This is typically used for sending apparatus
position indications for interlocking or
reservation signals for 1-of-n control. GOOSE
can also be used to exchange any boolean,
integer, double point and analog measured

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 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.
