Query of the RangeIndex in case of "PROFIBUS-I/O in write direction"

Requirement
The S7-HW-configuration is already done.
Configuration for programming via part program/synchronous actions
● RangeIndex = 5 (NCK-internal configuration)
● as per S7-HW-configuration:
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)
68
– log. start address = 1200
– Slot length = 32 byte
– To be displayed in Big-Endian format
; read (16 bit) on RangeIndex=0, RangeOffset=0
; Big-Endian-format
; read (32 bit) on RangeIndex=0, RangeOffset=1
; Big-Endian-format
; read (32 bit) on RangeIndex=0, RangeOffset=8
; Big-Endian-format
; read (32 bit) on RangeIndex=0, RangeOffset=8
; Big-Endian-format
; indirect programming
; Cyclic reading;(per IPO cycle)
; Alarm 17030 because the RangeOffset is invalid.
; Alarm 17020 because this range is not defined.
; Alarm 17020 because this range of part program
; cannot be written.
; Alarm 17020 because RangeIndex >= max.
; available number of ranges.
