Intouch 7.11 - How to register an event when a setpoint change?

Dear all, I have to register an event/alarm when operator change the setpoint value.
Do I have to create a script for this?
Do you have an example to help me?

I have to register the user changes too (operator to supervisor, etc.).

My intouch version is 7.11. Do you know how to do??

I appreciate!

If you have a historian setup, you could select the setpoint and operator to be logged then generate a query to report setpoint and operator when setpoint changes. Another method is to use filewritefields script to write setpoint, operator, and date/time to a text file.
