USER MACRO INTERFACE
OUTPUT FOR EACH PART

SYSTEM
#1132 to 1135
[Function]
This interface is used between the user PLC and user macro program.
The interface output signal can be sent by substituting a value in the variables #1100 to #1135 and
#1300 to #1395. Only 0 and 1 are used as the output signals.
Output here refers to outputting from the NC to the PLC.
[Operation]
When a value is substituted in variable #1132 with the user macro, all output numbers between
#1100 and #1131 are sent out at once. These values can be referred to with the user PLC. When a
value is substituted in variables #1133 to #1135, the #1300 to #1331, #1332 to #1363 and #1364 to
#1395 output signals can be sent.
The status of the writing and output signals can be read to offset the #1100 to #1135 and #1300 to
#1395 output signals (2
The bit selection parameter (#6454/bit0) must be set to use the macro interface function for each
part system.
Refer to R24, 25 (#1032: PLC → controller) and R124, 125 (#1132: controller → PLC) for details on
the user macro interface signals common for the part systems.
(Note 1) The last system variable #1100 to #1135 values sent are saved as 1 or 0.
(These are not cleared with reset.)
(Note 2) The following applies when any number other than 1 or 0 is substituted into #1100 to
#1131.
<Blank> is treated as 0.
Any number other than <Blank> or 0 is treated as 1.
Any value less than 0.00000001 is indefinite.
