Common BACnet IP and Ethernet issues

Common BACnet IP and Ethernet issues
Solving common BACnet IP problems like Unresponsive Devices and Global Who-Is

There are many different issues that can crop up on IP and Ethernet networks. 

While MS/TP problems tend to be centred around bad wiring, IP and Ethernet are usually the result of a misconfiguration. A study of two years’ worth of data showed that some of the most common IP and Ethernet issues include Unresponsive Devices (71% of files), Unresponsive Routers (24% of files), and excessive Global Who-Is Router Broadcasts (19% of files). These are the most common problems we see on BACnet IP networks, but the list goes on.

Many of these network issues could be related. For example, excessive broadcasts might cause devices to be overwhelmed, shut down, and become unresponsive. This would flag at least two diagnostic checks in Visual BACnet. If you can uncover the root issue, you might solve several problems in one go. 

1. Identify the problem

Visual BACnet finds and highlights a wide variety of issues, like Global Who-Is, Duplicate Device IDs, Circular Networks, Duplicate BBMDs, Duplicate Networks.

2. Pinpoint the device(s)

When you dig into the data and click on a failed check, you’ll see which devices are causing issues. You’ll see the vendor name, Device ID, IP address, and more when you hover over an entry in any of the checks.

3. Resolve the problem(s) 

Any failures or warnings in the Critical Checks should be addressed first. Start at the top and work your way down! You’ll likely solve a lot of smaller problems by solving the big ones higher up on your list. 

Monitor your networks, with the Visual BACnet Capture Tools for IP. Install these devices on your network and they’ll passively monitor, capture data, and send the information up to Visual BACnet for analysis. When issues arise, you’ll get an alert so you can dig in, identify problems, and quickly solve them. Learn more.

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.

Data center expansion with OTI and Optigo Connect

DATA CENTER EXPANSION

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.

45 BENJAMIN WAY

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

PENN STATE UNIVERSITY

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

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.
