Example

Configuring a user value range:

main()
{
  dpSet("TestDP_1.element:_u_range.._type",
  DPCONFIG_USER_RANGECHECK,
  "TestDP_1.element:_u_range.5._type",
  DPDETAIL_RANGETYPE_MINMAX,
  "TestDP_1.element:_u_range.5._max", 50,
  "TestDP_1.element:_u_range.5._min", 2,
  "TestDP_1.element:_u_range.5._incl_max", TRUE,
  "TestDP_1.element:_u_range.5._incl_min", TRUE);
}

The user value range for authorization level 5 lies between 50 (Max.) and 2 (Min.) including the limits. Further details to the config "_u_range" you will find in the chapter Module PARA - _u_range (user value range).
