connected via a crossed-over Ethernet cable.
1.2. Check the communication status of the front port via the LHMI in
Main
menu/Test/Function status/Communication/DOSFRNT:1/Outputs
.
Check that the
LINKUP
value is 1, that is, the communication is working.
When the value is 0, there is no communication link.
2.
Check the communication status of the rear port X1 via the LHMI in
Main menu/
Tests/Function status/Communication/DOSLAN1:1/Outputs
