Vendor devices, VND, do not have a configuration file. Sometimes you will find that the vendor provided a .PRN or .DDL file containing the point list. In other cases a Device Type Template needs to be generated for each Vendor Device from hard copy point list documentation.
The N2 protocol specification only reserved a single device code for Vendor devices. Therefore, the Configuration Wizard cannot determine the manufacturer, application, or any configuration details about the vendor device. All that we can tell by looking at the device from the N2 bus is that it is a Vendor device. It is a simple task to assign an appropriate Device Type Template to a VND device after the completion of the Configure Wizard.
Vendor, or VND, devices are 3rd party devices whose manufacturer has implemented the N2 Open protocol in the device. Typically, this was done through the Johnson Controls Metasys Compatibility Program.
As we encounter these at customer sites the resulting Device Type Template is added to our library.
