PROFIBUS-I/O in read direction

Requirement
The S7-HW-configuration is already done.
Configuration for programming via part program/synchronous actions
● RangeIndex = 0 (NCK-internal configuration)
● as per S7-HW-configuration:
This results in the following configuration of the machine data:
MD10500 $MN_DPIO_LOGIC_ADDRESS_IN[0] = 456 (log. start address I/O-range)
MD10501 $MN_DPIO_RANGE_LENGTH_IN[0] = 32 (length of the I/O-range)
MD10502 $MN_DPIO_RANGE_ATTRIBUTE_IN[0]
Bit0 = 1 (Big-Endian-Format)
Bit2 = 0 (read possible via system variable and CC-binding)
Bit3 = 0 (Slot-lifespan-alarms issued)
Configuration for programming via CompileCycles
● RangeIndex = 1 (NCK-internal configuration)
● as per S7-HW-configuration:
This results in the following configuration of the machine data:
MD10500 $MN_DPIO_LOGIC_ADDRESS_IN[1] = 312 (log. start address I/O-range)
MD10501 $MN_DPIO_RANGE_LENGTH_IN[1] = 32 (length of the I/O-range)
MD10502 $MN_DPIO_RANGE_ATTRIBUTE_IN[1]
Bit0 = 1 (Big-Endian-Format)
Bit2 = 1 (read possible only via CC-binding)
Bit3 = 1 (Slot-lifespan-alarms suppressed)
