USER MACRO INTERFACE
—
INPUT FOR EACH PART
SYSTEM #1032 TO 1035
[Function]
This interface is used between the user PLC and user macro program.
The state of the interface input signal can be seen by reading the values for variables #1000 to
#1035 and #1200 to #1295.
Only 1 or 0 (1 = contact closed, 0 = contact open) is read as variable value.
"Input" here refers to input from the PLC to NC.
[Operation]
All input signals from #1000 to #1031 can be read at once on the user macro side by reading the
variable #1032 value. Similarly, the #1200 to #1231, #1232 to #1263 and #1264 to #1295 input
signals can be read by reading the variable #1033 to #1035 values.
#1000 to #1035 and #1200 to #1295 are read-only, and cannot be set on the left side of a
calculation expression.
Bit selection parameter (#6454/bit0) must be set to use the macro interface function for each part
system.
Refer to R24, R25 (#1032: PLC → controller) and R124, 125 (#1132: controller → PLC) for details
on the user macro interface signals common for the part system.
