New Features in Visual BACnet
June was an extraordinary month, with 20 power users on Visual BACnet 

June was an extraordinary month with 20 power users on Visual BACnet providing us with regular feedback. Our development team was kept busy adding features and making changes to the product. Over the last six weeks we have launched many new features and made pre-existing features more user-friendly. Take a look below for a few of the biggest additions.

1. Network health is now explained.


The updated network health score is clickable. Now you can see exactly how the score is calculated, and understand how you can improve it.

To calculate the network health, each diagnostic check is classified as either a “scored check” or a “critical check.” The scored checks are graded out of 5, 10, 20, or 50 depending on their importance, and these make up the base percentage score. Examples of scored checks include:

  • Unanswered who-is
  • Unconfirmed-COV traffic
  • Long response times
  • Error PDUs

High volumes of any of these result in a lower network health score.

The critical checks are those diagnostic checks that reflect a huge problem in the network. If one of the critical checks fails, it automatically deducts 10%, 20%, or 30% from the final score to reflect the severity of the failure. Examples of critical checks are:

  • Circular networks
  • Duplicate device IDs
  • BACnet buffer full broadcasts

The scored checks, minus any critical checks, make up the final network health.

2. Missing ACKs and Error PDUs now accessible.

Through our new statistics summary section you can access the missing ACKs and the error PDUs with their corresponding confirmed REQ.

When a device sends a “confirm request” to another device or the BMS and does not receive an acknowledgment, it will show up under “missing ACKs.” You can then drill down into these by service choice, into the specific packets where the missing ACKs exist. Error PDUs can also be accessed with their matching “confirm request.”

3. Packet browser allows you to drill into your pcap file.



Isolate just the packets you need based on your own requirements using our packet browser. Save time filtering in Wireshark and Excel by using our packet browser.

Choose to drill down into your packets by source, destination, PDU type, or network. From there, you can sort and select different options until you find the packet of interest.

4. Get immediate answers by chatting with our team.

When Tom Walker looked at Penn State University’s Navy Yard network, he saw big issues. 

The system was busy and loud. So loud, that the overrun MS/TP network was bringing down the entire building. 

We know, at the end of the day, the decisions you make for your business or building come down to time, money, and effort saved. What’s going to prove the most reliable, secure, and overall simple to use?

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 residential 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.



When Delta Building Automation (Australia) won the BMS Upgrade at 25 National Circuit for the Australian Trucking Association, they partnered with Optigo Networks to create a secure and robust Building Services Network (BSN). Optigo Connect more than delivered on this project with a scalable solution that restored the building network to perfection.

Optigo Connect Seattle Stadium


Optigo Connect offered a simple, cost-efficient solution for a premier Seattle-based stadium. Optigo Networks’ design improved the surveillance system to crystal clear perfection, made it dependable, and allowed the security system to scale with the addition of more than 40 16MP cameras.



Optigo Networks and OTI offered a secure and scalable solution for four data centers’ HVAC and Access Control systems throughout the United States. Optigo Connect’s performance in the first data center was so impressive, the client asked that Optigo replicate the network design for three other data centers.
