This function block asynchronously reads general objects
of up to 4 bytes from the object dictionary of the SAB if
the Enable input is set. For the index and the sub-index of
the parameters, see chapter 8 SAB Parameter Description.
The output data needs to be read from the device and is
therefore not immediately available.
