(3)Network configuration via the RS-422/485

<Example 1>

<Example 2>

(a)It can access the other CPU via the RS-422/485 from the programming software packages (GX Developer, MT Developer, etc.) of the personal computer connected with the CPU or serial communication module in USB/RS-232.

(b)The access range of above (1) is only the CPU on the RS-422/485 which a system connects it to, and it can select RS-422/485 network to connect by specifying the I/O No. of the C24 module.
