BACnet Packet Capture and Protocol Analyzer for MS/TP

If you're a developer trying to build BACnet MS/TP devices, chances are you're struggling to make your MS/TP implementation work properly and inter-operate across vendors. Looking at the BACnet standard, you know that even simple MS/TP communications can present some daunting problems, and you probably don't have the time to become that much of a BACnet MS/TP expert. With so many things going on simultaneously on a typical MS/TP network, you need easy and reliable tools to help you get right to the heart of subtle MS/TP problems. You need something designed specifically for MS/TP debugging, and pricing that won't blow your budget. You need BACtrace™.


The multi-pane user interface shows captured packets in several different kinds of detail. The upper pane displays a quick summary of received packets, each of which is identified by number. The MS/TP frame type, destination and source MAC addresses are shown, as well as a timestamp in milliseconds. For APDUs, the BACnet service is also shown.

The lower panes display detail information for selected packets. On the left is a hexadecimal display of raw packet information. The hexadecimal values are arranged on the same line with the interpreted protocol analysis shown in the right hand window. The right hand window displays a detailed analysis of the NPDU and APDU. The protocol analyzer engine uses fifth generation technology which supports the complete ANSI/ASHRAE 135-2012 standard. The left and right hand panes are synchronized when scrolled so that you can easily see the component encoding of portions of each packet. You can select portions of any of the panes for individual printout, saving to a file as text or copying to the clipboard. You can even export the capture in the popular WireShark format.


BACtrace outperforms WireShark captures with superior timing accuracy and ease-of-use.


BACtrace is a must-have tool for any MS/TP developer and is extremely useful for finding MS/TP-related problems in the field.
