• If the test is completed with an error, the ERR. LED turns on. If the test is completed with an error, replace the Ethernet
cable and run the test again. If the test is completed with an error again, it may be due to a hardware error in the I/O

function setting switch 1 is set to ON, data link may not be properly performed on modules of other stations.
Set appropriate values both for the IP address/station number setting switch (x16) and the function setting switch 1, and
connect the I/O module to the network.
