Installation and Commissioning Manual
In the Loop topology, the interface receives the message from the fibre-optic
interface and passes it both to the fibre-optic transmitter and to the RS-485 interface.
In the Star topology, the interface receives the message from the fibre-optic receiver
and passes it only to the RS-485 interface. If the message is received from the
RS-485 interface, it is passed to the fibre-optic transmitter in both bus topologies.
The SPA bus communication uses Loop and light off modes, when the module
jumpers are in the Loop and light off positions. The LON
Star and light off modes, when the module jumpers are in the Star and light off
positions. The IEC 60870-5-103 bus communication uses Star and light on/off
modes, when the module jumpers are in the Star and light on/off positions.
®
In the LON bus communication the optional interface supports collision detection.
The Service Pin is connected via the RS-485 interface to the device's Neuron
which is connected to the interface.

SPA-ZC 400 Features

• IEC 61850 connectivity for RE_54_
• Internal power supply
• Easy-to-use configuration tool for the IEC 61850 data mapping
• Simultaneous dual port communication (SPA-ZC 400-MM and SPA-ZC 400-BB
®
versions) for LON and SPA
• Support of SPA communication over TCP/IP
All relay data can be routed through SPA-ZC 400. It is intended to route the process
data (status, measurements and commands) through the IEC 61850-8-1 bus and the
rest of the available data can be routed through SPA over TCP/IP.
It is not possible to use IEC 60870-5-103 and IEC 61850
simultaneously.
