OPCUA Interface - Error in activating session

Ernesto 7 months ago in OPCUA4Unity updated by Support 2 months ago 30

Dear all,

I'm having problems to connect to a remote OPC UA server using the OPCUA Interface Component.

I followed the "Connection troubleshouting" guidelines provided in "/game4automation/Documentation/opcua.html".

Configuring the OPC Server with "No security certificates and passwords" I could connect OPC Watch with the server (see Image):


Image 576


However, when I tried connecting through the Unity OPCUA Interface:


Image 577


I get the following error message:

OPCUA Interface - Error in activating session [BadUnknownResponse]
UnityEngine.Debug:LogError (object)
game4automation.OPCUA_Interface:Connect () (at Assets/game4automation/private/Interfaces/OPCUA4Unity/OPCUA_Interface.cs:179)
game4automation.OPCUA_Interface:EditorImportNodes () (at Assets/game4automation/private/Interfaces/OPCUA4Unity/OPCUA_Interface.cs:246)
game4automation.OPCUAInterfaceEditor:OnInspectorGUI () (at Assets/game4automation/private/Interfaces/OPCUA4Unity/private/Editor/OPCUAInterfaceEditor.cs:20)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)


As it can be seen in the last image, I'm using Unity 2021.3.2f1 Editor with Game4Automation Digital Twin Professional 2020.


Any idea of what I'm missing?


Thank you in advanced.

Hi, I checked. I found an issue with reconnection, that is why I am attaching here a new script. This will be included in next release.

OPCUA_Interface.cs

The disconnect problem and the PLCOutputBool can't be reproduced here on my computer with Simit.

Problems in OPCUA4Unity Output

Janik Tian 6 months ago in OPCUA4Unity updated by Support 6 months ago 4

Servus, I'm using OPAUA Interface for my first Program, but there are some problems with communication when i write int and float format variables in my PLCs.  In Figure 3 and 4 I try to write INT values to "robotArmSuccess" but in OPC Server the corresponding values are not changed. Then I read Demo of OPCUA and modify my Program with the function WriteNodeValue(NodeId, value) , it did not work in PLC Server, according to figure 1 and 2 . Could you please give me some Guidance for this situation?

Driver_Simple script does not accept OPC UA variable nodes

Ernesto 7 months ago in OPCUA4Unity updated 5 months ago 17

Dear developers,

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


I followed the instructions from this tutorial:

Youtube video


The OPCUAInterface is updating the nodes correctly:


Image 582

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).

Image 583

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!

Hi Ernesto,


I am able to connect and to import the signals (even if I am not able to connect to the PLC because I don't have same setup).


Don't know where the problem is. Just for beeing sure I will send you again the latest code of the interface via mail. Please also check in Kepserver if you enabled anonymous login.

OPCUA problems - doesnt Import any In-/Outputs

AndreS2 7 months ago in OPCUA4Unity updated by Support 7 months ago 5

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:

Image 565



You can see the Inputs and Outputs. 

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

Image 566


In the "PLCOutputBool.cs", when changing from

Image 567


to

Image 568

The import finishes with no more errors.

Image 569

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

Image 570


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

Hi,

can you share your PLCSIM-Advanced project (PLCSIMAdvanced 3.0)? Can be a simlified one with just the inputs and outputs.

Thanks
