About BACnet:
BACnet is an ASHRAE communication protocol for building automation and control networks.
(ASHRAE: American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc.).
VP3000’s BACnet is based on version 2004.
BACnet’s regulations are related to several kinds of physical layers’ interfaces. The physical layer built
inside VP3000 is achieved via MS/TP interface.
The BACnet of VP3000 supports a device type called B-ASC. B-ASC supports six types of services
such as DS-RP-B, DS-RPM-B, DS-WP-B, DM-DDB-B, DM-DOB-B and DM-DCC-B.
6-2-2 Wiring Configuration
⚫ Connection of the communication cable is as shown in the diagram below:
Pay extra attention that HW Pins of COM1_Port are shared by RJ45 and RS-485. That means
you can use RJ45_cable or RS-485_lines to access the COM1_Port.
When BACnet is enabled, COM1_Port will be dominated by BACnet function. Under this
condition, you will not be able to use Modbus VFD Soft, VFD Explorer or PLC function on
COM1_Port.
