Hysteresis_DINT (FB)¶

FUNCTION_BLOCK Hysteresis_DINT

This function block will set the output variable to TRUE, if the integral value \(x \in \mathbb{Z}\)
is smaller than an integral lower bound \(x_{u} \in \mathbb{Z}\)
It will set the Boolean output variable to FALSE, if the input value \(x\) exceeds the integral upper bound \(x_{o} \in \mathbb{Z}\).
If \(x\) lies between the lower and upper bound, the value of the output will rest unchanged by the module.

InOut:

Scope	Name	Type	Comment
Input	`diValue`	`DINT`	input value \(x \in \mathbb{Z}\)
	`diLimitPos`	`DINT`	upper bound \(x_{o} \in \mathbb{Z}\)
	`diLimitNeg`	`DINT`	lower bound \(x_{u} \in \mathbb{Z}\)
Output	`xOut`	`BOOL`	`FALSE`: If \(x > x_{o} \land x_{u} < x_{o}\) `TRUE`: If \(x < x_{u} \land x_{u} < x_{o}\) “`xOut`” else
