[Ganesh]

I am not able to write to MMS server using sendWrite() function. Can you please help me on how to provide DataValue to write to MMS server.

Hello, what type are you writing? To what variable name?

[Ganesh]

check it. Please let me know how to assign data value when writing into it.

Thanks and Regards

This is working for me via the standard "Write Data" dialog. Assure that the string you are writing to is a full name of an existent Data Set in MMS notation, see example with libiec61850 server example 3 (log from Capture view):

Anyway, for RCB configuration, use rather the specific "Configure and activate RCB" dialog - open it via right-click on the RCB name in IED View in reports tree section, click Configure RCB.
