Motion CPU Device Access

(1) Motion CPU device access
C Controller module
/* Write to Motion CPU device */
ret = QBF_MotionDDWR(path, sCpuNo, sDeType, ulDevNo,
ulSize, pusDataBuf, ulBufSize, ulTimeout);
/* Read from Motion CPU device */
ret = QBF_MotionDDRD(path, sCpuNo, sDeType, ulDevNo,
ulSize, pusDataBuf, ulBufSize, ulTimeout);
POINT
Remark
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.
Figure 13.35 Motion CPU device access
To apply this function to the Q172DCPU or Q173DCPU, the C Controller module
must be the Q12DCCPU-V.
For the bus interface functions, refer to the following.
