Using Numeric Triggers
For numeric (analog) triggers, you can specify two thresholds for each
trigger to provide hysteresis (dead band) for setpoint operations.
The Operate Limit defines the operating threshold, and the second Release
Limit defines the release threshold for the trigger. The trigger thresholds
are specified in primary units.
If you do not want to use hysteresis for the trigger, set the Release Limit
to the same value as the Operate Limit.
Using Binary Triggers
Binary (digital) triggers like digital inputs and relays are tested for
ON/CLOSED or OFF/OPEN status.
In the PM130, the binary events are level-sensitive events. An event is
asserted all the time while the corresponding condition exists.
