5.1.13. Communication ports
The relay is provided with an optical communication port (infrared) on the front
panel. Rear communication is optional and requires a communication module,
which can be provided with either a plastic fibre-optic, combined fibre-optic (plastic
and glass) or RS-485 connection. The relay is connected to an automation system
via the rear connection. The optional rear communication module allows the use of
either the SPA bus, IEC 60870-5-103 or Modbus communication protocol.
For connection to the DNP 3.0 communication system, the relay can be provided
with an optional DNP 3.0 rear communication module with RS-485 connection. For
further information on optional rear communication module connections, refer to
Section 5.2.3. Serial communication connections.
