General
M11874-3 v5
IEC 60870-5-103 is an unbalanced (master-slave) protocol for coded-bit serial
communication exchanging information with a control system, and with a data
transfer rate up to 38400 bit/s. In IEC terminology, a primary station is a master
and a secondary station is a slave. The communication is based on a point-to-point
principle. The master must have software that can interpret IEC 60870-5-103
communication messages.
