Unit Test

Connect P1 and P2 of the I/O module with an Ethernet cable.

Set the IP address/station number setting switches and the function setting switches as follows.
• IP address/station number setting switch (x1): Any position
• IP address/station number setting switch (x16): F
• Function setting switch 1: ON
• Function setting switch 2 to function setting switch 10: Any position
4.
Power on the I/O module.
5.
Unit test begins.
The RUN LED flashes during the unit test.
6.
The RUN LED turns on when the unit test is completed.
• If the test is completed normally, the ERR. LED does not turn on, but remains off.
• 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
module. Please consult your local Mitsubishi representative.
Precautions
If the I/O module is connected to the network while the IP address/station number setting switch (x16) is set to F and the
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.
