Hello, I have been developing a OPC-UA server for 2 months and worked fine with UA expert and some other clients but now i have a problem with Ignition. I can read all the variables names and folders on the server but the value is always null and the status is stale. In the ignition log it says thi…

What version of Ignition are you using? Can you get a Wireshark capture of the OPC UA traffic between Ignition and your server?

I am using Ignition 7.9.7, these are the traffic request and response traces: Frame 550: 139 bytes on wire (1112 bits), 139 bytes captured (1112 bits) on interface 0 Interface id: 0 (enp0s25) Encapsulation type: Ethernet (1) Arrival Time: May 8, 2018 13:53:06.875031796 CEST [Time s…

Nevermind, I’m pretty sure you’re running into this issue. It’s fixed in Milo 0.2.1 but Ignition is currently using 0.2.0. I can build and email you an updated OPC UA module if you’d like. PM me the email address to send it to.

Thanks a lot, Did you sent it? i am checking the e-mail but I have not received it yet

I did, maybe it’s getting filtered… Yep, your email server bounced it back. I’ll have to upload it somewhere.
