3.1.3 Input/output numbers
With the multi-CPU system, the slots equivalent to the number of CPUs set in the PC
parameter multi-CPU setting are occupied by the Q-PLC CPU/Q motion CPU.
The input/output numbers are assigned sequentially to the right with the input/output
unit and intelligent function unit (mounted at the right slot occupied by the Q-PLC CPU/
Q motion CPU) assigned as "0H".
Q-PLC CPU: When the number of PLC CPUs is set to "2 units"
0 1 2 3 4 5 6 7
Input/output No.: 0H

Q-PLC CP
Q motion CP
The Q motion CPU I/O No. is independent of that of Q-PLC CPU. It is the I/O No. set
by Q motion CPU system setting. (The I/O No. of a unit controlled by the Q motion
CPU is indicated as "PX/PY".)
Note that the I/O No. of a Q motion CPU control unit assigned in "I/O assignment of Q-
PLC" is invalid even if it is assigned.
It is basically recommended to execute such setting that it is serial in all CPUs.

When assigning the Q-PLC CPU I/O, set the Q motion CPU control unit as shown in
the following table. (The Q172LX and Q172EX are treated to occupy the 32 intelligent
function unit points in the Q-PLC CPU.)
