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.

Hi, sorry for the late response.

Thanks for the note. It seems this problem has been fixed in the development version of UaBrowser, which is not released yet.

You can send email to uabrowser-support at prosysopc dot com to ask for the latest beta version that fixes this issue.
