Inspection procedure / Diagnosis
Select the online mode on LA NWM.
Include the controller IP address in the
scanning range on LA NWM.
Set the computer IP address and subnet
mask as well as the controller IP address
as indicated in the LA NWM video
tutorial.
Plug and secure a CAT5e U/FTP cable into
the L-NET IN connector on the controller
and the network connector on the device
preceding the controller in the network
chain (computer, L-NET OUT connector on
another controller, or Ethernet switch).
Do the same for each cable of the network
chain from the controller to the computer.
Unplug the CAT5e U/FTP cable and plug it
again on both sides. Do the same for each
cable of the network chain from the
controller to the computer.
Use straight-through Ethernet cables of
CAT5e U/FTP category (or higher) and of
100 m/328 ft maximum length.
If an Ethernet switch is used and the auto
MDI/MDIX functionality is not available on
it, use a crossover cable between the
switch and each controller.
Replace all damaged CAT5e U/FTP cables of
the network chain from the controller to
the computer.
Disconnect the software client.
Restart the controller.
