MATH.Hysteresis_DINT (FB)

(CAA_Mathematics.library)

This function block will set the Boolean output variable to TRUE, if the integral input value is smaller than an integral lower bound ; it will set the Boolean output variable to FALSE, if the input value exceeds the integral upper bound If lies between the lower and the upper bound, the value of the output variable will rest unchanged by the module.

Input:

diValue	DINT	input value
diLimitPos	DINT	upper bound
diLimitNeg	DINT	lower bound

Output:

xOut

BOOL

Boolean output variable:

FALSE, if and

TRUE, if and

xOut else
