4. The original Modbus specification included two possible transmission modes ASCII and RTU Modbus RTU mode is the most common implementation using binary coding and CRC error checking Modbus ASCII messages though somewhat more readable because they use ASCII characters is less efficient and uses less effective LRC error checking ASCII mode uses ASCII characters to begin and end messages whereas RTU uses time gaps 3 5 character times of silence for framing The two modes are incompatible so a device configured for ASCII mode cannot communicate with one using RTU All Modbus communications are initiated by Modbus masters using a polling query response format The master can send broadcast messages using a slave address of 0 which all slaves accept but do not reply to More commonly the master polls individual slaves sequentially In each poll it sends a message containing a device address followed by a function code any data that maybe required and an error check field The addressed slave responds with a similar message structure Typically it repeats back its address and the function code and then sends a field indicating the number of bytes of data it is sending followed by the data and the error check field Slave addresses can range from 1 to 247 Function codes include several common ones typically used in all applications and additional ones that may be implemented in specific cases Common function codes include Read Coil S
