MODBUS TCP Library

[wireguy]

Has anyone found a good modbus slave library that can handle function 2 read inputs? The mudbus library doesn’t handle that function. Seems odd that controllino hasn’t made their own modbus library.

Hello,

have you tried the official Arduino Modbus TCP library ? We do not need to write our own library, because the CONTROLLINO is compatible with the Arduino boards – in this case CONTROLLINO MAXI/MEGA = Arduino Mega/Mega2560 + Ethernet Shield (the first version with Wiznet W5100).

Please, share with us the results!

Thanks,

Lukas
