Display of the current encryption version

The current TwinCAT version uses the current encryption version. For TwinCAT build 4022.x, this was version 1.4 at the time this documentation was created.

Previously, versions 1.0-1.3 were used (build 4020.x). The use of these encryption versions is strongly discouraged. Always use the latest available version.

A prerequisite for secure encryption is the use of a current TwinCAT version with the current encryption version!
