Error (Safety Library Export): Adding a time stamp to the signature of the safety inventory failed.

Note
Currently, this error can only be reported when releasing a library of safety-related C function block POUs with loadable C function code.

While releasing a library with safety-related IEC data (*.pcwlx), a time stamp is added to the signature in the safety inventory of the released library. Using this time stamp, it is verified whether the code signing certificate was valid at the time the library is released.

PLCnext Engineer retrieves this time stamp from a time stamp server. The reason is that a time stamp server cannot be manipulated (in contrast to the PC system time, for example).

This error is reported because it was not possible to write the time stamp to the inventory. Possibly, the time stamp server could not be connected.

Remedy

  1. Make sure that your PC, where PLCnext Engineer runs, has Internet access.
  2. If your Internet connection is working correctly, possibly the time stamp server is unavailable.
    Retry to release the library later.

If the error is then still reported, contact the technical support of Phoenix Contact.
