UNQUALIFIED_ENUM_CONSTANT

Severity: info

A bare identifier reference matches a member of exactly one enum type. Qualified form (E_State.IDLE) is clearer than the bare form (IDLE).

Why it matters. Bare enum refs work because IEC ST hoists enum members into scope, but they hide the type from anyone reading the code and break grep / IDE refactoring.

Settings. No check-specific config.

Trigger.

TYPE E_State : (IDLE, RUNNING); END_TYPE

eState := IDLE;                    (* fires, should be E_State.IDLE *)

🟦 info  UNQUALIFIED_ENUM_CONSTANT
'IDLE' looks like an enum member; consider writing it qualified
as E_State.IDLE

Fix. Qualify with the enum type name.
