Transformer Terminal
Technical Reference Manual, General
RET 54_
69
The following table shows supported parallel communication protocols on the front
and the rear connectors of the RET 54_ transformer terminals.
5.1.13.2.
SPA/IEC_103 communication on the rear connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear
panel connects the transformer terminal to the distribution automation system via the
SPA bus or the IEC_103. The fibre-optic interface module type RER 123 is used for
connecting the transformer terminal to the fibre-optic communication bus for SPA
and IEC_103 protocol.
5.1.13.3.
DNP 3.0/Modbus communication on the rear connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear
panel connects the transformer terminal to the distribution automation system via the
DNP 3.0 or the Modbus protocol. The RS-485 interface module type RER 133 is
used for connecting the transformer terminal to the RS-485 communication bus of
these protocols.
5.1.13.4.
IEC 61850 communication by using SPA-ZC 400 on the rear
connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear
panel connects the transformer terminal to the distribution automation system via the
IEC 61850 protocol. In the IEC 61850 mode, the SPA-ZC 400 Bus Connection
Module is needed.
In the IEC 61850 mode, the baud rate for relay port X3.2 is set to 38400.
Furthermore, the mode includes a limited IEC 61850 GOOSE message support
when available in SPA-ZC 400.
