WIFI Remote IP during MODBUS communication

Recommended Posts

Hi I am trying to do a MC to MC communication using modbus.

I assigned static IP's to both my MC's.

WiFiServer MbServer(MB_PORT);
WiFiClient client = MbServer.available();

        ///Do something//////

My question here is, Is there are way I can check the senders IP address before reading modbus packed data in the loop.

Because the receiver MC can be jammed with high data throughput as its a open connection (i.e anyone can send data to the MC by knowing its IP address). I want to read the senders IP before doing any data processing.

I know using UDP protocol we can use RemoteIP(). Is there anything similar in this case.

For sending and receiving MODBUS, im using the attached libraries.
