Gateway Principle

As Modbus master, G0307 Modbus to PA gateway shall do the communication with Modbus slave, and exchange Modbus transducer block parameter data and function block, so that it connect Modbus slave to PROFIBUS system.

Gateway Configuration

Topology Connection

A PROFIBUS PAnetwork topology supports multiple network topology connections, shown as picture. The PAdevicebus connection is shown in picture, the bus ends is connected with terminal matched resistanceto ensure signal quality. The maximum length is 1900m, it shall be prolonged to 10km with repeaters.
