If the Automation Server (AS) starts up with its clock set to 1970, it is possible to create duplicate object Id's.
EcoStruxure Building Operation
Automation Server, version 22.214.171.1248
If the clock in the AS is set before engineering the unit, the issue does not occur. However, if the clock is not set this problem occurs and the only was out is to re-engineer the AS. In addition, the BACnet interface will cease to function.
This issue has been identified as a defect, and will be resolved in a future release. In the meantime, be sure to configure the AS to the correct date and time prior to engineering the unit.
