[jira] [Created] (PLC4X-353) Issue with create PCCC connection problem
susliks created PLC4X-353:
-----------------------------
Summary: Issue with create PCCC connection problem
Key: PLC4X-353
URL: https://issues.apache.org/jira/browse/PLC4X-353
Project: Apache PLC4X
Issue Type: Bug
Components: Driver-Ethernet/IP
Affects Versions: 0.9.1
Reporter: susliks
Attachments: EtherNetIP_PCCC_CM.pcapng, decodeerror.png
Hello,I want to register PCCC connection manager after registering the session of ethernet/ip.But I cant receive the response with PCCC connection manager.
I create the pccc cm request in EtherNet/IP connectResponse's handle just like S7Driver.

Now I find some problem but I dont know what cause it.In Plc4xNetttyWarpper decode function，It cant receive the second response.Wireshark captured the correct packet.
Here is my driver code
