CAS BACnet Explorer is the perfect utility for Discovering, Exploring, Monitoring, Debugging, Testing, and Creating reports of your BACnet® networks and devices. It performs the following functions:

  • Exploring – Automatically discovers all the BACnet devices, objects, and their properties on your network. The objects and devices are arranged in an easy-to-use tree format.
  • Debugging – With the report function, you can document the current state of your BACnet® network. Never again ask yourself if a BACnet® device is on your network, and what value it has.
  • Monitoring – A monitoring table can be set up to check the present value or any other property of a BACnet® object, easily with a single glance.
  • Testing – The CAS BACnet Explorer allows you to write to the BACnet® points, turn lights on or off, generate alarms, ACK alarms, etc.

The CAS BACnet Explorer supports the following features:

The discovery feature is used to find and explore BACnet devices. The BACnet Explorer can send a simple BACnet Who-Is message to it and can perform a full network discovery of all BACnet devices, objects,  and properties. This allows for a new level of flexibility when working with your BACnet Networks.

Once discovered, the BACnet devices and objects are displayed in a cascading network tree by BACnet network, device, and objects for simple organization and searching.


The CAS BACnet Explorer allows you to write to the BACnet points, turn lights on or off, generate alarms, ACK alarms, etc.

Custom rendering of properties

The properties of an object are rendered depending on its data type and property identifier. This allows custom rendering of properties in a more familiar way than raw values.

For Example

  • The Enumerated (9) can be displayed as both the enumerated text and the enumerated value.
  • The Octet String (6) can be rendered as 2 character hex values separated in an array of boxes.
  • The BitString (8) for Status Flags (111) can be rendered with the text for each status flag.
  • The Boolean (1) can be rendered as a true or false
  • Etc.

Auto-refresh and data age

The property list can be automatically refreshed by toggling the “auto-refresh” switch above the property list.

The CAS BACnet Explorer will attempt to rediscover the selected objects’ properties every 3 seconds and refresh the display.

This feature can be useful for monitoring the present value of an object as it changes over time.

Export / Import database

After discovering the devices and objects, the database can be exported to a database file (JSON).

This database file can be imported and viewed offline. This file can also be used as documentation or used to configure BACnet clients.

Being able to export or import files facilitates remote work and collaboration.

Network Adapter selection

Modern computers have multiple network adapters. For example an Ethernet adapter and a Wifi adapter.

The CAS BACnet Explorer allows the selection of the network adapter to ensure that the traffic is sent out on the correct network.

BACnet for Field Technicians

Chipkin originally released the CAS BACnet Explorer v2.00aA in 2002 as a simple tool for discovering BACnet devices and objects on a network and validating the present values. It has been updated many times since its initial release with new features requested by our customers. CAS BACnet Explorer was last updated in 2012 with version v2.02aW as it satisfied most of our customers' needs.

A lot has changed in BACnet spec since 2012. COV, BBMD, Network port objects, Elevator objects. One of the most exciting changes has been the introduction of BACnet SC (Secure Connect) in ANNEX AB. BACnet SC uses web sockets to add TLS encryption and security, in a hub and spoke configuration.

Chipkin updated the CAS BACnet Stack to support BACnet SC data link protocol. This allows companies to embed the CAS BACnet Stack into their product and expose their data with a BACnet interface. The CAS BACnet Stack supports BACnet IP, BACnet MSTP, BACnet Ethernet, and BACnet SC data link protocols.

With the addition of BACnet SC, Chipkin needed a tool to help their customers discover and validate BACnet SC devices. We also wanted to improve the adoption of BACnet SC in the industry. Thus we decided to update the CAS BACnet Explorer.

Thank you once again for your help testing the latest version of the CAS BACnet Explorer.
