Macro interface inputs (#1000 to #1035, #1200 to #1295) : PLC → NC
The status of the interface input signals can be ascertained by reading out the values of variable
numbers #1000 to #1035, #1200 to #1295. A variable value which has been read out can be only
one of 2 values: 1 or 0 (1: contact closed, 0: contact open). All the input signals from #1000 to
#1031 can be read at once by reading out the value of variable number #1032.
Similarly, the input signals #1200 to #1231, #1232 to #1263, and #1264 to #1295 can be read by
reading the values of the variable numbers #1033 to #1035.
Variable numbers #1000 to #1035, #1200 to #1295 are for readout only, and cannot be placed in
the left side member of their arithmetic formula. Input here refers to input to the control unit.
To use the macro interface function by part system, set the bit selection parameter "#6454/bit0".
Refer to (2) for the signals provided for each part system.
