OPC Server Connected, OPC Client Bad Quality

Ignition
,
1

I have my Ignition OPC UA server connected via the loopback 127.0.0.1 and it shows “Connected”

I am connected to a Device (PLC) at address 192.168.100.101 (this is NAT’d from 192.168.1.101 if that matters).

My tags are good quality in the kepware OPC client as connected through Kepserver (as a test) but through the OPC UA Sever, the quality is bad on its OPC client.

Question

Are there any advanced settings I can tweak to get the OPC Client to read Good Quality tags?

If you are using Ignition's loopback connection, then you are using Ignition's native drivers. Each driver has its own quirks and requirements as to how the PLC connection needs to work. Especially if there might be local firewalls involved.
