Modbus to FF Gateway Working Principle


Modbus to FF gateway is a gateway device supporting Modbus and FF protocol. As FF device, it can communicate with Modbus devices, read Modbus data to FF device by simply configuration, and transfer data to control system through FF bus. System Wiring Diagram of Modbus to FF Gateway is shown in picture:


Modbus to FF Gateway supports 4 Modbus slave devices, 8 groups of analog input output and discrete input output parameters, totally 32 channels provided. It configures Modbus device’s data into transducer block’s parameters via Modbus register, and provides data support for FF system via channels between variables and AI, AO, DI and DO function blocks. Principle Diagram for MODBUS to FF Gateway is shown in picture.

Configuration of Gateway


FF transmitter supports many net topologies shown as Topology of FF Bus The bus connection of FF instrument is shown inFF Bus Connection, in order to ensure the bus signal quality, the terminal matching resistances should be connected to the 2 ends of the bus. The bus maximum length is 1900m, with a repeater, the length can be extended to 10 kilometers.
