The logic value output with output “OUT1” depends on the value of the active measurement
as well as the parameterized “Hysteresis”.
The entered “Hysteresis” must be in the range from 0.1 ... 6550.0 [...].
Assuming a measured value characteristic starts below “Threshold x”, switch on
(“O
UTx” = “1”) occurs when the value is > the parameterized value for “Threshold x”.
Subsequent switch off (“O
UTx” = “0”) then only occurs on an underrange of parameterized
“Threshold x” - “Hysteresis”.
