14.8 Motion CPU Device Access
(1) Motion CPU device access
This function allows data writing/reading from the user program of the C Controller
module to the Motion CPU devices.
Use the bus interface functions to create the user program of the C Controller module.
(2) Functions
The following indicates the functions used for the Motion CPU device access.
Remark
Refer to Chapter 10 for details of the bus interface functions.
Figure 14.19 Motion CPU device access

Function name Function
QBF_MotionDDWR
Writes data to the Motion CPU device.
(Equivalent to the S(P).DDWR instruction of the programmable
controller CPU)
QBF_MotionDDRD
Reads data from the Motion CPU device.
(Equivalent to the S(P).DDRD instruction of the programmable
controller CPU)
