Protocol Implementation
This section presents an overview of how the MVI56-101S works, while skipping
the complex details of the protocol specification. If you require more information
about the implementation of the protocol, refer to the protocol specification (IEC
60870-5-101 2003). For more information on the configuring and modifying the
backplane implementation of the protocol with the MVI56-101S, refer to
Configuring the Module (page 31).
The IEC-60870-5-101 protocol applies to telecontrol equipment and systems with
coded bit serial data transmission for monitoring and controlling geographically
widespread processes.
Any application using the IEC-60870-5-101 protocol will have a master
(controlling station) and one or more slaves (controlled stations). The master will
constantly monitor and control the data from each slave in the network.
The MVI56-101S module works as a IEC-60870-5-101 slave. It can send monitor
data, receive commands or generate events to the master unit, as explained in
the following topics.
