The COMMVALID output will become LOW when the sending IED is under total failure
condition and the GOOSE transmission from the sending IED does not happen.
The TEST output will go HIGH if the sending IED is in test mode.
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.
14.9 IEC 60870-5-103 communication protocol
14.9.1 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.
