Dear Sir,

I am implementing a server using TUaServer and using Prosys OPC UA Browser 4.4.0-126 for testing.

When calling a method without OutputArguments during method implementation, the ‘Call Method failed’ message is displayed.

Regardless of the number of InputArguments items (including no items), if there is at least 1 OutputArguments, it is processed normally.

The method is processed using NodeManager.MethodManager.AddCallMethod( CallHandle ), but I would like to ask whether OutputArgument must be set to at least 1 in the method configuration.

Thanks for your support.

Best regards,

Jang.
