Hi,
I'm using a Lab Entry (LE) block with the standard faceplate but have problems with parameters when I'm logged in as a operator. Our DeltaV 11.3 has Parameter Security Default lock: Restricted Control and need to add all parameters that operators should write to.
In Books Online for the LE block it says that the only parameters written to is "DELAY" and "OUT" but after some investigation I found 3 more parameters that I hade to include in the Parameter secyrity list ("SAMPLE_HR", "SAMPLE_MIN", "SAMPLE_PM"). After including them, the function (time and value store) is working but the operator still gets the error message.
As an admin, the function works correct without errors and also if I change the Parameter Security Default lock to Control. Perhaps someone have access to frsLabDataEntry and can see what else is happening in that script or have had the same problems before.

Petra,
Most likely your problem is because the parameter TRIGGER isn't in the Parameter Security table. Add this to the table with Control Lock and then put Default lock back to Restricted Control, do you download changed setup data and I think it will work.
The form also uses OUT_HI_LIM, OUT_LO_LIM, MIN_DELAY and MAX_DELAY but I believe that all of these are reads and should be causing your error.
Best of luck,
Matt
