Cip Path Destination Unknown

Hi,

i just wantet to throw a look at the Communication between my NXSB100 Evaluation board (loaded with ExampleCode for the Ethernet/IP-Stack V2.0.10) and a Rockwell CompactLogix L32E PLC.
But Evrytime the PLC sends a Forward-Open CIP-Message the Board answers that the Path destination is unknown. In http://www.automationdirect.com/static/manuals/eauserm/appxa.pdf i read that this Answer means: "The path is referencing an object class, instance or structure element that is not known or is not contained in the processing node." Does that mean that the Ethernet/IP-Stack V2.0.10 does not support the Forward Open-Message?

Thanks for your help!

Hello,

for the communication the correct connection end points have to be used. For the input assembly we used the connection end point 101 and for the output assembly we use the connection end point 100.

A valid configuration you can see at the screen shot. The first 4 bytes of the input data are a run/idle header.
