Chipkin BACnet Command line (CAS BACnet Cli) interface is a command line application that sends BACnet client messages and parses BACnet response from BACnet devices as human readable text or as machine readable XML.
The CAS BACnet Cli application can be used for many purposes including;
- Create scriptable end to end integration testing for BACnet server applications.
- Extending existing application to discover, integrate, write devices, objects and properties of BACnet devices.
- Testing BACnet server applications.

Quick start
This is an example usage of the CAS BACnet Cli application testing against the CAS BACnet Stack server example
Get the version of the CAS BACnet Cli application and the CAS BACnet stack that the application was built on top
of
Command
CASBACnetCli.exe --versionOutput
CASBAC-2300-18 CASBACnetCli v0.0.2.0, CAS BACnet Stack v3.6.1.0Send a whois message to discover the local BACnet devices including the CAS BACnet stack server example
application.
Command
CASBACnetCli.exe whoisOutput

| 389 | 1476 | No |A whois.txt file is created in the base directory. This file contains the connection string, SNET, SDAR, and
device id. This file is used in other commands to look up the connection string, SNET, SDAR by the device id. This
file is especially useful when the device is on the other side of a BACnet router and has a SNET or SDAR.
The whois.txt file will look something like this
192.168.1.26:47808,0,,389999
192.168.1.203:47808,0,,389203
192.168.1.201:47808,0,,389201
192.168.1.202:47808,0,,389202
192.168.1.200:47808,0,,389200
Send a read property message with the property identifier of ALL (8) to a device (8) with an object identifier of
389999.
The property identifier of ALL (8) is special, and the CAS BACnet Cli application will send this request as a read
property multiple message instead of a read property message.
Command
CASBACnetCli.exe readproperty 8 389999 8 --deviceid=389999This command includes the --deviceid parameter. The deviceid parameter tells the system to search the whois.txt
file by the deviceid and extract the connection string, SNET, SDAR and use them for this command. The following
command is equivalent.
Command
CASBACnetCli.exe readproperty 8 389999 8 --ip=192.168.1.26 --port=47808 --snet=0Output

Received SimpleAck with originalInvokeId=[0] and serverAckChoice=[15]We want to send a read property multiple for several different objects and properties. We need to build the read
property message. The following commands do not send a message on to the network instead they save the parameters
to a local file buildreadproperty.txt
Command
CASBACnetCli.exe buildreadproperty 1 1 77
CASBACnetCli.exe buildreadproperty 1 1 85
CASBACnetCli.exe buildreadproperty 1 1 111
After the above commands have been executed the buildreadproperty.txt file will have the following contents.
