(1) Access example
Using the logical station No."65", access can be made from a MELSECNET/H module
controlled by the C Controller module to CPU No.4 via another MELSECNET/H
module (controlled by CPU No.2, network No.1).
From the Device monitor utility or user program (MELSEC data link function), access
can be made to CPU No.4 by opening Channel No.51 and specifying station No.65.
* 1 If the CPU No.4 cannot configure the multiple CPU system, access using the logical station
No.cannot be made to the CPU No.4.
The target setting for the above access is shown below.
