DNP3 protocol
DNP3 (Distributed Network Protocol) is a set of communications protocols used to
communicate data between components in process automation systems. For a detailed
description of the DNP3 protocol, see the DNP3 Communication protocol manual.

IEC 60870-5-103 communication protocol
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 19200 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.
The Communication protocol manual for IEC 60870-5-103 includes the 650 series vendor
specific IEC 60870-5-103 implementation.
IEC 60870-5-103 protocol can be configured to use either the optical serial or RS485
serial communication interface on the COM03 or 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.
See the Engineering manual for IEC103 60870-5-103 engineering
procedures in PCM600.
The function IEC60870-5-103 Optical serial communication, OPTICAL103, is used to
configure the communication parameters for the optical serial communication interface.
The function IEC60870-5-103 serial communication for RS485, RS485103, is used to
configure the communication parameters for the RS485 serial communication interface.
