Alarm History parameters
Field Description
Monitoring Set the start device (see notes below) and the number of alarms to be recorded.
Select which alarm status should trigger the recording of the alarms.
Record Number of Records: Set the number of records to be stored. The value you enter
must be greater than the setting in "Number of Lines" on the "Color and Form" tab
(see p. 203). The maximum number of records is displayed below for your information.
The alarm history and the line graph use the same memory area so the recordable
maximum may vary considerably (see notes below).
Record Information : Select the information you wish to record.

Triggered: Time when the start device turns ON or OFF.

Acknowledged: Time when an alarm has been acknowledged, e.g. when the user
pressed a function switch (the alarm list part needs to be combined with a function
switch in this case).

Recovered: Time when the alarm has been reset.
When Memory is Full : Select what should be done when the memory is full.

For general purpose serial communication, the start device needs to be an
internal GT register, e.g. WGR10 (default setting).

The total memory for the alarm history and the sampling data for line graph
parts (see p. 208) is 28160 bytes. Each alarm record uses 16 bytes for initial
information and 10 bytes for each event.
