Note The rate of change is calculated every second (and not just once during the
comparison time interval) so that even minute changes in the process value
are detected.
An hysteresis can be set for the process value (or instantaneous value) alarm
and the rate-of-change alarm. The operation is as shown in the following dia-
gram.
This function is supported by the following Units:
