Communication With Dedicated Instructions; Writing/Reading Of Device Data From Qcpu To Motion Cpu - Mitsubishi Electric MELSEC Q Series User Manual

4.3 Communication with Dedicated Instructions

4.3.1 Writing/reading of device data from QCPU to Motion CPU

The QCPU can write/read device data to/from the Motion CPU with the multiple CPU transmission dedicated
instruction and multiple CPU high-speed transmission dedicated instruction.
(Writing/reading from the Motion CPU to other CPU modules including the Motion CPU is not allowed.)
(Example) Using the S.DDWR instruction
The QCPU device data can be written to the Motion CPU devices.
(1) Multiple CPU transmission dedicated instruction
The QCPU can write/read device data to/from the Q172CPUN(-T), Q173CPUN(-T), Q172HCPU(-T), and
Q173HCPU(-T) with the multiple CPU transmission dedicated instruction shown on Table4.15.
