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.

Description When
the execution condition is OFF
,
MIN(––) is not executed. When the execu

tion
condition is ON, MIN(––) searches the range of
memory from R
1
to R
1
+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.
