Query Of The Rangeindex In Case Of "Profibus-I/O In Write Direction - Siemens SINUMERIK 840D sl Function Manual

1.5.2.3

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)
Programming
before an access query the status of RangeIndex = 5
N3
N5
N10
N15
N20
Query, whether all configured ranges/slots are valid
