Does anyone know if the freemodbus library can be used as Modbus TCP and RTU at the same time?

I've found this port for mbed.

Thanks!

Hi Gonzalo, I'm also trying to compile this modbusTCP_Modified program with my LPC4088. But still NO luck on success when compile. If you have the working program appreciate if you can share with me :).

For the Modbus TCP + RTU at the same time, what i can suggest u is converting the modbus RTU to modbus TCP using converter such as Moxa Mgate (http://www.moxa.com/product/MGate_MB3180_3280_3480.htm). Normally we use that method :) More easy to manage where all modbus link is manage at network switch.

Hi everyone, I succesfully compiled and got working this example in a LPC1768 board but this MODBUS porting is using the deprecated Ethernet interface implementation Ethernetnetif, does anybody tried to port the FreeMODBUS using the new official Ethernet interface implementatión? if so i would appreciate any help about it.
