Out-Of-Group I/O Fetch - Mitsubishi Electric MELSEC iQ-R C R12CCPU-V User Manual

8.1

Out-of-Group I/O Fetch

In a multiple CPU system, the access range of the controlled module is different from that of the non-controlled module. The
out-of-group I/O fetch function enables data which cannot be accessed to be imported. However, data cannot be imported
from the module that is an inter-module synchronization target.
Accessing controlled module
The access range to the controlled module of the CPU module is the same as that of the single CPU system. I/O refresh for
the controlled module or read from/write to the buffer memory of an intelligent function module is enabled.
Accessing non-controlled module
Access to the non-controlled module of the CPU module is limited to reading the buffer memory of the intelligent function
module. However, the ON/OFF data of output (Y) of the non-controlled module can be imported by "I/O Setting Outside
Group".
