5.2 IEC-60870-5-104 (104S) Protocol Implementation
The intent of this section is to provide a quick understanding of how the 104S
module implements the IEC-60870-5-104 protocol, without going into complex
details of the specification.
The IEC-60870-5-104 protocol applies to Telecontrol equipment and systems
with data transmission for monitoring and controlling geographically widespread
processes. This protocol consists essentially of the IEC-60870-5-101 protocol,
with the addition of TCP/IP as the transport mechanism.
Any application with the IEC-60870-5-104 protocol consists of a client
(Controlling Station) and one or more servers (Controlled Stations). The client
constantly monitors and controls the data from each server in the TCP/IP
network.
The MVI56-104S works as an IEC-60870-5-104 server; it can send monitor data,
receive commands, or generate events to the client unit.
