As part of our series on BACnet best practices, we’re highlighting some of the most common diagnostic issues you’re likely to encounter.

This week, we’re focusing on a common BACnet issue, excessive read rate. Let’s look at what it is, why it’s not necessarily a bad thing, and how to identify misconfigured devices to keep your OT network traffic optimized.

What is KNX?

BACnet what is KNX protocol

BACnet gets compared to a lot of other protocols on the market, including LonWorks, Modbus, and KNX. Over the next few articles, we’re explaining how each of these protocols are different, and how they stack up against each other. In this article, learn about KNX.   KNX (short for Konnex) is not as well-known in […]

The Internet layer explained

Optigo Networks Intro to networking webinar with Distech Controls

The worlds of IT and Operational Technology (OT) are merging more and more these days as the Internet of Things grows in prominence. This collaboration between IT and OT is great, but there are still gaps in understanding that keep these worlds from fully working together. To help, we teamed up with Distech Controls to […]

What does a BACnet topology look like?

What defines a BACnet network? There are certain essentials you can expect to find on a basic BACnet network, according to KMC Controls: “A simple network requires only two or more controllers, an operator workstation and network wiring.” There are many physical topologies that can be used to design your BACnet/IP networks. The really important […]

What is BACnet Web Services?

What is BACnet web services, and what is its purpose?

BACnet Web Services is a standardized system that helps facilities managers integrate different types of information to understand their building and network. Traditionally, this would have to be done through a gateway that converts to a native protocol, such as BACnet. Now, you can do it all with one common service. BACnet Web Services was […]

What is a BACnet Broadcast Management Device (BBMD)?

What is a BBMD BACnet Broadcast Management Device

BACnet/IP predominantly communicates through broadcast messages, which are received by every device on the same network. Broadcasts are super important for discovering devices or finding and sharing new information. On big systems, though, you can’t have every device on every network sending and responding to broadcasts. If you broadcast to an entire system, it could […]
