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 feeder 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.
Profibus-DPV1 communication by using SPA-ZC 302 on the rear
connector X3.2
The 9-pin D-type subminiature male connector (RS-232 connection) on the rear
panel connects the feeder terminal to the distribution automation system via the
Profibus protocol. The interface between the feeder terminal and Profibus can be
made through the SPA-ZC 302 Gateway.
In the Profibus mode, the baud rate for relay port X3.2 is set to 38400. The SPA-CZ
302 Gateway should be set to the same baud rate. If the SPA-ZC 302 Gateway is
connected to multiple terminals, the "Protocol 2" parameter should be set to SPA
mode and the SPA baud rate for port X3.2 to 19200.
LON/SPA bus communication on the rear connector X3.3
The 9-pin D-type subminiature connector (RS-485 connection) on the rear panel
connects the feeder terminal to the distribution automation system via the SPA bus
or the LON bus. The fibre-optic interface module type RER 103 is used to connect
the feeder terminal to the fibre-optic communication bus. The module RER 103
supports both SPA bus and LON bus communication.
The other communication parameters for the rear interface RS-485 are set also via
the Communication menu.
Front panel optical RS-232 connection for a PC
The optical connector on the front panel isolates the PC galvanically from the feeder
terminal. The front connector for the PC is standardized for ABB relay products and
requires a specific opto cable (ABB art. No 1MKC950001-2). The cable is
connected to the serial RS-232 port of the PC. The other communication parameters
for the rear RS-485 interface are also set in the Communication menu of the
REF 54_ feeder terminal.
The front panel is intended for the connection of a PC for configuring the feeder
terminal with the CAP 50_ tools. The front interface uses the SPA bus protocol.
