BODAS CB-ME, CL-API and FlashingReference Updates

We updated the BODAS CB-ME, CL-API and FlashingReference with new features and improved usability for the unified basic solution for Machinery Regulation (MR) and Cyber Resilience Act (CRA) compliance.

Remark: The implementation the CRA basic security solution in your project is optional and depends on your Threat Assessment and Risk Analysis (TARA) - see myBODAS Community.

CB-ME (Packages _260619)

RC5-6/40 (V01.11.00), RC18-12/40 + RC27-18/40 (V03.12.00) & RC18-12E/40 + RC27-18E/40 (V01.05.00)

• CAN Channel UDS Request Handling: CB-ME now responds to UDS requests on a single CAN channel, utilizing the CAN ID and baud rate configured by the ASW through NVM shared configuration, regardless of whether the CB-ME hex file or CL-API hex file is flashed to the ECU.

• One-Shot Password Provisioning and Update via keyfile: A new security feature, one-shot operation, is now available for managing passwords via keyfile. When enabled, this mechanism permanently and irreversibly restricts any further password updates through the keyfile.

For further details, refer RC Customer Manual 40.s/ml300-bs (and all CRA patch workflows).

Limitations:

• This CB-ME is compatible with BSW 1.29-bs (workflows 40.ml290-bs, 40.ml290-bs.rts) or another basic security (-bs) patched version of the older workflows (-bs). However, One-Shot Password Provisioning and Update will not be available.

• This CB-ME is incompatible with BODAS Secure Sign 0.2.2, please update to BODAS Secure Sign 1.0.3

Flashing Reference for RC40-Family has been updated accordingly. The new version is availble in myRexorth --> 23_FlashingReference, please contact your Sales Representative or our Onboarding Team.

CL-API (Packages _260619)

RC5-6/40 (V01.11.00), RC18-12/40 + RC27-18/40 (V03.12.00)

• Signature and Certificate Support: Memory and linker file configurations have been updated to support signature and certificate implementation by the CLAPI application.

Documentation:

• The CL-API manual has been updated with additional description for clnvm_readBlock regarding NVM RAM mirror behavior during startup.

• The error codes provided to the callback cluds_registerErrorCallback() are described separately.

Thank you!

BODAS Secure Sign Tool (0.2.2)

Remark: Signing the series software (hex-file) with the BODAS Secure Sign Tool is a requirement depending on whether your product is affected by the CRA/MR or your TARA requires it.

The BODAS Secure Sign CLI is a command-line tool that secures the firmware update process for BODAS embedded controllers. It ensures that:

• Only authorized firmware can be flashed onto controllers (code signing

• Only authorized users can produce signed firmware artifacts.

The tool manages the complete lifecycle from initial project setup through keyFile generation, firmware signing, user management, and root key rotation. 

Thank you!

With the introduction of the latest workflow 40.sml290-bs.rts for the CODESYS developer with did a huge feature shift:

• the BSW features are fully allied with the C-workflows

• there is one version of IDE v3.5.21 for all Codesys Rexroth Controllers

• Forcing / Writing variables during monitoring is now supported.

• Flashing from CODESYS IDE is possible

Therefore, we decided to disable the workflows older than 40.sml280.rts on 30.06.2026. Affected are: s151e.rts, ml190.rts, ml230.rts, s240.rts, s242.rts, ml232a.rts.

After 30.06.2026 you will NOT be able to:

• create new projects

• modify the current projects

• build any projects

We kindly ask you to migrate your projects to the latest workflows, see the Release Notes in easyConfig or the How to migrate / upgrade the RTS / CODESYS projects to 40.sml290-bs.rts guide.
