9.1 Writing to the CPU Shared Memory of Host CPU
9.1.2 Writing to host station CPU shared memory (TO(P), DTO(P))
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).
