5.7 EVENT MONITORING

BITWISE EVENT DATA

Some of the most common events are supported as individual bits (0b1 means the event is Active, 0b0

means the event is Inactive). See Appendix A for full definition of these registers.

 Alarm Group 3 Horn (352)

 Alarm Group 4.1 (354)

 Alarm Group 4.2 (355)

 Alarm Group 4 Horn (356)

LEGACY EVENT LOG DATA

For legacy use only. For new applications, see “Module Event Log Data” section.

 Log Entry Index (1033)

 Log Entry (1034) – format is the same as the Module Event Log Entry (1500+) registers
