Metasys Integrators, MIG, was used by JCI to integrate devices with serial interfaces into Metasys. These configurations were all developed and provided by JCI. The MIG has its own unique configuration file. Sometimes you will find that JCI provided a .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 MIG devices. Therefore, the Configuration Wizard cannot determine the manufacturer, application, or any configuration details about the attached device. All that we can tell by looking at the device from the N2 bus is that it is a MIG. We get no indication of what type of equipment is attached to the MIG. It is a simple task to assign an appropriate Device Type Template to a MIG after the completion of the Configure Wizard.
As we encounter these at customer sites the resulting Device Type Template is added to our library.
