Example
Configuring the config "_pv_range" is shown below:
main()
{
dpSet("TestDP_1.element:_pv_range.._type",
DPCONFIG_MINMAX_PVSS_RANGECHECK,
"TestDP_1.element:_pv_range.._min", 10,
"TestDP_1.element:_pv_range.._max", 30,
"TestDP_1.element:_pv_range.._neg", TRUE,
"TestDP_1.element:_pv_range.._incl_min", TRUE,
"TestDP_1.element:_pv_range.._incl_max", TRUE,
"TestDP_1.element:_pv_range.._ignor_inv", FALSE);
//
dpSet("TestDP_1.element:_pv_range.._match, "Text");
//
dpSet("TestDP_1.element:_pv_range.._set, 25, 23);
}The range is between 10 and 30 including the limits and negated, i.e. values outside the specified value range are valid (inverted value range). Further details to the config "_pv_range" you will find in the chapter Module PARA - _pv_range (WinCC OA value range).
