and message trailer (ASCII only) since these are specific to the data transfer mode.
 The Gould/Modicon Modbus protocol specifies the address range for each function
code. However. the FloBoss S600+ Modbus configuration is flexible in that it does
not have to adhere to these address ranges although they are stated below for
clarity.
