0
A function that detects the abnormality in the control loop.
・
It detects “PV Variation” per “LoP1” time.
It detects “Loop Abnormality” if the value is less than “PS1.”

Setting “0” will turn the judgment on loop abnormality PV
variation OFF
0
A function that detects the abnormality in the control loop.
If tS1 satisfies the threshold value, the judgment on the following loop disconnection takes place:
・
It detects “PV Variation” per “LoP1” time.
・
It detects “Loop Abnormality” if the value is less than “PS1.”
・
If PS1 = 0, only the judgment on time by LoP1 will be performed. If the time duration in which tS1 satisfies the threshold
exceeds LoP1, then it detects “Loop Abnormality.”
