New Features for Visual BACnet
Visual BACnet version 1.6 has a plethora of long-anticipated features

MSTP Diagnostic Checks


Three brand new diagnostic checks have been introduced.

  1. Average Token Round-Trip Time (RTT) is an average of every token round-trip that happened during a capture. A high token RTT often indicates a high amount of traffic and/or can also point to potential buffer overflow.
  2. Standard Deviation of Token Round-Trip Time shows you if the time it takes a token to complete a round trip varies dramatically throughout a capture. This would indicate something is interrupting token trips.
  3. Token Disruptions happen when a token is lost. The device sends a token retry, and if this is unsuccessful it sends a Poll for Master. This indicates that something is very wrong in the MS/TP network.



On the bottom of the summary screen you now have the ability to add comments. These comments will stay in the file, and can be used to makes notes and observations. By ticking the box in the bottom right saying “show on report” you can choose for each comment to appear on the downloadable PDF report.

Add a non-standard BACnet Port



In the top right corner of the summary screen you can access your settings. In settings you can add a custom BACnet port. This will allow packets from this custom BACnet port to be analyzed in addition to the standard BACnet ports that are automatically analyzed. The custom BACnet port needs to be set prior to uploading the PCAP file. Once the PCAP file is uploaded and analyzed, the custom port can be changed without impacting the stored information.

Enable and Disable Diagnostic Checks


By clicking on the wrench icon by Diagnostic Checks on the summary screen, you can access your Diagnostic Check Settings.


In these settings you can disable specific checks, and add comments as to why you disabled them. These comments will appear on the PDF download report. Be sure to “save changes” after adding comments. Note that the thresholds are shown but cannot be modified. We believe these thresholds need to be universal for the Health Score to be relevant.

Devices Observed


The summary of devices that have been active during the capture has been split into fully identified devices and partially identified devices. Fully identified devices have an I-Am in the capture that allows us to identify them. Partially identified devices do not have an I-Am in the capture. They do, however, have either a Who-Is that is allowing us to identify them, or an SNET and SADR that allows us to partially identify them.

Enjoy these new features, and please don’t hesitate to provide your feedback. Maybe it’ll make it into v1.7!

An excess of Global Who-Is/I-Am messages can be devastating on BACnet networks. Particularly on a big network with lots of devices, it’s important to limit broadcasts to only the necessities. 

The BACnet Browser in Visual BACnet allows you to customize the information you see and isolate the specific packets you need to solve your problem.

The router and gateway play key roles in your BACnet network, and are often easily mixed up. It’s important to understand how these disparate parts communicate with one another.

Recent Projects

Data center expansion with OTI and Optigo Connect


Stack Infrastructure is a portfolio of hyperscale computing data centers. OTI completed work on Phases I and II, and returned for the Phase III build-out of a 4-megawatt data hall and brand new central plant. The Optigo Connect network put in place in Phases I and II was expanded on this project. The team achieved quick roll-out of a large, multi-service redundant network using the Optigo OneView management interface. Going forward, the facility management team can use OneView to remotely monitor equipment, manage power usage, and meet up-time goals.

Optigo Connect MR Soluciones The Landmark


The Landmark is a sophisticated mixed-use high-rise in Mexico. The owners wanted to integrate all OT systems in the skyscraper, while maintaining separate networks for each application. The Landmark is the fourth joint project between Optigo Networks and MR Soluciones. Together, these companies provide robust services to meet any challenge.

Australian Bureau of Statistics at 45 Benjamin Way with Delta Building Automation


Delta Building Automation (Australia) had a big job renovating the Headquarters for the Australian Bureau of Statistics (ABS) at 45 Benjamin Way. The building owner wanted to improve the building’s energy use and increase their National Australian Built Environment Rating System (NABERS) score to more than 4.5 stars, out of a possible total of six. Securing the network both internally and externally was a big priority, as well.

Penn State University Optigo Networks Visual BACnet


When Tom Walker looked at Penn State University’s Navy Yard network, he saw huge issues. The system was busy and loud, to the point where the overrun network was bringing down the entire building. Because this was happening on the MS/TP network, pinpointing the problem would mean boots on the ground to segment and test the chain, piece by piece.

Penn State University Optigo Networks Visual BACnet


When Tom Walker first started working at Penn State University four years ago, there were a lot of network issues. Buildings were dropping offline. Broadcast traffic was pushing 90,000 packets per hour. Walker was on the phone almost every single night because devices were down or had to be reset.


Torre Manacar Mexico City Optigo Connect


When MR Soluciones began work on Torre Manacar, they knew they needed a flexible and scalable network infrastructure to support a wide array of integrated systems. Optigo Networks was a natural fit for the massive project, designing a robust network at a competitive cost.



Short Pump Town Center, an upscale retail center, underwent a complete renovation in 2014. The flexibility of Optigo Networks’ solution meant the retail center’s unknown final design was not a barrier to placing IP surveillance equipment in the field.



Optigo Networks connected New York-based Boulevard Mall’s security surveillance devices in December 2015, using a Passive Daisy Chain topology.

Visual BACnet tech support team


One tech support team at a manufacturer purchased an account with Visual BACnet in April 2017, for technical problems around the world.

Aster Conservatory Green Optigo Connect


The Aster Conservatory Green is a community comprising 352 residences across 24 low-rise buildings. The buildings use advanced surveillance and access control technology, including 40 HD video cameras and 60 FOB-access-tele-entry points for access control.
