BACnet OPC Server - KEPServerEX OPC Servers

Overview

The BACnet Device Driver was designed to plug into our industrial based communications server product and is intended for use with Building Automation and Control Networks. This product supplies data access to any HMI, SCADA, Historian, or Enterprise application that supports OPC, DDE, Advanced DDE, FastDDE, or SuiteLink. It provides connectivity to equipment using the BACnet protocol over Ethernet (often referred to as ("BACnet/IP" or "Annex J"). Devices on other BACnet network types may be accessed using BACnet gateway devices.

BACnet Resources:
The official BACnet specification, "ANSI/ASHRAE Standard 135-2001 BACnet A Data Communication Protocol for Building Automation and Control Networks", describes all aspects of the BACnet protocol. It is recommended that users of this driver be familiar with the standard BACnet objects and properties discussed in Clause 12 of the specification. In addition, you should be familiar with the particulars of BACnet/IP outlined in Annex J of the specification. The specification document, as well as many other useful resources, is available through the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) or the official BACnet web site www.bacnet.org.

Devices

Supported Devices

Note

This driver can be used successfully with devices that use the BACnet/IP (Annex J) protocol, are visible on or from an Ethernet network, and support the objects, properties, and services supported by this driver. You should consult the Protocol Implementation Conformance Statement (PICS), available from your hardware vendor. Conformance data for this driver is given in Supported Objects and Services found under the features tab.
