9.3
HMI description
The « COMMUNICATION » menu depends on the rear communication protocol
which is implemented into the MiCOM relay. This protocol must be selected at the
order among the following protocols : Kbus/Courier, Modbus, IEC60870-5-103.
Please refer to the cortec page (Chapter 3 of this Technical Guide).
9.3.1
Courier Interface
Courier is the communication language developed by A
REVA
T&D
to allow remote interrogation of its range of protection relays. Courier works
on a master/slave basis where the slave units contain information in the form of a
database, and respond with information from the database when it is requested by a
master unit.
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 98 and NT compatible software package which is specifically designed for
setting changes with the relay.
To gain access to the “COMMUNICATION” menu from the default display, press
2
once and
6
3 times. The HMI is described below :
COMMUNICATION
Heading of the “COMMUNICATIONS” menu

Note :
message only seen if the communication has been
enabled
9.3.2
Modbus interface
Modbus is a master/slave communication protocol which can be used for network
control. In a similar fashion to Courier, the system works by the master device
initiating all actions and the slave devices (the relays) responding to the master by
supplying the requested data or by taking the requested action. Modbus
communication is achieved via a twisted pair connection to the rear port and can be
used over a distance of 1000m and up to 32 slave devices.
