5.5.4 Host Requests Alarm Status
The Host can use S5F5 to request the 7AF to report all alarms which exist and the ON/OFF state for each.
The Host can use S5F7 which is similar, but which causes the Equipment to report only those alarms (ALIDs) which are
Enabled, regardless of whether the alarm is ON or OFF.
5.5.5 Compatibility
The 7AF supports the following Alarm Report message formats for older host implementations (see "3.7.2 Gem
Configuration").
S5F71/S5F72
S5F73/S5F74

5.5.7 Related Collection Events
Each alarm defined on the 7AF has two unique collection events associated with it, a "Going-On" event, and a "Going-
Off" event. The CEIDs are listed in "Appendix B -- Collection Events".
5.6 Process Program Management
Processing on the 7AF is controlled by Process Programs. The Equipment requires selection of a Process Program for
each process. The 7AF supports the use of unformatted process programs.
5.6.1 Equipment Management of Process Programs
The 7AF provides a Process Program Library, implemented as a set of binary files maintained on a hard disk. Each
Process Program is identified by a unique Process Program ID (PPID). Each PPID is structured as a DOS file name,
consisting of up to 12 significant ASCII characters. The first 8 or less characters make up the file name. The next 3 or 4
characters are the DOS extension which begins with a “.” character. The Upper and lower case alphabetic characters are not
considered distinct, and the 7AF will not distinguish between them. The File names and extensions are categorized as
follows:
