> 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
> Priority: Major
> 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.
