Issue
The message “Unsupported Unconfirmed service” is displayed in the Standard output Window of an UNC-520.
Environment
Niagara G3, R2, UNC-520, ENC-520
Cause
Some manufactures’ BACnet controllers use unconfirmed service which the UNC/ENC does not handle so they are ignored by the UNC/ENC.
Resolution
These are nuisance messages which cause no issues. The messages can be ignored.
