TwinCAT 3 OEM certificates

A TwinCAT OEM certificate signed by Beckhoff is required in order to be able to use the application software protection functions.

The TwinCAT OEM certificate is exclusively intended for use together with TwinCAT.

With TwinCAT Build 4024, the TwinCAT OEM certificate version TC0008 can additionally be used to sign TwinCAT *.tmx files created with TwinCAT 3 in C++.

With the launch of TwinCAT 3.1 Build 4024, several new features relating to TwinCAT OEM certificates were introduced, compared to Build 4022:

• Update to a newer encryption version for the internal certificate data
• Introduction of an extended certificate version TC0008, with which C++ TwinCAT driver software created in TwinCAT 3 can also be signed
• This certificate version requires secure validation of the applicant data, since it is used in the Windows environment.
• The process of applying for a TwinCAT OEM certificate was modified for this purpose. All OEM certificates must be officially ordered to validate address and contact information. (However, the issuing of a TwinCAT OEM certificate remains free of charge.)
• TwinCAT OEM Certificates Extended Validation (TC0008) are only issued to existing Beckhoff customers.
