Dear developers,

I was trying to connect a custom Game4Automation Scene to a PLC through OPCUA Interface.

I followed the instructions from this tutorial:

The OPCUAInterface is updating the nodes correctly:

However, when I tried to link a bool variable node from the OPCUAInterface to the Driver_Simple interface dragging it and droping it into the forward variable, it wasn't accepted (the forbiden symbol appeared).

If I use the PLC signal component I'm able to link the component without problems.

I'm using Unity 2021.3.2f1 Editor and the game4automation-Professional-2019.13 package (OPCUAInterface is not working in the latest version of G4A, see https://forum.game4automation.com/en/communities/1/topics/376-opcua-interface-error-in-activating-session).

Any idea of what am I doing wrong?

Thank you in advance!

See the connection via OPCwatch

When I try to import the nodes into UNITY see the errors. And I already tried ANONYMOUS SECURITUY POLICY 0.1 AND 2.

Hey there,

first of all - the example Project provided with the Unified Automation OPCUA Server is working fine. 

Im using the latest Release of G4A which is 2020.16-beta-1123 and Unity Version 2020.3.19

The PLC is created in TIA Portal v17 which sends it to PLCSimAdvanced v4.0.

(Yes(!) i know i could use the PLCSimAdvanced Interface, but for now i have to stick to the OPCUA Interface)

This is what OPC Watch looks like when connected to my PLC which has an OPCUA Server:

You can see the Inputs and Outputs. 

When trying to import these Nodes into Unity with the G4A Framework im getting

In the "PLCOutputBool.cs", when changing from

to

The import finishes with no more errors.

But now looking into Unitys Hierarchy, no In-/Outputs where generated.(No Dropdown available at the Input & Ouput Gameobject)

Even then whole "PLC_1" Node is missing in Unity.

Hello. I have setup an OPCUA Client without issue on several versions of Unity (2019.4.18f1, 2020.3.25f1) with game4automation 2020.13. 

I now seem to have an issue Importing array nodes after an update to game4automation 2020.15. 

The nodes import, but the arrays are only a single gameobject without a list of value, instead of a hierarchy array of game objects that it does with 2020.13. 

Is this a known issue, or does it work differently with arrays now? Possibly because of the OPCUA change in 2020.14?

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!
