Functions
The selected application and its parameters as well as input and output configuration
determine the automation station’s functionality.
A detailed description of functionality is available in the ABT (Automation Building Tool)
online help.
Communication
● 2-port Ethernet switch for cost-effective cabling via line topology.
Note: DXR1 supports cabling based on daisy chain topology. The max. number is 20
devices and in the event of a failed automation station, all other stations are no longer
reachable. DXR1 can be cabled as ring topology if higher reliability is required. This
requires support for layer 2 switches RSTP (Rapid Spanning Tree Protocol) as well as
SNMP monitoring and that any loss of superposed system is reported. In the event of a
fault, switching the communication paths can take between 10 and 30 seconds. DXR1
routes the RSTP protocol for the switches. It does not actually process the RSTP
protocol. Further information can be found in Application Guide for BACnet Networks in
Building Automation (A6V11159798).
● USB connection for service, commissioning and firmware download.
