Anonymous connection works fine, but when using a username and password, the console doesn't show any errors in creating the connection, but I am not able to read or write to nodes. Also the server doesn't acknowledge the connection. Even when using application certificates the connection doesn't work properly. Using OPC Watch or UaExpert I can easily connect to the server with the username and password.

I have this problem when I try connecting Prosys OPC UA server simulator: OPCUA Interface - Error in opening secure channel [BadEncodingLimitsExceeded]

I can connect with OPC watch like in game4automation documentation. Whats wrong?

Hi, we tried to create a simulation with G4A and OPCUA4Unity together with a Rexroth ctrlX as OPC UA server. But unfortunate the client doesn't want to connect. The ctrlX offers only secure Endpoints but the OPCUA4Unity doesn't accepts them. Is there a reason for that or could we configure the client to accept this?

I just got started with OPCUA. I have a Siemens S7-1500 connected via ethernet cable. I can connect to it and read the nodes, but I can't import nodes via OPCUA Interface. I also did a test with GetAllSubnodes(topnodeid) and it found all 9 nodes it should.

My biggest issue however is using the data. If I use the recommended subscribe method, it is simply too slow (updates around 2 times a second). If I use the direct method I get the update speed, but fps tanks to unbearable with just 1 node.

How can I get better update rates with the delegate/subscribe method? (or any for that matter)

Unityversion: 2020.3.12f1 LTS

I watched your video（ABB RobotStudio with Unity and Game4Automation）it show you use OPCUA to connect，I want to use OPCUA too，but I don't how to do it，could you make a video show me how to do it？Thanks very much！

Hi everyone!

Someone with experience connecting KepserverEX6 and OPCUA Interface of Game4Automation, and also writing and reading tags between them.

Regards!

Our physical machine is made up of multiple OPCUA servers. 

In our Unity scene we have several OPCUA_Interface objects to connect to each server and a OPCUA Node connected to each interface.

If we use Read Value on the nodes we get the values we expect, however if we use the subscribe option we get the same value across all interfaces as if they are being overwritten somehow. We can get around it by using Read Value but it seems to come with a heavy performance cost. 

Is this a bug or is there another way to set this up?

Many thanks

Für ein Projekt versuche ich die Nodes vom C++ Test Server von Unified Automation zu importieren. Die Verbindung funktioniert und OPC Watch zeigt den Server mit allen Nodes korrekt an. Wenn ich aber "Import Nodes" in Unity drücke, dann kommt eine Exception:

In den Einstellungen habe ich eigentlich nichts verändert:

Ich bitte um Hilfe.

OPCUA4Unity接口是否可以部署在Hololens 2上？

Hi,

I'm currently learning how to use game4Automation for a project and I'd like to read custom data types from the OPCUA server.

In the demonstration server, there is a Work Order variable (ns2, s=Demo.WorkOrder.WorkOrderVariable) which contains a StatusComments array recognized as an ExtensionMethod by game4automation. This array can be read as a byte[] array, but is there any better way to do this? It is pretty messy and not easy at all to work with.

Thanks for your answer!
