbers for these functions.

12 IEC IEC protocol 0 Sepam data table All Sepam data that can be exchanged with a supervisor via the IEC protocol is listed in two tables: b The monitoring direction data table, which lists all Sepam data to be transmitted to the supervisor. b The control direction data table, which lists all supervisor data to be transmitted to Sepam. Description of the Sepam data table The following information is provided for each data item: b The ASDU (Application Service Data Unit) number b The value of the FUN (Function) and INF (Information) identifiers b The value of the COT (Cause Of Transmission) field b A GI (General Interrogation) marker b The Sepam data semantic b The Sepam series for which the data is available For Sepam series 20, Sepam B2X (dedicated to voltage applications) are distinct from Sepam S20, T20 and M20 (dedicated to current applications). The effective availability of a Sepam data item also depends on the Sepam type and function parameter settings. ASDU: Application Service Data Unit The ASDU number identifies the standard data structure used by Sepam for data transmission. FUN and INF: Function number and information number Each Sepam data item is identified by: b The number of the function to which the data belongs: FUN b The information number of the basic data: INF COT: Cause Of Transmission The COT value shows the cause of transmission of the data. Monitoring direction In the monitoring direction, Sepam uses the following COT values: COT Label Spontaneous Information produced spontaneously following a change of state (date-tagged event) 2 Cyclic Information produced cyclically by Sepam (measurements) 3 Reset (FCB) Response to command to reset the frame count bit (FCB) 4 Reset (CU) Response to command to reset the unit (CU) 5 Start/restart Response to command to initialize the interface 8 Time synchronization Acknowledgment of time synchronization command 9 General interrogation Information produced in response to a general interrogation command 0 End of general interrogation Termination message of a general interrogation cycle 2 Remote operation Change of state resulting from a supervisor command 20 Positive acknowledgement Positive acknowledgment of command 2 Negative acknowledgement Negative acknowledgment of command Control direction In the control direction, Sepam supports the following COT values: COT Label 8 Time synchronization Time synchronization command 9 General interrogation Initialization of a general interrogation cycle 20 General command Command from the supervisor such as open/close breaker, enable/disable a function, etc. GI: General Interrogation The GI marker indicates whether the data is produced in response to a general interrogation request. For this data, each change of state ("OFF" to "ON" and "ON" to "OFF") is also transmitted spontaneously. 0 SEPED305002EN - 0/203

23 IEC Configuring the interfaces 0 Presentation The Sepam interfaces must be configured using SFT284 software. The IEC protocol is available with the ACE969TP-2 or ACE969FO-2 interfaces. Several parameter categories have to be configured once the interface has been selected: b The configuration parameters for the physical layer of the E-LAN port b The configuration parameters for the physical layer of the S-LAN port b The configuration parameters for functions specific to the IEC protocol (advanced S-LAN port parameters) PE8002 Access to configuration parameters These parameters can be accessed from the Communication configuration window in the SFT284 software. To access this window: b Display the Sepam configuration screen in SFT284. This screen will vary according to the type of Sepam used. b Select the Communication option. b Click : the Communication configuration window appears. b Select the type of interface used (ACE969TP-2 or ACE969FO-2). b Select the IEC03 protocol (S-LAN port). SFT284: Sepam series 80 hardware configuration. PE8003 Configuration of the E-LAN port Configuration of the physical layer The E-LAN port on the ACE969TP-2 and ACE969FO-2 interfaces is a 2-wire RS 485 port. The configuration parameters for the physical layer of the E-LAN port are: b Sepam address b Transmission speed b Parity check type Parameters Authorized values Default value Sepam address to 247 Speed 4800, 9600, 9200 or bps bps Parity No parity, Even or Odd Odd Configuration of the physical layer of the E-LAN port on an ACE969TP. Configuration tips b The Sepam address MUST be assigned before Sepam is connected to the E-LAN network. b You are also strongly advised to set the other physical layer configuration parameters before connecting to the network. b Modifying the configuration parameters during normal operation will not disturb Sepam but will reset the E-LAN port. If SFT284 is connected to Sepam via the E-LAN network, any between Sepam and SFT284 will be interrupted. SEPED305002EN - 0/203 2

25 IEC Configuring the interfaces 0 Configuration of the S-LAN port: IEC protocol Configuration of the IEC protocol functions The configuration of the IEC protocol functions is identical whether the ACE969TP-2 interface or the ACE969FO-2 interface is used. Click the Advanced parameters button in the ACE969-2 configuration windows to open the IEC 03 Protocol parameters window, in which the following can be configured: b The standard parameters as defined by standard IEC b The Sepam private data to be exchanged with the supervisor PE8005 Configuration of the standard parameters The standard IEC protocol parameters are as follows: b Cyclic ASDU period b Inactivity timer b Time synchronization period b Blocking of monitoring direction Configuration of the IEC protocol. Cyclic ASDU period Period during which cyclic data, such as measurement information, is generated and updated by Sepam. This parameter, which is expressed in seconds, must be set consistently with the interval at which this data is polled by the supervisor. Inactivity timer In normal operation, the supervisor sends polling requests to the Sepam units at regular intervals. Each Sepam monitors the activity of the supervisor by checking that polling requests are being received regularly. If a Sepam fails to receive requests during a configurable period (the inactivity time delay), it will lock its port and cease to respond to requests sent subsequently by the supervisor. To re-establish with a locked Sepam, the supervisor must initiate a reset. Time synchronization period Time synchronization is transmitted via ASDU 6. If this ASDU has not been received at the end of time T (time synchronization period), Sepam will assume that its clock setting may be inaccurate and will assign the information "Invalid time" to time-tagged data. Blocking of monitoring direction Sepam can suspend the transmission of data in the monitoring direction, in accordance with the procedure specified by IEC Parameters Authorized values Default value Cyclic ASDU period 0 to 60 seconds 0 seconds Inactivity timer 0 to seconds 0 (infinite) Time synchronization period 0 to minutes 0 Blocking of monitoring direction No or Yes No SEPED305002EN - 0/203 23

26 IEC Configuring the interfaces 0 Selection of the data to be exchanged Sepam private data is categorized in three subsets: b States and indications b Protections b Measurements In each subset, the data is organized into functional groups. A functional group is identified by a function number (FUN). The data groups to be exchanged with the supervisor can be selected in the configuration window. Only the data groups required for the application should be selected, in order to avoid overloading unnecessarily (in particular in the event of a general interrogation on the part of the supervisor).

33 IEC Appendix : Sepam data coding 0 Command coding: ASDU 20 Commands are sent to Sepam (enable/disable functions, open/close, remote controls, etc.) via ASDU 20. A command is always confirmed by Sepam through generation of an acknowledgement message by return using ASDU (COT 20). The General Command ASDU includes an identification number (Return Information Identifier, from 0 to 255), selected arbitrarily by the master. This number is copied as is by Sepam into the Command Acknowledgement ASDU so that a link can be established with the Command ASDU. The value of the command is coded in the DCI (Double Command Information) byte; the authorized values are OFF () and ON (2).

34 IEC Appendix 2: File transfer 0 General Presentation Sepam records information, in the form of files, produced by the following functions: b Disturbance records b For Sepam series 60 and Sepam series 80 only: v Tripping contexts v Out-of-sync context v Motor Start v Motor Trend v Data Log These files can be retrieved using a file transfer procedure based on private ASDUs 254 and 255. Types of file to be transferred Definitions The files that can be transferred from Sepam to the supervisor are: b DR (Disturbance Records) directory file, which contains the information required for transferring disturbance record files saved in Sepam b TR (Tripping Records) directory file, which contains the information required for transferring Tripping context files saved in Sepam b NS (Out-of-sync context) directory file, which contains the information required for transferring Out-of-sync context files saved in Sepam b MS (Motor Start) directory file, which contains the information required for transferring Motor Start files saved in Sepam b MT (Motor Trend) directory file, which contains the information required for transferring Motor Trend files saved in Sepam b DL (Data Log) directory file, which contains the information required for transferring Data Log files saved in Sepam b Disturbance record files, which contain data saved in Sepam on events via the Disturbance recording function b Tripping context files, which contain data saved by Sepam on tripping b The Out-of-sync context file, which contains data saved in Sepam when there is a lack of synchronization b Motor Start files, which contain data saved in Sepam on motor starting b Motor Trend files, which contain data saved in Sepam when this data is calculated (on motor starting) b Data Log files, which contain data saved in Sepam on tripping of this function 32 SEPED305002EN - 0/203

