Hi Experts,

When customer use the modified eds files, and run EIP demo again, they use wireShark to say "connection failure" below:

Customer also use the same modified eds files to compared competitors MD500P_EIP and LP-AM243.

-MD500P_EIP

-LP-AM243

The customer capture the Wireshark on LP-AM243 below.

the modified eds files as below:

You can fine the below picture, when the PLC scanner sent the step4 data- forward open request, the MD500P_EIP can response the ”success：connection manager“, but our LP-AM243 response the ”connection failure“. So it stuck at Step 5 forward open response. We want to know how to modify the EIP demo code? Or Any suggestion here? Thanks.
