IEC61850 OPC SERVER TO ABB REF615 RELAYS
Hi All,
I am communicating REF620 relays to 800xA 6 using IEC61850 CET opc server. But in 800xA the analog values like current, voltage are not updating at all untill a particular graphics page is refreshed.
But the digital values like local/remote of relay update correctly without problem
Is this normal behaviour of IEC61850 or something went wrong in the communication.

When you open the Graphics Page, the Values are requested from the IED directly, while for value updates without changing Graphics, you need the Report Control Blocks (RCB) on the IED configured to send those updated Values to CET. In your case either Report Control Blocks are not configured correctly or the configuration differs between CET and the IEDs.

Please check for current and voltage LN's are added in RCB's in the IED
Hi,
Kindly check the required analog signla's LNs are there in the Dataset. And the same dataset shall be mapped to RCB and the respective RCB shall be mapped to CET as Client.
Also kindly check the configurations like RCB's Trigger Options and deadband settings in the Relay.

Hi
as you see in capture(attachment) the current and voltage LNs are defined in Dataset (DSB) and connected to Client1.
i configure IEC 61850 in PCM600 and Download it to Relay after that i Export SCD file from PCM600 and Import it to CET but the current and voltage does not update automatically.
another question is for IEC61850 configuration, PCM600 is enough or we need another program like IET600?
