ALL THINGS BACNET
The PS24 Serial version supports writable max_master and max_info_frames properties in the device
object for MS/TP networks. For best network performance, the max_master should be set to the
highest MS/TP MAC address on the network.
The max_info_frames does not need to be changed in most installations.
The device ID property of the BACnet device object is also writable. All device IDs on a BACnet network
must be unique.
The PS24 Ethernet version can register as Foreign Devices to a BBMD.
BBMD
stand for
BACnet/IP
Broadcast Management Device
. The address also can be written to BACnet object identifiers 14014
(BBMD IP Address LSW) and 14015 (BBMD IP Address MSW).
NOTE:
The LSW/MSW are in network order.
For example to set the BBMD server to 192.168.1.100 you would write:
43200 (0xA8C0) to BBMD IP address LSW object identifier 14014
-and-
25601 to (0x6401) to BBMD IP address MSW object Identifier 14015
This sends the register as foreign device packet with a Time to Live (TTL) of 60000 seconds.
To disable BBMD foreign device registration write 0 to both BBMD IP address LSW (14014) and BBMD IP
address MSW (14015) or simply write 0.0.0.0 to the BBMD field in the ViewPoint Comms Setup tab.
