13.8 Motion CPU Device Access
(1) Motion CPU device access
From a user program of the C Controller module, data can be written to and read from
Motion CPU's devices.
Use the bus interface functions when creating a user program of the C Controller
module.
POINT
To apply this function to the Q172DCPU or Q173DCPU, the C Controller module
must be the Q12DCCPU-V.
Remark
For the bus interface functions, refer to the following.
