I'd like to know what are the available methods to implement a listener in PI. In our case, we would need something that can trigger an event when a change occur in a tag. Let's say for example I have a CIP on/off bit tag and when I have an "on" value, my listener would called a stored procedure to create a CIP event in another system. Also, what are the recovery possibilities for your listener method? (in case I have a problem in PI an need to recover a week worth of listener treatment for example)
Thank you for your help!
