Alarms

Historical information is stored in the alarm table. This table contains archived information
for up to 32 alarm records for each PLC. The records store information for both system
alarms and optional user-defined alarms. Each alarm record consists of an identifier for the
event that initiated the entry, along with a date/time stamp to indicate when the event
occurred. Typical events include change of Hot Standby mastership, loss of PLC power,
program restart, and loss of I/O devices.
