Your code is incorrect for what you want to achieve.

Modify it according to the following, i.e. specify reading from the device, as I have told you earlier :

- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...ems%20from%20the%20device.html

- opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...m%20OPC%20Classic%20Items.html

Hello.

I am not sure from your answers that you are doing the recommended way.

Please post here the piece of your code that prepares arguments for ReadMultipleItems, and calls the method.

You are not answering my question. It has nothing to do with subscription.

Have you changed your program to use read from device, as I described in one of the previous posts?

Currently, it is a polling, not a subscription.

Use the ReadMultipleItems function to make a request to the server and receive data.
