Ml1100 Series A

trying to commission a ML1100 series A plc.
I read other posts about series A only allowing 1 ethernet connection.

I can ping plc and browse to CPU with web browser. oPC-Ua micrologix driver just bounces between connected and disconnected.
What port is the driver using?

I tried a trial kepware connection to this plc using port 44818 and can connect.
Ignition V7.6.2

Flashed ML1100 to series B V14 and all is good, but customer gave me grief as to how Ignition was only hmi/scada with issues connecting to this plc.
