I ran into a similar issue when I was tasked with generating an event entry for all discrete device state changes driven be automated phase logic. What I found is you can't write the string value (*.CVS) unless the name set option you are reading is set to "User Selectable". In my case I was trying to read the EDC/PV and write it's string value to the event log. I found setting the EDC/PV name set to user selectable was a bad idea and resulted in unreliable state change behavior in simulation. I ultimately had to create an identical name set for each unique EDC/PV name set, set the identical name set to "user selectable", assign it a parameter within each control module, and then I could write the EDC/PV to the parameter value, and read back the parameter string value. The other option is hard code IF-THEN-ELSE statements to sort through the name set integer value and write the desired string value back rather than trying to read it from the name set.

In this case, the named set values are all already user selectable.

That worked. Thanks!
