The events created in the terminal available for the IEC protocol are based on the event function
blocks EV01 - EV06 and disturbance function blocks DRP1 - DRP3. The commands are repre-
sented in a dedicated function block ICOM. This block has output signals according to the IEC
protocol for all commands.
2.5.3 IEC 60870-5-103
The tables below specifies the information types supported by the REx 5xx products with the
communication protocol IEC 60870-5-103 implemented.
To support the information, corresponding functions must be included in the protection terminal.
There are no representation for the following parts:
• Generating events for test mode
• Cause of transmission: Info no 11, Local operation
Glass or plastic fibre should be used for the optical ports. BFOC2.5 is the recommended inter-
face to use (BFOC2.5 is the same as ST connectors). ST connectors are used with the optical
power as specified in standard, please see the Installation and commissioning manual.
For the galvanic interface RS485, use terminated network according to EIA Standard RS-485.
The modem contact for the cable is Phoenix MSTB2.5/6-ST-5.08 1757051.
For more information please see the IEC standard IEC 60870-5-103.
