Initialize Alarm/Event History ($SB32)
$SB32 initializes alarm and event history data. When $SB32 is turned ON, the alarm and event history
information recorded in the PT is initialized. Once the initialization has been completed, the system
automatically turns OFF $SB32.
The history data to be initialized can be specified using $SW40.
Save Alarm/Event History ($SB33)
$SB33 saves alarm and event history data. When $SB33 is turned ON, the alarm and event history
data is saved to the Memory Card as a CSV file. Once the data has been saved, the system auto-
matically turns OFF $SB33.
Alarm data is output to log\Alarm.csv (classified into high, middle, and low level alarms) and event data
is output to \log\Event.csv files on the Memory Card. The file names are fixed, and files previously out-
put to the Memory Card will be overwritten.
If no alarms have accumulated, alarm data will not be saved. ($SB33 will turn OFF and $SB47 will not
turn ON.)
