Hello i am using opc FBs to connect to some opc server, read, write & monitor items.
While i am not having issues creating & adding new items to the monitored items list, unfortunately i am not able to delete items from the list.
In the demo example shown on codesys store, we don't have any facility to delete monitored items from the list. (Not at least through visu)
But their are methods (DeleteMonitoredItem) provided on UaMonitoredItem FB to do this.
I tried calling this method but without any success. (So after calling this method, if the item is successfully deleted from the list then i should get a state change callback & the status of the item should be deleted.)
But unfortunately this doesn't happen. And i continue get value changes callbacks from the server on this particular item.
Could somebody help me here???
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
