Mitsubishi Electric MELSEC iQ-R Series - Writing Device Data to Another CPU Module

1408
12 MULTIPLE CPU DEDICATED INSTRUCTIONS
12.1 Another CPU Module Access Instructions
Writing device data to another CPU module
D(P).DDWR, M(P).DDWR
• D(P).DDWR
• M(P).DDWR
These instructions write device data to another CPU module in a multiple CPU system.
■Execution condition
Setting data
■Description, range, data type
*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.
The RnENCPU with firmware version "25" or later supports these instructions. (Use an engineering tool with version "1.032J" or later.)
