1 BACnet Gateway BACnet Gateway (5000BACnet) Connecting BACnet The BACnet Gateway is an embedded device that provides a field bridge between Clipsal lighting control systems and building management systems that support the BACnet open procol. The BACnet Gateway provides 255 group addresses from a single application address. About BACnet BACnet is a communication procol for Building Management Systems (BMS). This procol is managed by an independent organisation under the banner of the American Society of Heating, Refrigerating and Air-Conditioning Engineers, ASHRAE. The BACnet Gateway is a device known as a BACnet Building Controller or B-BC. The BACnet Building Controller contains software and firmware which perform the functions required allow group addresses be converted in BACnet objects and vice versa. When connected a BACnet system the BACnet Gateway can be scanned and its internal objects will aumatically be discovered by the BACnet system. These objects are used create the interaction between the BMS and the lighting control system. If more than one application address is necessary or more than 255 group addresses need be mapped, then additional gateway devices will be required. Each BACnet object contains properties which provide details of the group address. One of these properties is the analogue value, which in can be represented in different ways. As an analogue value from 0 255; Representing the level of the group. As a percentage from 0 100%; Representing the level of the group. The BACnet Gateway contains a preconfigured mapping table which provides the following connectivity. BACnet analogue value read objects; Allows BACnet read analogue values from. BACnet analogue value write objects; Allows BACnet write analogue values.

2 Connecting BACnet The BACnet Gateway exposes some of the properties of each group address BACnet as two separate BACnet objects; see below. In BACnet priority levels are used when two systems attempt control the same point. The BACnet Gateway expects commands using priority 16. For the Analogue write object the gateway performs processing after receiving the value from the Building Management System (BMS), but only if this is received as a priority 16 command. When the BMS system writes a value the Gateway this is passed on through the PC interface. will only transmit values over the network if the value is seen change. After sending the value on and receiving an acknowledgement of transmission, the gateway aumatically resets its internal value for the object a null value of 102. As the BMS must write a value of between 0 and 100, this is always seen as a change and therefore any transmission from the BMS, even a reassertion of a previous value will be transmitted on. The BACnet Gateway can be connected BACnet over Ethernet via BACnet I/P or using a serial connection via BACnet MSTP. Application Address Object Definition Group Address Dec.

4 BACnet Gateway Configuration BACnet Gateway Connections The BACnet gateway is supplied preconfigured from the facry. Some parameters need be supplied by the cusmer permit this configuration occur. Message transfer in a BACnet network relies on each device's connection a network having a unique address within the entire internetwork. This address is comprised of a pair of numbers. The first number is referred as the MAC (Medium Access Control) address, which must be unique on the local network segment which it is connected. The Medium Access Control setting is a BACnet address parameter and is not related an Ethernet MAC address. The second part of every device's address is the device instance number. This number is required be unique throughout the entire BACnet network.
