Note: *May vary according to relay type/model
The relay is a slave unit which is designed to be used with a Courier master unit such
as MiCOM S1, MiCOM S10, PAS&T, ACCESS or a SCADA system. MiCOM S1 is a
Windows NT4.0/95 compatible software package which is specifically designed for
setting changes with the relay.
To use the rear port to communicate with a PC-based master station using Courier, a
KITZ K-Bus to RS232 protocol converter is required. This unit is available from
ALSTOM T&D Protection & Control. A typical connection arrangement is shown in
Figure 7. For more detailed information on other possible connection arrangements
refer to the manual for the Courier master station software and the manual for the
KITZ protocol converter. Each spur of the K-Bus twisted pair wiring can be up to
1000m in length and have up to 32 relays connected to it.
