@meverett without knowing exactly what the problem is it will be hard for us to diagnose/fix the bug. Can you provide a pcap file from WireShark for the communication for a few polls? It is either the read request for the data points OR the connection request to initialize the connection.
Once I have some time I will take a look. I will admit it has been some time since I've decomposed any ABeIP packets but hopefully it will come back to me quickly!
