5.2 IEC-60870-5-101 Slave Protocol Implementation
This section presents an overview of how the 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 configuring and modifying the
implementation of the protocol with the 101S, refer to Configure the Module.

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 one 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 gateway works as an 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.
