ACCESS VIA NETWORK MODULES
5.4 CC-Link IE Controller Network Module Access Function
The CC-Link IE controller network module access function allows access to each station,
programmable controller CPU on another station, or a C Controller module connected to
the CC-Link IE controller network via a CC-Link IE controller network module.
In a multiple CPU system configuration, access cannot be made via a CC-Link IE
controller network module controlled by another CPU.
To create user programs of the C Controller module, use MELSEC data link functions or
bus interface functions.
