Issue
A site has a UNC-520 with ibsMs Service and approximately 20 MicroSmart controllers. A serial tunnel is successfully established to the UNC. From the Operator Interface main page, MicroSmart is accessed. After a few seconds, an error appears indicating that there are no controllers under the currently selected DCM.
A DCM is a board that works with a DMS350A. However, the site has no DMS installed, just a UNC and MicroSmart controllers.
Environment
Niagara R2
DMS
MicroSmart controllers
Cause
Polling is not enabled in the UNC's MicroSmart Service.
Resolution
Re-enable polling and reboot the UNC.
