Alarm log

The Model 3711 alarm log contains the change in the state of any alarm signal that has been enabled.
The alarm log can store up to 240 alarms in a "circular" log. When the log is full, each new alarm
overwrites the oldest alarm.
Each alarm log record includes:
• Time and date stamp
• Alarm clear or set indicator
• Tag name of the associated point, or a 14-byte detail string in ASCII format
An FST can create an entry in the alarm log, but cannot read and parse an alarm log entry.
The alarm log can be accessed by host programs. To access the alarm log and acknowledge alarms
from a Modbus program, see Section 12.6.3.
Note: The alarm log is not saved in flash memory or saved with a device configuration file. The alarm
log must be saved or backed up separately (see Section 8.4.3).
