If it is a screen-sharing connection, it does not help. I already explained that I need to troubleshoot the client side on my own machine.

Hi,

The connection is via Azure Portal. Inside the browser. Not a VPN.

Thanks.

Please answer my question. Do you mean a VPN connection? That is the only possibility.

Hello,

what do you mean by "connect to the customer directly"? A VPN?

Hi,

1. It is possible to connect to the customer server directly. When can you connect? I will send you the connection instructions.

2. I tried using the EasyOPC Client ands also couldn't browse. See the attached screen capture. I also copied the exception error . See below.

Hello,

Thank you, but no, that's not going to work. I am talking about doing experiments with the server for many hours, and with the developer/debug version of QuickOPC which will need to be tweaked during the work. This cannot be done on your computers.

Best regards

Hi,

Yes. You can get access to the server via my computer. Please schedule a meeting using the calendar link below.

Hello.

If I get access to the server/trial (do you have download?), we can *try* to investigate and resolve it.
However, as I wrote before, I already know that the RSLinx browsing is broken, and there may be no solution, due to different approaches taken in our software.

Hi,

Now we can change the following settings programatically:
EnableNativeClient = True, EnableNetApiClient = False
or
EnableNativeClient = False, EnableNetApiClient = True

However, no matter which option we choose (NetApi-Client or Native-Client) when we try browsing the RSLINX OPC server for items we get an error and the items are not displayed. See the attached screen capture and the error message.
Note: In Matrikon OPC Explorer there is no problem.

Please advise.

Thank you.

Michael
