    11.3. Discrete Inputs There are no Discrete Inputs for Air-To-Air systems. 11.4. Coils Coils are read using function code 01 and written to using either function code 05 or 15. Function code 05 is used when writing to a single coil register, function code 15 is used for writing to multiple coil registers in the same command. Note the values of all Coil registers have corresponding Holding registers which can be used instead.
