How the persistent rapid variable changes is tracked in abb opc ua server ?

I have created a persistent variable and is changing periodically in controller. I cannot see that in the dataFeed OPC UA client. The client is connected to server and irc5 is also connected to server. Can someone please point me to the proper documentation on how to subscribe for changes in rapid variable. 


  • Never mind. I uninstalled and reinstalled OPC UA server and it showed all my persistent variables
