2. You can find the part assigned to the respective index
of the I&M data under the associated data record number (see table below:
Configuration
of the I&M-data
).
All data records which contain I&M data have a length of 64 bytes.
The data records are structured in accordance with the following principle.
Table 8- 10 Data record structure with I&M data
Contents Length (bytes) Coding (hex)

Configuration of the I&M-data
The data structure of the I&M data corresponds to the specifications of the PROFIBUS
Guideline - Order No. 3.502, Version 1.1 May 2003.
Table 8- 11 Configuration of the I&M-data
I&M data Access Default Description
Identification data 0: Index 1 (data record 231)
MANUFACTURER_ID read (2 bytes) 2A hex (= 42 dec) This is where the name of the manufacturer is
saved. (42 dec = SIEMENS AG)
ORDER_ID read (20 Byte) depending on the
module
This is where the order number of the module is
saved.
SERIAL_NUMBER read (16 Byte) depending on the
module
Storage location of the module's serial number.
The number allows the unambiguous identification
of the module.
HARDWARE_REVISION read (2 bytes) depending on the
module
This is where the version of the module is saved.
Increments when the version number or firmware
of the module alters.
SOFTWARE_REVISION read (4 Byte) Firmware version Shows the module's firmware version.
If the firmware version increments, then the
version of the module also increases
(HARDWARE_REVISION).
REVISION_COUNTER read (2 bytes) 0000 hex reserved
PROFILE_ID read (2 bytes) F600 hex Generic device
PROFILE_SPECIFIC_TYPE read (2 bytes) 0005 hex on interface modules
IM_VERSION read (2 bytes) 0101 hex Shows the I&M data version.
(0101 hex = Version 1.1)
