Environment

Enterprise Server

ES

Automation Server

AS

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.

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.
