How do I prevent errors when accessing DDL menu items in NI Configurator?

[mrbob]

I am developing a DD description for a Foundation Fieldbus device. I have put menus in the DD to help present the data in my transducer blocks in an organized manner. When I access a menu item with NI Configurator 3.0, I get an error message "Network read of parameter name failed: error code -27" (See attachment). This happens for all the variables on my menus. The same variables are read correctly within the block views.

Are there any specific requirements of menus, or unsupported DDL constructs that can not be used within DDL menu items when using NI Configurator? I have tried the Menus on other fieldbus host systems and they appear to work OK there.

Are you calling "Edit Display" in your DD menu? As I know, the Configurator 3.1 version can handle "Edit Display" properly. I suggest you send your DD and CFF files to "fieldbus.support@ni.com" for further technical support from NI.

On the other hand, you might be able to download the Configurator 3.1 Evaluation version from "http://www.ni.com/support/fbussupp", which supports creating virtual devices/blocks with CFF and DD files. You can try on that and see whether it helps in 3.1 version.

No, I am not using edit_display. Just plain variable names on a menu. I will try sending the DD as you suggested. Thanks.
