Note:
The interface input and output signals of
a. and b, may not be installed. Follow the
specifications of the machine tool builder.
The following paragraphs describe the de-
tails of the variables mentioned above.
a. Intervace Input Signals ( #1000 Through #1015,
#1032)~
i. When one of the system variables, #1000
through #1015, is specified to the right-hand
side of an operational expression, the on/off
state of each of user–macro–dedicated 16-point
input signals is read,
The relationships between
the input signals and the system variables are as
shown below.

Each read variable is 1, 0 or O. 0 when the asso-
ciated contact is
“closed” or “open” respectively,
regardless of the unit system of the machine.
ii.
When system variable #l 032 is designated,
the input signals (UIO through U115) that consist
of 16 points (16 bits) are collectively read as a
decimal positive value.
#1032 = \5# [1000 + i] * 2i
i =0
Sample Program
IF [#1015 EQ O
1 GO TO 100;
Bit 215 (U115) is read and, if it is “O,” a branch
is made to sequence number N1OO.
#130 = #1032 AND 255
Bits 2° through 27 (UIO through U17) are collec-
tively read to be stored in common variable #130
as a decimal positive value.
Note:
System variables #1000 through #1032 can-
not be placed to the left-hand side of operational
expressions.
