Introduction

BACnet is a Data Communication Protocol for Building Automation and Control Networks. It is a standard protocol developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). For more information see http://www.bacnet.org/.

BACnet is recognized by:

The BACnet Driver in Fernhill SCADA supports devices using the BACnet protocol.

Fernhill SCADA BACnet Tags

The BACnet Driver provides these tag types to support communication with BACnet Devices:

IconTag TypeVersionDescription
Channel Icon BACnet/IP Channel Tag 3.78 An IP Address used for BACnet/IP communication.
Device Tag BACnet Device Tag 3.78 An BACnet Device.

To configure Fernhill SCADA to communicate with a BACnet Device do the following:

  1. Create and configure a BACnet/IP Channel Tag.
  2. Create a BACnet Device Tag. Configure these properties of the BACnet Device Tag:
  3. Create I/O Data Point Tags to represent the data in the BACnet Device. For each I/O Data Point Tag you create:

Fernhill SCADA I/O Data Point Tags

You can use these I/O Data Point Tags to represent individual data points in the PLC:

IconTag TypeVersionDescription
