Byte X+3 cannot be used if "4-byte mode" is set, as the bus coupler only supports 24 valve solenoids.

Output data section in the controller

The DDL address determines the position of the output data in
the data range of the bus coupler, and thus the position in the
address range in the controller.
If the address 0 (automatic addressing) is set, the VS will act like
a valve unit if it only has output modules. The VS will act like a
combination module if it has input modules.
The valve system occupies 1 to 4 bytes in the output section of
the controller, depending on the set length. The output modules
occupy the last bytes (see the following table).
