The intent of this section is to provide a quick understanding of how the 104
gateway 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 data
transmission systems for monitoring and controlling geographically widespread
processes. This protocol is similar to 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.
