WindowCheck
This function block sets the InWindiow output high if the InputValue is within +/- (Window/2) of the
TargetValue. This function is useful when making a comparison that only relies on the InputValue to be close to
the Target, but an exact match is not required.
Parameters
* Parameter Data
Type Description
VAR_INPUT Default
B Enable BOOL
The function will continue to execute while enable is
held high.
FALSE
V InputValue LREAL The data to be tested against the TargetValue LREAL#0.0
V TargetValue LREAL The desired data to be compared against. LREAL#0.0
V Window LREAL
This amount will be divided in two. The InputValue
must fall within half the window distance of the
TargetValue for the InWindow output to go high.
Window must be greater than zero.
LREAL#0.0
VAR_OUTPUT
B Valid BOOL Indicates that the outputs of the function are valid.
V InWindow BOOL
Indicates that the InputValue is within the TargetValue +/-
(Window/2) inclusive.
B Error BOOL
Set high if error has occurred during the execution of the function
block. This output is cleared when 'Execute' or 'Enable' goes low.
B ErrorID UINT
If Error is true, this output provides the Error ID. This output is reset
when 'Execute' or 'Enable' goes low.
