PRESET SINGLE REGISTER (FUNCTION CODE 06)
Function 06 allows the user to modify the contents of a holding register. Any holding register that exists
within the controller can have its contents changed by this message. The values are provided in binary up to
the maximum capacity of the controller. Unused high-order bits must be set to zero. When used with slave
address 00, all slave controllers will load the specified register with the contents specified.
