Technical manual
The input of this GOOSE block must be linked in SMT by means of
a cross to receive the binary single point values.
The implementation for IEC61850 quality data handling is restricted
to a simple level. If quality data validity is GOOD then the
DATAVALID output will be HIGH. If quality data validity is
INVALID, QUESTIONABLE, OVERFLOW, FAILURE or OLD
DATA then the DATAVALID output will be LOW.

IEC 60870-5-103 communication protocol

Functionality
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.
Function blocks available for the IEC 60870–5–103 protocol are described in sections
Control and Monitoring.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.
