9.2 IEC-60870-5-104 Protocol Implementation
The intent of this section is to provide a quick understanding of how the PTQ-
104C 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 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 PTQ-104C operates as an IEC-60870-5-104 client; sending read or write
commands to remote server(s).
