Issue
MP/RP-x device is not pushing firmware down to Room Units (RU) when sensors are attached to the sensor bus.
Disconnecting and re-connecting the RU does not help
Product Line
EcoStruxure Building Operation
Environment
Building Operation Multi-purpose Controller
Cause
The MP-X controller's file system has been re-initialized and the Room Units firmware files deleted.
One case under which this will happen is when the MP/RP-X is factory reset.
The Device Report can be used to confirm whether the files exist in the device or not.
If Room Unit files are not shown in the report then no download to the RU will take place.
Resolution
Perform an upgrade on the MP/RP-X device, upgrading the device to the same version that is already running will resolve the issue.
