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.

Ich habe eine weile mit eine anderen Simulation System gearbeitet. Daher folgende Fragen

Kann man in Game4Automation sich eine Bibliothek anlegen und sich  die Erstellung einer Szene (fuer Kunden) automatisieren.

Bei dem anderen System kann via einer I/O Liste und einen externen Tool Marcos ausgewählt  und die Verlinkung zu diesen erzeugt werden.

is there a sensor type encoder ?

Hello,

A small time ago we had a conversation about adding bytes into the device mapping of ABB, now i needs words (16bits). 

We are trying to get the Word option to work as well, we have changed the code to the following:

Only thing we are not sure about is the line with accessor.Write(posheader, (byte) 10).

Is this correct or should we change it?

Sorry for the formatting, couldn't find the code button.

if (signal.OriginDataType.ToUpper() == "BYTE")

{

if (signal.GetType() == typeof(PLCInputInt) || signal.GetType() == typeof(PLCOutputInt))

{

if (lastbit)

posmemory = posmemory + 1;

bit = 0;

shm.bit = 0;

lastbit = false;

signal.Comment = $"M{posmemory}";

accessor.Write(posheader, (byte) 8);

shm.type = SIGNALTYPE.BYTE;

posmemory = posmemory + 1;

}

}

else if (signal.OriginDataType.ToUpper() == "WORD")

{

if (signal.GetType() == typeof(PLCInputInt) || signal.GetType() == typeof(PLCOutputInt))

{

if (lastbit)

posmemory = posmemory + 1;

bit = 0;

shm.bit = 0;

lastbit = false;

signal.Comment = $"M{posmemory}";

accessor.Write(posheader, (byte) 10);

shm.type = SIGNALTYPE.WORD;

posmemory = posmemory + 2;

}

}

else

{ if (signal.GetType() == typeof(PLCInputInt) || signal.GetType() == typeof(PLCOutputInt))

{

if (lastbit)

posmemory = posmemory + 1;

bit = 0;

shm.bit = 0;

lastbit = false;

signal.Comment = $"M{posmemory}";

accessor.Write(posheader, (byte) 10);

shm.type = SIGNALTYPE.INT;

posmemory = posmemory + 4;

}

}

Sorry if you saw my answer on the last message, but i thought it would be good to make a new topic! 

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 created a chain with chain elements and it is working fine. Now I tried to make a copy and turn it around 90°Z. Some of the chain elements are now moving in a wrong direction, but not reproduceable. Even if I create a new spline and replace all scripts, it is not working corrrectly. Shifting along the axes works, but turning is not possible.
Does someone know a trick?

Hello,

i have been working on a project that uses OPCUA to get some data from a server and when I execut it on the editor of Unity everything works fine but when I try to make the executable for windows platforms, in the executable doesn't connect to the server. Do I need to use any special settings to do the build on Windows?

Please if someone could help me with this I would really apreciate it. Thank you

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?

Building the project end with error. "ArgumentException: The Assembly ZeroFormatter is referenced by PREspective ('Assets/Plugins/PREspective/PREspective.dll'). But the dll is not allowed to be included or could not be found.

I Change Global functions "public static List GetGroups()" and "GetAllWithGroup(string group)" But, In corpasion it was witout differences.

I tried to build with differed API settings .NET 2.0 ant .NET 4.x

Probably there is probably problem with PREspective.dll, that doesn't properly connected to Unity, but I am not sure.

Do anybody has an idea ? thank you all.
