6.49 S5F1 - Alarm Report
S5F1 [W] * H<-E

Severity
<U4 ALID> * ALID - Alarm ID

This message is the "normal" message that the Equipment uses to report alarms. In order for this message to be used, the
Equipment Constant "ConfigAlarms" must be set to "0".
If the Equipment Constant "ConfigAlarms" is set to "0", the Equipment sends S5F1 instead of the normal S5F73 Alarm
Notification Send.
The equipment reports that an alarm condition has changed.
ALID identifies the Alarm.
The high-order bit of ALCD will be "1" if this alarm is currently On (Unsafe), or "0" if it is currently Off (Safe). The low-
order seven bits of ALCD contain the severity code for this alarm.
ALTX contains up to 40 bytes of Alarm Text. See "Appendix C" for a table of possible Alarms which can occur.
Equipment Constant "WBitS5" controls whether the Equipment sends S5F1 with W-Bit "1" (Reply Expected) or "0" (No
Reply Expected).
6.50 S5F2 - Alarm Acknowledge
S5F2 * H->E
<B [1] 00>. * ACK5 - Alarm Acknowledge
The Host acknowledges the Alarm Report. This Equipment ignores the ACKC5.
