Set the secondary control loop anomaly PV change threshold.
The function is to detect an abnormality in the control loop.
When the time satisfying threshold of TS2 or MS2 exceeds LOP2, the loop abnormality is determined as
detected.
For details, see section “Loop abnormality function” on pages 5-38 and 39.
- The control loop anomaly PV change threshold is judged at each “LoP2” time.
A loop abnormality is determined if each change threshold is judged to be equal to or below “PS2.”
- When [PS2 = 0] is true, only time judgment is executed using LOP2.
When the time satisfying threshold of TS2 or MS2 exceeds LOP2, the loop abnormality is determined as detected.
