def ioc():
"""
Start MorIOC servers for ALL PVs used by:
- OperationMessageStatus (STATUS, STATUS-DATE)
- OperationMessageEntry (OP-DATEi, OP-MSGi)
- OperationMessage (OP-MSG-tmp)
- MachineStatus (CATEGORY, DOWNTIME)
One MorIOC per prefix:
- For each ID in IDS: 'SF-OP:{ID}-MSG'
- For each beamline in BEAMLINES:'SF-STATUS-{beamline}'
Important decisions:
- Enums are declared with pcaspy-style dicts so enum_strs are present.
- OP-MSG-tmp is hosted EXACTLY as the production code expects (lowercase),
and aliased to OP-MSG-TMP to be robust.
- We seed values ONCE; inside the loop we only call mor.serve() to
process CA traffic, without clobbering test writes.
