The COMMVALID output will become LOW when the sending IED is under total failurecondition 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 crossto receive the binary single point values.The implementation for IEC61850 quality data handling is restricted to asimple level. If quality data validity is GOOD then the DATAVALIDoutput will be HIGH. If quality data validity is INVALID,QUESTIONABLE, OVERFLOW, FAILURE or OLD DATA then theDATAVALID output will be LOW.16.9 IEC 60870-5-103 communication protocol16.9.1 FunctionalityIEC 60870-5-103 is an unbalanced (master-slave) protocol for coded-bit serialcommunication exchanging information with a control system, and with a data transferrate up to 19200 bit/s. In IEC terminology, a primary station is a master and a secondarystation is a slave. The communication is based on a point-to-point principle. The mastermust have software that can interpret IEC 60870-5-103 communication messages.Function blocks available for the IEC 60870–5–103 protocol are described in sectionsControl and Monitoring.The Communication protocol manual for IEC 60870-5-103includes 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 RS485serial communication interface on the COM03 or the COM05 communication module.The functions Operation selection for optical serial OPTICALPROT and Operationselection for RS485 RS485PROT are used to select the communication interface.See the Engineering manual for IEC103 60870-5-103 engineeringprocedures in PCM600.The function IEC60870-5-103 Optical serial communication, OPTICAL103, is used toconfigure the communication parameters for the optical serial communication interface.Section 16 1MRK 502 048-UUS AStation communication654Technical manual
