POU_NOT_COMMENTED

Severity: info. PLCopen: C2 — all code elements shall be commented.

A POU declaration has no comment immediately above (or on the same line as) it. PLCopen wants every code element to carry a header explaining its purpose, inputs/outputs, and any preconditions.

Settings. No check-specific config. A comment on any of the 6 lines immediately above the POU declaration (or on the declaration line itself) satisfies the rule. Interface declarations are exempt — the methods inside them are what carry the documentation.

Trigger.

FUNCTION_BLOCK FB_Bare                 (* fires *)
VAR ... END_VAR
END_FUNCTION_BLOCK

Not a trigger.

Fix. Add a one- or two-line header comment above the POU keyword.
