Hello All,

I want to connect KTP900 mobile panel to PLC via mobile panel connection box(6AV21252AE130AX0 via Profinet cable.

Here we have 8 core profinet cable (6XV1878-2A ) and connector ( 6GK1901 1BB11 2AE0 ). Other side in connection box is only 4 core available. 

from the Link I have seen the details of pin configuration of IE FC RJ45 Plug 4x2. 

How do i connect box to this ?

1->3, 2->1, 3->6, 4->2 is it ok ?

Update--

After modifying the connection, it's working now..
