LimitAlarm_DINT (FB)¶

FUNCTION_BLOCK LimitAlarm_DINT

This function block checks whether an integral value \(x \in \mathbb{Z}\) lies between an integral lower bound \(x_{u} \in \mathbb{Z}\) and an integral upper bound \(x_{o} \in \mathbb{Z}\).

The output value will be set according to the result.

InOut:

Scope	Name	Type	Comment
Input	`diValue`	`DINT`	value \(x \in \mathbb{Z}\) to be tested
	`diLimitPos`	`DINT`	upper bound \(x_{o} \in \mathbb{Z}\)
	`diLimitNeg`	`DINT`	lower bound \(x_{u} \in \mathbb{Z}\)
Output	`xExceedsPos`	`BOOL`	`TRUE`: If \(x > x_{o}\) `FALSE`: Else
	`xExceedsNeg`	`BOOL`	`TRUE`: If \(x < x_{u}\) `FALSE`: Else
	`xInLimits`	`BOOL`	`TRUE`: If \(x_{u} \leq x \leq x_{u}\) `FALSE`: Else, also in the atypical case \(x_{o} < x_{u}\)
