Vacuum Channel PVs
If a vacuum pump is off (as indicated by TRS8:SYS:VPS0xy:USE), then the severities of the corresponding value and status PVs for that pump should always show as NO_ALARM on the vacuum displays. If the pump is working, then the actual value and status severities should be shown. A set of soft channels were created for this purpose.
The channels containing actual PV data are:
The corresponding soft channels used to display severities depending on USE are:
See database file pack_vac.db for details.
