ival.i4.v = MINNOM(indata.i1a.r, ierr.i2.r [,units.i1a.r])
Scaling service routine: Obtaining The Unprocessed Tolerance.
ival unprocessed minimum/nominal data from the alarm block.
For the analog alarm block (ANALBL) property, the value
is suitable for processing by PDUDPU or PDUDCU. For the
digital alarm block (DGALBL) property, the value is
a bit pattern mask of defined bits.
indata unprocessed analog or digital alarm block as returned by
a call to DPGET
ierr error code returned as 0 for success
units optional argument in which the units text is returned as 4
ASCII characters in a longword integer field.
(use with FORTRAN CHARACTER*4 via %REF(char)).
The text is one of "MIN ", "NOM " or " " for MINimum
value, NOMinal value, and bit pattern or undefined.
