Modbus to PA Gateway Working Principle
G0307 Modbus to PA gateway is a device supporting Modbus RTU protocol and PROFIBUS PA protocol. As the PROFIBUS PA slave device, it can make 4 Modbus slave devices connect to PROFIBUS PA network.
G0307 Modbus to PA gateway includes 1 physical block, 16 function blocks and 1 Modbus transducer block. Modbus transducer block includes 4 AIs, 4 AOs, 4 DIs and 4 DOs. The data (Modbus device data) can establish connection with function blocks via channels to realize protocol convert function.
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.
