Modbus distance Maximum
modbus communication distance maximum

Modbus itself specifies no distances, as it doesn't even specify any particular physical layer. Modbus can be carried over any media, such as RS-485, RS-232 etc., and the distance limitations would then be the ones particular to that physical layer.
