Understanding IED Details

The IED details tool is used to view and edit the detailed options required to setup an IED within the system. This information is displayed in four main sections:

• Common Options

• Default Analog Scaling Options

• Protocol Specific Options

• Connections List

IED Common Options

The IED common options consists of the following fields:

• Control: The configured state of the IED. This is updated by actions menu options.

• Status: The actual state of the IED as reported by the system (not editable).

• Name: A unique IED name in the system, used for logging audit messages and errors.

• Protocol: Wwhat protocol is used to communicate with the IED.

• Commission: The commissioned state of the IED.

• FEP: Which FEP will communicating to the IED.

IED Default Scaling Options

The default scaling options are a definition of the analog scaling values that will be used for all analogs on an IED unless overridden by values on the input itself:

• Absolute Change: Default required absolute difference before being reporting

• Percent Change: Default required percentage difference before being reporting

• Offset Before Multiply: Default add value before multiply operation - use negative value for subtraction

• Offset After Multiply: Default add value after multiply operation - use negative value for subtraction

• Scale Multiplier: Default multiplier for analog values

IED Protocol Specific Options

The protocol specific section of the IED details screen varies depending of which protocol is to be used to communicate to the IED.

• DNP3 Options

• IEC60870-5-104 Options

• ICCP Options

DNP Options

IEC60870-5-104 Options

• Connect timeout (T0): Connection establishment timeout. Range 1 s to 255 s, accuracy 1 s. default 30 seconds.

• Acknowledge timeout (T2): APDU acknowledge timeout. Range 1 s to 255 s, accuracy 1 s. default 10 seconds, must be less than t1 ADPU timeout.

• Idle timeout (T3): Idle Timeout. Range 1 s to 48 h, resolution 1s, default 20 seconds.

• Max APDU Transmit (K): Maximum outstanding I format transmitted APDU, default 12. Range of values 1 to 32767 APDUs, accuracy 1 APDU.

• Max APDU Receive (W): Maximum outstanding I format received APDU, default 8. Range 1 to 32767 APDUs, accuracy 1 APDU - Recommendation: W should not exceed two-thirds of K.

• Station Address: Local IEC104 station number.

• Server Mode: Run as server instead of client. Y=Server N=Client (Default).

ICCP Options

• TSEL: Transport selector.

• Local Domain: Local domain name.

• Remote Domain: Remote domain name.

• Local Table ID: Local Bilateral Table ID.

• Remote Table ID: Remote Bilateral Table ID.

• TCP/IP Address: Optional IP address for the Local VCC - Gates incoming connections, default is to accept connections on any IP address.

• Block 1: Periodic System Data: Status points, analogue points, quality flags, time stamp, change of value counter, protection events.

• Block 2: Extended Data Set Condition Monitoring: Provides report by exception capability for the data types that block 1 is able to transfer periodically.

• Block 3: Block Data Transfer: Provides a means transferring Block 1 and Block 2 data types as block transfers instead of point by point.

• Block 4: Information Messages: Simple text and binary files.

• Block 5: Device Control: \nDevice control requests: on/off, trip/close, raise/lower etc. \nand digital setpoints.

• Block 6: Program Control: Allows an ICCP client to remote control programs executing on an ICCP server.

• Block 7: Event Reporting: Extended reporting to a client of error conditions and device state changes at a server.

• Block 8: Additional User Objects: Scheduling, accounting, outage and plant information.

• Connection Mode: Connection direction - Inbound, Outbound, or Dual.

• Role: ICCP role (Client, Server, or Both).

• Reduce List: ICCP behavior option - negotiate non-existent points in transferset definitions.

• Mismatch Flag: ICCP behavior option - create csv file listing non-existent points in transferset definitions.

• Keep Alive: Periodically send MMS Identify request as keep-alive. Default=0 meaning do not send.

• Secure Mode: Enable/Disable secure ICCP.

• TLS Certificate: TLS public client certificate, or local private server certificate identifier - Secure Only.

• ACSE Certificate: ACSE public certificate, or local private certificate identifier - Secure Only.

IED Connections List

This section allows the configuration of one or more connections between the FEP and the IED itself. This is normally redundant connections to the same IED instance. Connections can be added or removed as required, and also enabled or disabled from a right-click context menu.

Each connection has the following options:

• Control: The configured state of the connection. This is edited by actions menu options.

• Status: the actual state of the connection as reported by the system (not editable).

• Name: A unique (on the IED) name for the connection, used for logging audit messages and errors.

• Description: optional description.

• Order: A defined order to try the connections – lowest value first.

• IP Address: The TCP/IP address of the FEP for the connection.

• Port: The TCP/IP port for the connection.

• Poll Period: The period to collect poll statistics in seconds.

• Stats Period: The frequency to report the statistics.

• Recovery Percent: Required percentage of good vs bad polls for connection recovery.

• Failure Percent: Required percentage of good vs bad polls for connection failure.

ICCP Remote VCC List – only for ICCP IEDs

This ICCP Remote VCC definition has all of the same columns as the IED connections defined above and the following additional columns

• TSEL: Transport selector.

• SSEL: Session selector.

• PSEL: Presentation selector.

• AP TITLE: Application Process Title.

• AE QUALIFIER: Application Entry Qualifier.

• Application Entry Qualifier: TLS public client certificate, or local private server certificate identifier - Secure Only.

• ACSE CERTIFICATE: ACSE public certificate, or local private certificate identifier - Secure Only.
