7.7. Switching Thresholds
The switching thresholds can be set manually via IO-Link.
Switching points:
The following switching points are calculated on the basis of the measured value during Teach-In:
Hoff
Lon
Hon
Loff
Measurement
Hoff = Hon + Hysteresis
Hon = Hue value + window size
Lon = Hue value – window size (this result can easily become negative)
Loff =
Lon – Hysteresis (this result can easily become negative)
Only the windows size values can be changed with interface. The other values are calculated on the basis of
hysteresis, although hysteresis is not a fixed value itself but rather a calculated value as well.
7.8. Error or Contamination Output
When the pin is configured as an error or a contamination output, the following functions can be selected:
