Connecting BACnet to XML

You have two devices in two different buildings on two completely different networks, one that uses the BACnet Ethernet protocol to communicate, while the other one talks XML protocol and they need to talk to each other. What do you do?

A FieldServer is a protocol converter or gateway that can communicate in many different protocols and physical layers including BACnet Ethernet protocol and the XML protocol. The Fieldserver acts as a middle man between the two devices. It reads data from one device, stores it internally and makes it available to the 2nd device using another protocol. This is how the FieldServer converts BACnet Ethernet data to XML data.

It's a simple solution to a common problem that we can help you with.

BACnet Ethernet

BACnet Ethernet is part of the ASHRAE’s BACnet family of protocols that operates on the Ethernet network. BACnet is mainly used for HVAC systems but recently has started showing up in all types of industrial automation, building automation networks and intelligent buildings.
With the help of a Fieldserver protocol converter we can set and retrieve BACnet Ethernet points, properties, and settings from your device and make them available to other networks and devices. The Fieldserver BACnet protocol driver can convert BACnet Ethernet to an impressive set of other building automation protocols by acting as a protocol converter or gateway. More information, Driver Data Sheet


We have general purpose XML drivers that use Serial, UDP and TCP/IP. They can all be client or servers. We also have a driver that extracts schedule data from an XML report. This driver makes the schedule date available as well as reporting the next schedule to use. Driver's time can be synched using any protocol.

We can also develop custom XML drivers for your.

XML defines a grammar as opposed to a language. Just because two devices have an XML interface doesn't mean they can simply exchange data. The way that the data is identified and packed inside the XML frame must be recognizable as must the formats of data requests.

Look in the FactSheets sections of our web site to find the data sheets for all the variations we support.
