When the number of parameters managed by the OPCUA server is increased (from 30 to 120),

The values are being sent in bits and pieces.

Does the frequency of communication decrease in proportion to the number of parameters?

Hi, I’m using the OPCUA4Unity plugin purchased on the Unity Asset Store.I’m able to connect a Unity project to a OPCUA server with no certificates, but my main need is to connect it to a certificate based authentication OPCUA server. In the specific is a Basic 256 security policy.Trying to connect my Unity project to the certificate based authentication OPCUA server, filling the Security Policy field with Basic 256, I receive the following errors:

• OPCUA Interface - Connection Error Object reference not set to an instance of an object
• SocketException: A request to send or receive data was disallowed because the socket is not connected and(when sending on a datagram socket using a sendto call) no address was supplied.

Looking on the documentation I found that you specify that "Currently certificate based authentication and communication is not supported. We are working on the problem and try to find as soon as possible a solution.”
I would like to know if a new version of the plugin that supports the certificate based authentication OPCUA server is scheduled or if you have already a beta version or also a workaround for this issue.
Thank you

The OPCUA interface is used to obtain the data. At the beginning of the data update, the data change information can be obtained, but after a few minutes, the latest data cannot be obtained

On the OPCUA server, I logged in a user.

I set up the "OPCUA_Interface" component in Unity.

At that time, the "user name" and "password" set on the server were set to "OPCUA_Interface".

In this state, click the "Import nodes" button of "OPCUA_Interface".

Then the following error is displayed in the console.

「OPCUA Interface - Error in activating session [BadUnknownResponse]UnityEngine.Debug:LogError (object)」

Please tell me how to improve.

Hello,

I am trying to connect a CS9 controller from Stäubli, but the OPC UA server is published on the following address: 

opc.tcp://172.XXX.XXX.XXX:4880/Staubli

This last "/Staubli" data can not be written in the Port field or any other in OPC UA script, so the connection can not be stablished... It is not possible to modify the address in the controller, so I would like to know how can I define this address to properly connnect my server.

hi,

i am making a app watching Devices through the "KEPServer for OPC".

so, i made subscribe multiple nodes.

then i expected my app work similar with "OPC Watch".

the result i did test, some nodes was often get bad status.

If any of the nodes is in a bad status, your plugin only disconnects from a server without handling any after works.

Or, If some nodes is bad status at starting app and first connection, the App was get "Not Answer".

On the contrary, the OPC Watch is continue updating under the same circumstance stably.

Currently,

i make reconnecting when disconnected and trying to subscribe after checking that connection of a Bad nodes each seconds via ReadValue Method.

it seem to be not good way, i think...

what is the best strategy for handle a Bad status of node?

Hello

I am working on a project to work with realvirtual as HMI with OPCUA4Unity communicating with plc omron.

Reading and writing work perfectly while everything is connected.

The problem is that whenever the unity application connects the values used to write from unity to the plc are overwritten by 0 instead of being updated with the values from the plc in the first place.

Hello

I have managed to connect opcua4unity with the kepware server.

opcua4unity <-> kepserver <-> cp1l(omron) and opcwatch.

opcwatch connects perfectly with kepserver, reads and writes without problems.

opcua4unity connect ok, import nodes ok and read ok, but don't write values to server and plc.

attached photos.

I have also tried write value=on and subscribe value=off, but it doesn't work either.

Thank you.

Hi, I bought realvirtual,io for interface with Factory Robot to build Digital Twin

I followed realvirtual.io Youtube Guideline and build up Robot and Drive and successfully interface with our OPC-UA Server

but, there are some Graphical Issue in Robot.

the Drive Follow Position Module can get Tag Data, but some Robot motions skip in the Field.

How can I solve those Issue? Please Help.

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?
