VLHI - APMonitor Option
Type: Floating Point, Input Default Value: 1.0e20 Description: Upper validity limit
VLHI is the upper validity limit for a measured value. Validity limits are one way to protect an application against bad measurements. This gross error detection relies on a combination of change values and absolute limits to determine when a measurement should be rejected. If VLHI is exceeded, the measured value is placed at VLHI or the maximum move allowed by VDVL when VLACTION=1. If VLACTION=0, there is no change in the measured value when a limit (VDVL, VLHI, VLLO) is exceeded.
