• Alarm
The available alarm types are high limit alarm, low limit alarm, delay high limit alarm,
and delay low limit alarm.
The range of alarm values is as follows:
Type Alarm Values
H, L, T, t –9999999 to 99999999 ignoring the decimal point
For alarm conguration instructions, see section 3.7.
* If you change the On/Off or expression setting of a computation channel, the alarm on that
channel will be set to Off.
• Alarmdelay>Time
Set the alarm delay using an integer in the range of 1 s to 3600 s.
• Tag>Characters
