Alarm Definition (non-GEM version)

Alarm notification definitions allow arbitrary definition and sending of the content of the alarm notification used by S5F1.
This is completed just by controlling the alarm occurrence/recovery trigger and the register that corresponds to the prescribed
alarm at the programmable controller CPU.
Operations during Alarm Notification
When the occurrence of (or recovery from) an alarm has been detected, the fact that a prescribed alarm occurred (or was
recovered from) is reported (S5F1 alarm sending) regarding a location in which the register status changed.
