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 tripping contexts 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 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 b Display of metering and diagnosis information b Display of logic states b Display of alarms Sepam series 60/80 ACE969-2 Two independent networks: S-LAN: IEC supervision E-LAN: For SFT284 operating functions. 2

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: 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 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

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

22 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 Parity 4800, 9600, 9200 or bps No parity, Even or Odd bps 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. 20

ACE969TP: 2-wire RS 485 S-LAN port The configuration parameters for the physical layer of the S-LAN port on the ACE969TP are: b Sepam address b Transmission speed b Parity check type Parameters Authorized values Default value Sepam address 0 to 254 Speed 4800, 9600, 9200 or 9200 bps bps Parity No parity, Even or Odd Even Configuration of the physical layer of the S-LAN port on an ACE969TP. PE8004 ACE969FO: Fiber-optic S-LAN port The configuration parameters for the physical layer of the S-LAN port on the ACE969FO-2 are: b Sepam address b Transmission speed b Parity check type b Link idle state: Light On or Light Off b Echo mode: Yes or No Echo mode must be activated when the Sepam is connected to an optical ring network. Parameters Authorized values Default value Sepam address 0 to 254 Speed 4800, 9600, 9200 or 9200 bps bps Parity No parity, Even or Odd Even Link idle state Light Off or Light Off Light On Echo mode Yes (optical ring) or No (optical star) No Configuration of the physical layer of the S-LAN port on an ACE969FO. Configuration tips b The Sepam address MUST be assigned before Sepam is connected to the S-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 S-LAN port. 2

24 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 22

25 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).
