Babel Buster BB3-7101 BACnet IP to Modbus Gateway provides a BACnet IP client and server, Modbus TCP client and server, and Modbus RTU port configurable to be master or slave. Most often used to connect Modbus devices to a BACnet IP network, the BB3-7101 is configured via simple web page templates to read and write Modbus registers in one or more Modbus slaves, making that data accessible as BACnet objects on the BACnet IP network.
The BB3-7101 includes a BACnet IP client which allows BACnet IP devices to be accessible from Modbus TCP or RTU. You configure the device instance, object type and instance, and poll interval for reading or writing BACnet objects. The object data is stored in the BB3-7101 server for subsequent retrieval by the remote Modbus client (or master). The same polling schemes that apply to Modbus also apply to remote BACnet IP slaves polled by the BB3-7101's BACnet IP client.
The BB3-7101-SP is a special version of the BB3-7101 that allows one to repurpose the serial communication port to be used for a proprietary serial protocol instead of Modbus RTU. When used for interpreting a proprietary protocol, a Script Basic program would be written to send and receive via the serial port as applicable, and interact with the local BACnet objects under user program control.
The BB3-7101-SP allows you to BACnet enable enable serial devices that otherwise have no network connection. Combined with rule templates, Script Basic can generate BACnet COV notifications. Script Basic also has access to TCP and UDP connections, and can potentially interpret proprietary IP protocols as well.
