RnCPU RnENCPU
(Process) (Redundant)
• TO(P): These instructions write the n points of data from the specified device to the buffer memory in the module/host CPU
module.
• DTO(P): These instructions write the n2 points of data from the specified device to the buffer memory in the module/host
CPU module.

Operand Description
(U/H) Start I/O number (first three digits in four-digit
hexadecimal representation) of a module or CPU
module
(s1) Start address of buffer memory or CPU built-in
memory to which data is to be written
(s2) TO(P) Write data or the start device where the write
data is stored
DTO(P)
(n) Number of write data
EN Execution condition
ENO Execution result
*1 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
