This is correct behavior.

In the OPC Servers, some items might be writable, and some not. The "Demo.Ramp" is not writable.

Use the "Browse items" button, and select an item that is writable - for example, Simulation -> Register_R4 .

Best regards

EasyOpcNetDemo ERROR : " The Items AccessRights do not allow the operation." was created by Nemcek
I tested a demo app but I encounter on this error after clicking on "Write item value".

The Items AccessRights do not allow the operation.
+ The client method called (or event/callback invoked) was 'WriteMultipleItemValues'.

Some tips for solution, please.
