Provide FF H1 communication ability to Modbus device Support standard DD or EDD specification (FF H1) Electrical interface connected with Modbus device supports TTL level, RS485 and RS232 G0313 Modbus to FF Gateway is a gateway device of Modbus protocol and FF protocol developed by Microcyber. As Modbus master station, G0313 Modbus to FF Gateway communicates with Modbus-RTU device via RS485 interface, and it can convert the data of Modbus-RTU device to FF device variable output. G0313 Modbus to FF Gateway size is 99Ã?22.5Ã?114.5mm, and supports standard DIN rail installation. There is a 3-bit DIP switch for G0313 Modbus to FF Gateway, shown as the following Figure. SIM: Simulation switch, used for simulation function. WP: Write protection, all the write operation for FF smart pressure transmitter shall be refused, which avoid data modification at random. RST: Reset, reset device date to factory original. Power off the device at first, and made the switch at ON, and then power on the device, the device shall be reset to factory original. 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. 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 devices data into transducer blocks parameters via Modbus register, and provides data support for FF system via channels between variables and AI, AO, DI and DO function blocks.
