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.

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.

In CET there is some Diagnostics Data on the IEDs, where you can see if CET actually could connect to the RCB and you get Data Updates

in my RCB there is some digital signal like LocKeyHMI and some Analog signal like Voltage. digital signals are ok an updated automatically but analog signals have problem
i mean RCB is ok because digital signals updated automatically

no, usually (and with good reasons) Analog and Digital Signals are configured on different Report Control Blocks. As Parthiban answered check the configuration (datasets, trigger options) of the RCB

i just combine analog and digital in same RCB for testing RCB connection
i test all trigger options (Data change, Data update, Period, Quality Change)
you can see my dataset configuration in capture (attachment) it seems be ok

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?
