There are a dozen or so demo applications that are built
with the default makefiles. These demo applications are
copied to the bin/ directory. They can be used in
scripts and batch files to test BACnet devices or query
information on the BACnet network, as well as simulate
a BACnet device.
The demo applications make use of Environment Variables
to configure the network.
BACNET_IFACE - interface to use for the datalink layer
For Linux, this is something like eth0 or /dev/ttyS0.
For Windows, this is something like 192.168.0.1 or COM4
Defaults to NULL.
BACNET_IP_PORT - BACnet/IP port number.
Defaults to 47808.
BACNET_BBMD_PORT - BACnet/IP BBMD port number.
Defaults to 47808.
BACNET_BBMD_TIMETOLIVE - BACnet/IP BBMD time-to-live seconds.
Defaults to 0xFFFF.
BACNET_BBMD_ADDRESS - dotted IP address or domain name of BBMD.
Attempts to register with the BBMD if this variable is present.
BACNET_MAX_INFO_FRAMES - BACnet MS/TP max-info-frames parameter.
Defaults to 127.
BACNET_MSTP_BAUD - BACnet MS/TP baud rate.
Defaults to 38400.
BACNET_MSTP_MAC - BACnet MS/TP MAC address.
Defaults to 127.
The demo client applications can also perform static
address binding using the file "address_cache" in the
directory where the application is called (defined
in src/address.c file). The format of the address_cache
is a line by line of device ids and addresses:
55555 AC:10:56:06:BA:C0 26001 19 50
where:
55555=device id in decimal
AC:10:56:06:BA:C0=MAC address (router address) in hex
26001=DNET network number in decimal
19=DADR MAC address in hex. Use colon to separate multibyte address.
50=Max APDU
