Configuring in "Hysteresis" mode

The output status changes when a threshold is reached:
• When increasing the process input value, the output status changes when the high threshold is reached.
• When decreasing the process input value, the output status changes when the low threshold is reached.

Low High Process input
Fig. 91: Hysteresis mode
PV: Choose the process input associated with the output.
LOW: Choose the value of the low switching threshold of the output.
HIGH: Choose the value of the high switching threshold of the output.
INVERT: Invert the output or not.
DELAY: Choose the value of the delay time before switching for each digital output. This is valid for both
output thresholds. Switching is only done if one of the thresholds, high or low (functions "High" or "Low"), is
exceeded for a duration longer than this delay time.
9.26.3

Configuring in "Window" mode

The output status changes as soon as any threshold (low or high) is reached.
