try to use some generic display name and then append it with one unique value, so that whenever you run the process multiple times, the process will be visible with unique name

Hello Saratt ,

1) thinking you are positive about "having the rule", is this the last version of the rule?
2) what you get in the logs?
3) are you sure is the process name rule? what if you hardcode the name? everything still works? what about setting initial values to pv's when you instantiate the process.

Best regards
Jose

Are you positive that Process_Display_Exp() is present in the environment you're using?

You might need to include more detail as to what's in your process display name rule - I have hundreds of process models whose process display names are expression rule based and they work fine.
