Why need to use EtherCAT to Modbus TCP gateway solution?

Modbus TCP is NOT a real-time network, since the Modbus TCP/IP ADU (Application Data Unit) data is embedded inside the TCP/IP frames of standard Ethernet packets. Designers can use AX58200 EtherCAT to Modbus TCP Gateway solution to integrate Non-real-time Modbus TCP network (with longer than 100ms cycle time) into Real-time EtherCAT network (with less than 1ms cycle time)!!

AX58200 EtherCAT Slave Controller SoC supports two embedded Fast Ethernet PHY for EtherCAT network connection; AX58200 also supports another embedded Ethernet MAC controller, which can be connected with an external RMII Fast Ethernet PHY for Modbus TCP network connection.

AX58200 EtherCAT to Modbus TCP Gateway firmware can realize the gateway functionalities by parsing EtherCAT RxPDO, TxPDO and Modbus commands based on the pre-defined Modbus commands mapping table.

This AX58200 EtherCAT to Modbus TCP gateway demonstration uses AX58200 TwinCAT PLC Modbus TCP demo utility and Modbus TCP Server Simulator to demonstrate digital I/O remote control functionalities between EtherCAT and Modbus TCP networks.
