The DFI302 is a programable bridge able to integrate Modbus (RTU & TCP/IP), Foundation Fieldbus (H1 & HSE), HART and conventional I/O in one unit. It supports Function Block programing and can be configured as either a Modbus Master or Modbus Slave.
Modbus, Modbus TCP/IP
Integral part of SYSTEM302; single integrated unit of interface, linking device, bridge, controller, gateway, Fieldbus power supply and distributed I/O subsystem; tight integration with intelligent devices and software from multiple manufacturers due to use of open standards; Connects to existing equipment through conventional I/O and Modbus communication; Full redundancy and fault isolation for high safety and uninterrupted operation.
