Wiring Example
When Connecting the CPU Module via RS485
Wiring example when connecting CPU modules via RS485
We do not recommend connecting the SG line using a shielded cable.
Since the shield of the "FC6A-KC1C external device/O/I connection cable" will be connected to FE (or PE) of the CPU module, one
end of the shield will be grounded when connected to FE (or PE) of the CPU module.
When communication quality is unstable, add terminating resistance matched to the characteristic impedance to both ends of the
cable. Use resistance with a rating of 1/2 W or higher.
