Appendix 3 Compatibility With Multiple Cpu Systems; When Rcpu Is Configured In The Multiple Cpu System - Mitsubishi Electric MELSEC IQ-R series Reference Manual

Appendix 3
This section explains data communication using MC protocol when CPU modules are configured in the multiple CPU system.
Another station can be accessed whether the control CPU
of the module acting as a relay is the same or different.

By setting routing parameters (communication route) in advance, accessing programmable controllers in the
following network systems are available.
• CC-Link IE Controller Network
• CC-Link IE Field Network
• MELSECNET/H
• MELSECNET/10
• Ethernet
Up to 8 target networks (relay stations: 7 stations) can be accessed.

When RCPU is configured in the multiple CPU system

When using C24/E71 in the multiple CPU system of RCPU, refer to the following manual.
 MELSEC iQ-R Module Configuration Manual
Accessing multiple CPU system on connected station (host station)
■Accessing multiple CPU system on connected station (host station) from external devices
Control CPU (set with Engineering tool) and non-control CPU of C24 can be accessed.
The usable commands vary depending on the access target RCPU (control CPU, non-control CPU).
Accessing multiple CPU system on other station
■Accessing multiple CPU system on the other station (access station)
Control CPU and non-control CPU of the network module connected to the relay station can be accessed.
The usable command vary depending on the access target RCPU (control CPU, non-control CPU).
The modules which can be accessed to other stations via network are as follows.
• CC-Link IE, MELSECNET/H, MELSECNET/10 Network Module
• C24
• E71
