BACnet for Acuvim II Series Power Meter
1. BACnet Overview
The Building Automation and Control Network (BACnet), described in the ANSI/ASHRAE
Standard 135-1995, is one of the most widely used building management systems protocols.
BACnet was designed to allow communication of building automation and control systems for
applications such as heating, ventilating, and air-conditioning control, lighting control, access
control, and 󳆂re detection systems and their associated equipment. The BACnet protocol
provides mechanisms for computerized building automation devices to exchange information,
regardless of the particular building service they perform.
2. Introduction
The Acuvim II Series Power Meter supports BACnet communication using BACnet IP
communication and also BACnet MS/TP communication. It communicates in native BACnet
IP over Ethernet to seamlessly integrate with most building automation/control systems,
and communicates with the BACnet MS/TP via the RS485. The Acuvim II Series Power Meter's
BACnet MS/TP protocol supports has 56 prede󳆂ned BACnet objects that lets you track up to 56
measurements whiles the BACnet IP protocol supports 106 objects which lets you track up 78
measurements and 28 IO parameters.
The Acuvim II Series Power Meter supports native BACnet/IP that lets it act as a BACnet
server in any BACnet application. The Acuvim II Series Power Meter’s BACnet IP also comes
with a Web interface that allows users to con󳆂gure the BACnet related parameters and read
measurements by using a standard browser.
3. About BACnet Protocol
The BACnet protocol operates in a client-server environment. A client machine sends a service
request (message) to a server machine; once the service is performed the results are reported
back to the client machine. BACnet de󳆂nes 5 groups (or classes) of 35 message types. For
example, one class contains messages for retrieving and manipulating the object properties
described above. An example of a common service request in this class is "ReadProperty."
When the server machine receives this message from a client machine, it locates the requested
property of the requested object and sends the value to the client.

The BACnet protocol consists of Objects that contain di󳆁erent kinds of information. Each
Object has properties that contain data related to it.
Below is the example from the AXM-BMS(BACnet MSTP protocol) of an Object for Total Watts:
Object_Name, P_rms
Object_Type, AnalogValue
Object_Instance, 17
Present_Value, watt, tot (value in watts)
For more detailed information, visit the BACnet website at www.bacnet.org.
4. Using the Acuvim II Series Power Meter’s BACnet Protocol
Serial and Ethernet Versions
There are di󳆁erent serial and Ethernet based-versions of BACnet. The most common serial
version is called BACnet MS/TP while the dominant Ethernet version is BACnet/IP.
BACnet/IP has been developed to allow the BACnet protocol to use TCP/IP networks. You
could say that BACnet/IP is a way of hooking BACnet up to the Internet and communicating
with di󳆁erent Local Area Networks (LANs). This enables system owners, facility managers,
or even external suppliers to access BACnet networks and manage their devices and
systems remotely.

The BACnet module is linked to the Acuvim II meter by a communication plug. It can also be
linked to other extended modules like IO modules.
1. Insert the installation clips to the counterpart of the meter, and then press the BACnet
module lightly, so linking is established.
2. Tighten the installation screws.
Note:
• Install BACnet Module carefully to avoid damage;
• Under no circumstances should any installation be done with the meter powered on.
Failure to do so may result in injury or death.
5.2 De󳆂nition of RJ45 Interface and 485 Interface
The BACnet/IP module uses a standard RJ45 connector to access the network. The mechanical
and electrical characteristics of the connectors comply with the requirements of IEC 603-7.
