This results in the following configuration of the machine data:
MD10510 $MN_DPIO_LOGIC_ADDRESS_OUT[5] = 1200 (log. start address I/O-range)
MD10511 $MN_DPIO_RANGE_LENGTH_OUT[5] = 0
(a single useful-data slot is to be used)
MD10512 $MN_DPIO_RANGE_ATTRIBUTE_OUT[5]
Bit0 = 1 (Big-Endian-Format)
Bit1 = 0 (writing only via system variable)
Bit3 = 0 (Slot-lifespan-alarms issued)
