ACCESS VIA NETWORK MODULES
5.2 CC-Link Module Access Function
(1) The CC-Link module access function
This function allows access to each station, programmable controller CPU on another
station, or C Controller module that is connected to CC-Link via CC-Link modules.
In a multiple CPU system, access cannot be made via a CC-Link module controlled
by another CPU.
To create user programs of the C Controller module, use MELSEC data link functions
or bus interface functions.
For the Q06CCPU-V-B, MELSEC data link functions cannot be used.
When the Q06CCPU-V-B is used, use cyclic transmission for access to a CPU
module on another station.
Remark
For the bus interface functions and MELSEC data link functions, refer to the
following.

<Example>
C Controller module
/* Reads device data of the other station programmable controller CPU */
ret = mdReceive(path, stno, devtyp, devno, size, data);
/* Writes data to its own station RY and outputs it to the remote I/O module */

Device data
1) Reads the device data of the other station programmable
controller CPU to the C Controller module via the CC-
Link module.
2) Writes data to RY of the CC-Link module itself and outputs
it to the remote I/O module.
