Writing Device Data To Another Cpu Module - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Writing device data to another CPU module

D(P).DDWR, M(P).DDWR
• D(P).DDWR
RnPCPU
RnCPU RnENCPU
(Process)
The RnENCPU with firmware version "25" or later supports these instructions. (Use an engineering tool with version "1.032J" or later.)
• M(P).DDWR
RnPCPU
RnCPU RnENCPU
(Process)
The RnENCPU with firmware version "25" or later supports these instructions. (Use an engineering tool with version "1.032J" or later.)
These instructions write device data to another CPU module in a multiple CPU system.

Operand Description
(U/H) Start I/O number (first three digits in
four-digit hexadecimal representation)
of another CPU module
(s1) Start device of host CPU module
where the control data is stored
(s2) Start device of host CPU module
where the write data is stored
(d1) Start device of another CPU module
for storing the written data
(d2) Completion device
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.
