TOPIC: Impossible to connect OPC-UA server

Hi,

I would be interested to use your TeslaSCADA software for Android to perform a demo with the OPC-UA server running natively on our simulator. We are using the software stack from Matrikon and we never have any issue to connect the OPC-UA server using different SCADA tools such as Zenon.

However, I cannot establish the communication using the TeslaSCADA application. I have an error saying: endpoint=null.

I am sure the network connection is fine since I am able to connect the OPC-UA server using the Prosys OPC-UA client running on the same tablet. Also, I can see the handshare using Wireshark. I have the wireshark capture file, if needed.

The settings I use to configure the server are the following:

URI: opc.tcp://192.168.0.190:4840
Mode: None
Policy: None
Anonymous mode activated (No username/password)

Any hint would be appreciated.

Hello,
OK. It will be helpful if you send us your project and wireshark file.

Hi,

Here is the file.

Many thanks.

Can you send us your project file also. You can do it by E-mail: Этот адрес электронной почты защищён от спам-ботов. У вас должен быть включен JavaScript для просмотра.

The problem has solved. OPC UA server send NULL in EndpointUrl information. We've made check this possibility in TeslaSCADA and use default URL if the NULL in Endpoint URL.
