Server Offline. Duplicate device name or network identifier alarms received

Server Offline. Duplicate device name or network identifier alarms received

Issue

Automation Servers go OFFLINE

Alarms received about duplicate device name and/or duplicate network identifier.

Product Line

EcoStruxure Building Operation

Environment

  • Enterprise Server, ES
  • Automation Server, AS, AS-P, AS-B
  • BACnet

Cause

In the BACnet interface duplicate information has been entered for the BACnet IP network for 2 or more Automation Servers.

Resolution

Make sure the BACnet IP network and broadcast address in the BACnet interface of the ES and all the Automation Servers  are set to a unique value and they match the IP address of the Server (AS, ES)

You may have to physically disconnect the units from the network and then connect one at a time in order for Workstation to be able to communicate with the AS and change the configuration of the BACnet IP network.
