Which version of robodk is compatible with game4automation opc ua or game4automation professional. I ask, because I want to communicate robodk 4.0 with game4automation professional.
I was wondering when will OPC UA for Unity 2019 will be supported?
With kind regards,
Stan (Developer at Siemens)
Hi, we have no tutorial about that.Even if Unity 2019 is not officially supported yet, you should be able to get it running. What is your problem. What kind of error messages do you have?
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!
For the moment I don't know how to proceed here. If you write an object I don't know the reason why the type is being changed. What you are doing is more than the standard features and functions we provide. It would need some work on our side to check where the problem is. Maybe you did a mistake in how you pass the Extension object. But really hard to say without having the same setup. If you could somehow give us a full setup (OPCUA test Server with needed data structure and a reduced part of your code where we can check what is happening) we can check it. But this is so special that we would need some support budget if the effort on our side is to high.
How to subscribe multiple nodes and with events? Fyi i need to subscribe more than 200 nodes to monitor (is this possible using the client?). Based on the documentation it only explain subscribe for one node and event.
The OPCUANodeSubscription object includes everything you need, e.g. the NodeID of the node which changed.
Hi I am using DEMOOPCUA on unity 2020.1.13f1. I am working directly on the demo templates. After switching to a different opc ua server, information are not automatically updated, this is unlike in the original demo template where data are automatically updated. Is it something that i am missing?
I'm trying to connect via OPC UA to a Node-RED OPC UA server. This server allows me to create nodes on root level.
If I do not specify a Top Node Id I get the following error:
Is there a way to connect to nodes I've created as shown above?
Hello, i work as a developper for a small company. We recently started working with your tool Game4Automation in Unity for industrial projects, and especially with the OPCUA4Unity technology. I understood that this specific part in Game4Automation has been developped following Trager Technologies.
As a company we have one Unity account on which we are actually creating two projects, our problem right now is that my coworker often get LicenceException about the use of OPCUA, which i don't. I was then wondering on what type of licence the Opc.uafx library was incorporated inside Game4Automation, do we need to purchase two licence of Game4Automation to avoid any licence troubles and the 30 minutes free trial of Opc ua technology?
I hope you will get this message, i can precise anything if needed.
Have a great day!
if you are working in parallel, you need to have 2 Game4Automation licenses. Game4Automation is a Editor Extension that means that you need to have one license per seat.
There seem to be sometimes a problem with the included OPCUA license. We can't see the same problem on our computers, but I had one other customer with the same problem. The reason is the included OPCUA dll and it's licensing mechanism. We are working on an update of the included OPCUA dlls and this will solve most probably the problem.
Hello, I'm currently working on a project that requires reading of thousands of node values. Currently your documentation implies we should subscribe to nodes using OPCInterface.Subscribe() however, this makes a new subscription for each value which quickly reaches a limit. Is there a procedure for adding new monitored items to a single subscription?
Ho Jacob, we have now a beta whoch is able to have the needed limits. It is currently tested by a few customers and will be released soon.
If you are interest I can send you the beta.
is it possible to run the OPCUA Interface inside a webgl app? I tried with Unity 2018.4.15 and 2019.2.17 and always got a "Memory index out of range" error in Chrome and Edge.
No WebGL is not supported - sorry. I also think that communicating in a Web application over OPCUA might also be not wished from the security point of view.
since the last update I get an LicenseException when building for Android. I only get the error on the device not in the editor.
"LicenseException: The supplied license is not longer supported for this version. You need to renew your support subscription to use this version of the OPC UA Framework Advanced."
I use the OPCUA4Unity asset from the asset store. Since I get this error on already shipped devices I realy need a quick solution. Thank you!
I am closing this. We can't reproduce it.
