Describe what the purpose of a “named set” is. Provide an example of a “command” and respective “status” type.

A named set is useful for quickly and accurately identifying the status of a device— whether it’s OPEN/CLOSED, ON/OFF, TRUE/FALSE. Example: - Command: //BPCS_XHS_103/DC1/PV_D.CV - Status: VLVNC-PV:CLOSED

(fire, gas, esd, lowlow level, valve closed)

Describe 2 reasons why it is easier to use the structured text expression editor, rather than typing in variables and function operators by hand.

1. The expression editor reduces spelling and syntax errors by offering auto-complete for tags and functions. 2. It speeds up programming because you select from lists rather than manually typing every element.
