​.AlarmROCEnabled dotfield

Enables or disables rate-of-change events and alarms.

Category

Alarms

Usage

TagName.AlarmROCEnabled

Parameter

TagName

Any integer, real, indirect analog tag, or alarm group.

Remarks

When .AlarmROCEnabled is set to 0, all rate-of-change condition events and alarms are ignored. They are not stored in alarm memory, nor are they written to disk. It is very important to re-enable events/alarms, whenever possible, to avoid data loss.

This is the opposite of the .AlarmROCDisabled dotfield.

Data Type

Discrete (read/write)

Valid Values

0 = Disable alarms

1 = Enable alarms (default)

Example

The following example disables the rate-of-change alarms of the Tag1 tag:

Tag1.AlarmROCEnabled=0;
