If bit 15 of C is ON and more than one address contains the same maximum val -
ue, the position of the lowest of the addresses will be output to D+1.
The
number of words within the range (N) is contained in the 3 rightmost digits of
C, which must be BCD between 001 and 999.
When
bit 15 of C is OFF , data within the range is treated as normal binary and
when it is ON the data is treated as signed binary.

Caution If
bit 14 of C is ON, values above #8000 are treated as negative numbers, so the
results will dif fer depending on the specified data type. Be sure that the correct
data type is specified.
Flags ER: Indirectly addressed DM word is non-existent. (Content of : DM word is
not BCD, or the DM area boundary has been exceeded.)
The number of words specified in C is not BCD (000 to 999).

+N–1
for
the address that contains the minimum value and outputs the minimum value
to the destination word (D).
If bit 14 of C is ON, MIN(––) identifies the address of the word containing the
minimum value in D+1. The address is identified differently for the DM area:
1, 2, 3... 1. For
an address in the DM area, the word address is written to D+1. For ex -
ample,
if the address containing the minimum value is DM 01 14, then #01 14
is written in D+1.
2. For
an address in another data area, the number of addresses from the be -
ginning of the search is written to D+1. For example, if the address contain -
ing the minimum value is IR 114 and the first word in the search range is
IR 014, then #0100 is written in D+1.
