Page 11: Working Principle Of Modbus Tcp Master
Ethernet supports Modbus TCP master function, described as below: Data exchange of Modbus TCP and PROFIBUS DP of GT200-DP-MT is set up through “mapping”. There are two data buffer areas, one is PROFIBUS DP network input buffer and the other is PROFIBUS DP network output buffer. -
Page 12: Working Principle Of Modbus Tcp Slave
… … … … Data exchange of Modbus TCP and PROFIBUS DP of GT200-DP-MT is set up through “mapping”. There are two data buffer areas, one is PROFIBUS DP network input buffer and the other is PROFIBUS DP network output buffer. Network input and output buffer is all for PROFIBUS DP. When the gateway acts as Modbus TCP slave, Modbus write register command will write the read data to the network input buffer for PROFIBUS DP accessing. -
