The function code field of amessage contains 8 bits Valid function codes are in the range of 1 255 decimal The function code instructs the slave what kind of action to take Some examples are to read the status of a group of discrete inputs to read the data in a group of registers to write to an output coil or a group of registers or to read the diagnostic status of a slave When aslave responds to the master it uses the function code field to indicate either anormal response or that some type of error has occurred For a normal response the slave echoes the original function code In an error condition the slave echoes the original function code with its MSB set to a logic 1 The data field is constructed using sets of two hexadecimal digits in the range of 00 to FF According to the network s serial transmission mode these digits can be made of a pair of ASCII characters or from one RTU character The data field also contains additional information that the slave uses to execute the action defined by the function code This can include internal addresses quantity of items to be handled etc The data field of a response from a slave to a master contains the data requested if no error occurs If an error occurs the field contains an exception code that the master uses to determine the next action to be taken The data field can be nonexistent in certain types of messages Ethernet Communications Modules 3rd Edition Rev C 06 11
