:
The position to be written to must have been previously configured as an output, otherwise this
command will have no effect.
The POSITION value is a point offset starting from the value in the ADDRESS parameter. The point
number in the POSITION parameter can range from 0 to 511 if the ADDRESS parameter is 0. An
error will be returned if the values in these parameters exceed the limits.
