A Modbus RTU/Modbus TCP gateway is connected to 10 devices. SCADA PC is connected to the gateway through an existing LAN.
I need to calculate the bandwidth required in the LAN to carry data between the gateway and SCADA PC.
Bus Baud rate is 9600 bps.
I believe that the bandwidth will be limited to 9600 bps since the gateway is not buffering data.
But I should include the headers of TCP/IP packets also in the calculation?
Would you please help me on that.
I don't have any idea how Modbus RTU data is encapsulated in the Modbus TCP packets.
Thanks in advance
