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.
IEC 60870-5-103 protocol can be configured to use
either the optical serial or RS485 serial
communication interface on the COM05
communication module. The functions Operation
selection for optical serial (OPTICALPROT) and
Operation selection for RS485 (RS485PROT) are
used to select the communication interface.
The functions IEC60870-5-103 Optical serial
communication (OPTICAL103) and IEC60870-5-103
serial communication for RS485 (RS485103) are
used to configure the communication parameters
for either the optical serial or RS485 serial
communication interfaces.
