ChkRange
The ChkRange instruction determines if the value of a variable is within the valid range of the range
type specification.
* If you omit the input parameter, the default value is not applied. A building error will occur.
The ChkRange instruction determines if the value of variable to check In is within the valid range of the
range specification variable Val. If the value is within the valid range, check result Out is TRUE. If the
value is not within the valid range, check result Out is FALSE.
You can define the range type specification for integer variables (USINT, UINT, UDINT, ULINT, SINT,
INT, DINT, and LINT).
