How to have timestamp from IED for alarms(events) in a 800xA Alarm(event list) using MMS on CI868 ( IEC61850)
We are using CI868 module for IEC-61850 communication in a station with 6 ABB protection relays (type REG670).
How to have timestamp from IED for alarms and events in a 800xA Alarm and event list using MMS RCB for LN's OTHER than XCBR and CSWI? (Because in the manual there is only explanation on how to get SOE(timestamp) for XCBR and CSWI LN nodes and not for other LN's, for example PTRC LN)
800xA is communicating to IED's through IEC61850 MMS communication. 800xa is basically linked to the tool called CET-communication engineering tool and this tool will act as a OPC server. It will collect the data from relays and 800xa will collect the data from OPC using service structure. CET is having the SNTP client and it should be configured properly, means enter the SNTP server address in the configuration
Now time stamp will be received from CET tool and it will be send to 800xa. This is mainly for the input data send by the IED's.
XCBR and CSWI logical nodes are dealing with control commands and time stamp is allowed for this logical node in output direction
PTRC logical node is used for goose publisher and CI868 will not allow the time stamp in goose publisher and when mapping goose control block,we map only signal and quality.
