Issue
When discovering the SLP Series Living Space Sensors they show up in the BACnet discovery summary as Non-conformant.
Attempting to add this non-conformant sensor results in a WorkStation error similar to the following:
Validation Error

Error in "~/BACnet Interface/MSTP Network/Living Space Room Unit 4E5932F5_«1»_07/ForeignAddress". Property value "<device, 10000>" already assigned to "~/BACnet Interface/MSTP Network/SLPSTC2/ForeignAddress".

Cause
Building Operation does not allow duplicate BACnet IDs and hence, during discovery, if a device is found with a BACnet ID (Object Identifier) the same as an existing device it shows as a non-conforming BACNet device.
The default device ID for SLP devices should be equal to (Vendor ID * 1000) + MAC Address. Where vendor ID is our Schneider Electric BACnet vendor ID = 10 and the MAC address is unique to each devices MAC address DIP switch setting.
This will be corrected in a future release of the Living Space firmware.
Until corrected, and since the Device ID is a read/write attribute the customer is able to change it to avoid duplicates on the bus. Unfortunately, Building Operation does not currently have a method to write a new device ID.
Resolution
The current workaround is to use a third-party BACnet Explorer such as Yet Another BACnet Explorer (YABE) to write a new device ID value. Once the new ID has been updated the SLP device can then be rediscovered within Building Operations'.
