BB2-7030 Base Model with Modbus Support

The BB2-7030 as a BACnet Slave Proxy will provide I-Am responses on behalf of devices that do not have I-Am support, or are slave-only devices. The slave proxy capability will allow systems to utilize dynamic address binding with devices that do not support dynamic binding.

The BB2-7030 as a BACnet Client/Server Gateway will poll BACnet IP and/or BACnet MS/TP slaves or servers, and retain copies of selected object Present Value properties. Upstream masters may then query the BB2-7030 to receive Present Value data originating from multiple devices. When used as a gateway, the BB2-7030's routing can be disabled to avoid conflict with other routers on the network.

The base model BB2-7030-01 includes a Modbus TCP client/server that provides optional BACnet to Modbus gateway capability. Value objects will poll their assigned Modbus register at the interval you specify. The content of the Modbus register will be given as the Present Value of the BACnet object when read. The Modbus register is written each time the BACnet Value object is written. The Value object corresponds well with the Modbus Holding register.

As a Modbus gateway, Input objects will poll their assigned Modbus register at the interval you specify, and provide the Modbus data as the Present Value when read. Commandable Output objects are used to write Modbus registers, and will update the Modbus device each time BACnet is updated.

Models BB2-3060 and BB2-7030 can both be used as an MS/TP to Modbus TCP gateway. Which one should you use?

If you are familiar with the BB2-3010 Modbus RTU to BACnet MS/TP gateway, and would like to use a Modbus TCP version of the same gateway using the same configuration tool, then the BB2-3060 is the better choice. Some will find the Windows based configuration tool for the BB2-3060 to be more convenient than the web based configuration of the BB2-7030.

If you are already familiar with the BB2-7010 or BB2-7030, then the BB2-7030 will have a familiar look and feel. However, because the BB2-7030 is also a BACnet router, it will potentially cause problems if you do not disable routing when there are other routers on the network and you only want to use the BB2-7030 as a gateway. If you prefer web based configuration, then the BB2-7030 is a good choice for you.

BB2-7030 with SNMP Support

The BB2-7030-02 provides an SNMP client and server instead of Modbus TCP. The combination of SNMP agent (server) and BACnet client makes BACnet devices accessible from SNMP. The SNMP client allows SNMP devices to be accessible from BACnet. You configure the remote SNMP agent's IP address, the OID of the MIB variable you wish to poll, and set a polling interval. The object data is stored in the BB2-7030 server for subsequent retrieval by another BACnet client.

The BB2-7030 includes its own internal web server that provides a web based user interface for configuring the BB2-7030. Configuration is done using simple templates, and each web page has an online help section at the bottom.
