1.5 DataMatrix code
A DataMatrix code is lasered onto the lower terminal cover of all 3SK1-series safety relays.
DataMatrix codes are standardized in ISO/IEC 16022. The DataMatrix codes on Siemens
devices use ECC200 coding for powerful error correction.
The following device information is encoded in the DataMatrix codes as a bit stream:
● MLFB
● Serial number
● MAC address, if applicable
This information is stored in the following format in the DataMatrix code:
1P MLFB + S serial number
(+ 23S MAC address)
Data identifier Net content Separator
Note
The information content is displayed without spaces.
This machine-readable information simplifies and accelerates handling of the respective
devices.
As well as fast access to the serial numbers of the respective devices for unique
identification, the DataMatrix codes simplify communication with Siemens Technical Support.
The DataMatrix codes enable in particular extremely fast and convenient access to all the
device-specific information available on an MLFB in the SIEMENS Service&Support Portal,
such as operating instructions, manuals, data sheets, FAQs, etc..
We offer the SIEMENS Industry Support App free for this purpose. This can be used on
commercially available smartphones and tablet PCs.
The SIEMENS Industry Support App is available for iOS and Android-based terminal devices
and can be accessed via the following links:
