A DataMatrix code has been lasered onto 3RB3 solid-state overload relay devices under the
label (size S2 only).
The 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:
● Article number
● Serial number
● If applicable, MAC address
This information is stored in the following format in the DataMatrix code:
1P Article number + S Location / Date Serial number
Data
identifier
User content Separator User content Separator User

User content
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.
