(2)I/O number assignment of Motion CPU control module

Mitsubishi recommends that I/O No. assignment be set as common consecutive No. throughout all CPUs.

However, the I/O number of the input modules, output modules and input/output composite modules controlled with the Motion CPU can also be set regardless as the I/O number of PLC CPU.

(I/O number of the Motion CPU control modules is indicated as PX/PY.) I/O number of the Motion CPU control modules cannot be assigned by I/O assignment settings of PLC CPU.

(3) Setting of the Motion CPU control modules by the PLC CPU

Follow the table below when Motion CPU control modules are set in I/O Assignment Settings of the PLC CPU. (The PLC CPU handles the Q172DLX, Q172DEX and Q173DPX as intelligent function modules having 32 occupied points.) Type and number of points may be left unset.
