I’d like to ask the experts here: what do 03MHS, 03MOV, 03MZLC, and 03MZLO mean in the PID diagram below? What does 10511 mean again?

It should be an electric valve; 10511 is the tag number for this valve. 03MHS (high stop) and 03MOV (valve) belong to the control system ； 03MZLC (off state) and 03MZLO (on state) belong to the SIS system. The numbers in parentheses are just my estimates and may not be accurate.

The first page of the PID diagram should be the design legend, which should include examples of instrument naming

Signal for the on/off status of the electric door!