The DR directory file is read by the supervisor 2. The contents of the DR file is interpreted by the supervisor, to identify the Disturbance record file to be transferred 3. The selected Disturbance record file is read The other files (Tripping context, Out-of-sync context, Motor Start, Motor Trend, and Data Log) are transferred in the same way, using the directory files TR, NS, MS, MT and DL, respectively. SEPED305002EN - 0/203 33

36 IEC Appendix 2: File transfer 0 General Reading a file Procedure The same procedure applies for reading all files (directory files and data files). This consists of an exchange of requests/responses between the supervisor and Sepam: b The supervisor sends requests based on ASDU 254 (private ASDU). b Responses from Sepam are retrieved by the supervisor via requests to scan class data. Responses from Sepam are based on ASDU 255 (private ASDU). A file is read in three stages:. The file to be transferred is opened via an Open request/response 2. Data is transferred from the file through a succession of Read Block requests/ responses 3. The file is closed via a Close request/response Notes b Only one file can be open at any one time: the directory must therefore be closed after reading, in order to be able to read one of the files in this directory. b For an open file, only one transfer is permitted at any one time. b A data block contains a maximum of 238 bytes. The number of Read Block requests necessary to transfer a file depends on its size. ASDU requests and responses ASDU FUN Control direction Monitoring direction Description b Open request b Open response b Read Block request b Read Block positive response b Read Block negative response b Close request b Close response 34 SEPED305002EN - 0/203

37 IEC Appendix 2: File transfer 0 General Checking and processing errors Sepam performs a series of checks to ensure that a file is read correctly. Any error that occurs whilst a file is being read causes the file to be closed automatically by Sepam. Block number sequence check Data blocks are numbered starting at 0. Blocks must be read in ascending order. It is possible to reread the same block i several times, as long as no request has been made for the next block i+ to be read. A sequence error in the block number requested in a Read Block request generates a negative Read Block response (status = incorrect block number). Data integrity check A Disturbance record file, Tripping context, Out-of-sync context, Motor Start, Motor Trend or Data Log file in Sepam can be overwritten at any time by a new record if a new event occurs. If a file is in the process of being read, then data obtained by the supervisor will be corrupt. Sepam indicates this error scenario in the Read Block negative response (status = file corrupted). Once the file is corrupted, it closes automatically. In this case, the Close request serves no purpose. However the response to the Close request will be: status = incorrect file identifier. Inactivity check: aborting a read operation Sepam manages an inactivity time delay when a file read operation has been initialized, and throughout the entire course of the read operation. If there is more than 60 seconds between two Read Block requests or between the last Read Block request and the Close request, Sepam automatically closes the file. A spontaneous Close response is generated by Sepam (status = file closed on detection of inactivity). Execution reports Responses from Sepam contain an execution report coded in the Status field of ASDU 255. The values possible in the Status field are listed in the table below: Status Description 0 OK 3 Open error response: file does not exist 5 Open error response: file already open 6 Read Block negative response and Close error response: file identifier incorrect 6 Read Block negative response and Close error response: file not open 7 Spontaneous Close response: file closed on detection of inactivity 9 Read Block negative error response: file corrupted 20 Read Block negative response: block number incorrect SEPED305002EN - 0/203 35
