TO, TOP, DTO, DTOP
DTO
(1) Writes device data of words to (n3×2) to the CPU shared memory address specified by n2 of the host CPU module or
later address.
When a constant is specified to , writes the same data (value specified to ) to the area of (n3×2) words from the
specified CPU shared memory.
(2) No processing is performed when the number of write points is 0.
(3) The number of data that can be written varies depending on the target CPU module.
Writing data to CPU shared memory can be performed using the intelligent function module device.
For intelligent function module device, refer to the QnUCPU User's Manual (Function Explanation, Program Fundamentals)
or Qn(H)/QnPH/QnPRHCPU User's Manual (Function Explanation, Program Fundamentals).
Operation Error
In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
