PK Controller Not Communicating with device over Ethernet/IP

I am trying to integrate a device using PK100 Controller via Ethernet/IP using Class 1 Implicit.

My DeltaV Version is v14.FP2 Build 7944. My PK100 controller firmware was at SwRev 14.3.0.6843.xr. I was able to communicate with my device at this firmware revision.

I recently upgraded the PK100 controller firmware to SwRev 14.5.1.7944.xr. After the firmware upgrade, I am no longer able to communicate with my device even though all the IP addresses, assembly instance configuration and signal configuration is the same.

Is there any additional step required after this firmware upgrade?

    In reply to Chaitanya Adkar:

    Thanks for the follow-up. This is very interesting that recreating the PDT/LDT recovered the communications. There are some devices that only allow a single owner and I wonder if that might have come into play here. During the act of upgrading, I could see a possibility that the device got confused and thought it was now talking to something different due to some change with the way the PK works. However, it's hard to speculate and we will probably never know the true reason.

    Glad you got it working!
