When using individual Select or Operate Tags, the value of these Tags corresponds to the CtlVal (Operation) code.
Whenever a new command is received, the Block or Tag triggers an OnRead event. Blocks or Tags with a configured EnableDriverEvent property also trigger an OnTagRead event. On this event, the application must send the requested operation to another system or Driver and then report the result. To report a result, the Block or Tag must be written back. If the CtlVal value is the same, the operation is considered successful, otherwise it is considered a failure.
