You configure the device instance, object type and instance, and poll interval for reading or writing BACnet objects. The SPX-B includes a BACnet IP client which allows BACnet IP devices to be accessible from Modbus TCP or RTU. Most often used to connect Modbus devices to a BACnet IP network, the SPX-B 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.
Optional SNMP client and server, includes trap send on thresholdīabel Buster SPX-B 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. Optional mapping of Modbus Registers as Coil, Discrete, Input, Holding. BACnet Input, Value, Output objects for Analog, Binary, Multistate. Up to 1000 BACnet Objects and 1000 Modbus Holding Registers. Subscribe to COV on Changes from Modbus or BACnet. Connect BACnet IP Devices to a Modbus RTU or TCP Network. The SNMP agent (server) also has the ability to send traps on threshold rules set by the user. Configured to go the other way, the SPX-B will continuously poll objects in other BACnet devices and make that data accessible as Modbus registers for other Modbus masters polling the SPX-B.Īn available variation of the SPX-B also includes an SNMP client and server that translates and shares data between BACnet IP and SNMP devices. The SPX-B will continuously poll Modbus registers in TCP or RTU devices and make that data accessible as BACnet objects. The Modbus to BACnet IP gateway may be both Modbus TCP client and server at the same time, and can be configured to also be a Modbus RTU master or slave that runs independently of Modbus TCP. The Modbus to BACnet IP gateway acts as a translator between the two protocols. BACnet objects may be read as Modbus registers, and Modbus registers may be read as BACnet objects. The Babel Buster SPX-B Modbus to BACnet IP gateway allows Modbus devices to communicate with BACnet IP devices.
