Check the conduction of the communication wiring.
Check the terminal block connected.
Check the value of the terminal resistance with a tester.
Change it to the specified wiring length.
Replace with the normal digital input / output relay interface and check that
the communication is available.
Replace with the normal controller and check that the communication is
available.
Check the waveform between RS-485 communication wiring A and B.
If noise is superposed, identify the noise source and remove it.
Change it to the specified communication cable.
1.Check the address switch setting of the digital input / output relay
interface and the setting in the setting file.
