Unity Pro
Unity Pro XLS provides the option of performing an auto-test to verify that the
software components installed have not been corrupted, for example, due to a hard
disk failure. This auto-test is based on a CRC calculation.
Unity Pro XLS checks the version and CRC:

Unity Pro XLS auto-tests are performed upon request by the user, for example:

PLC
With Unity Pro XLS, every binary file generated for a safety project features a version
management field that provides the date and time when it was generated.
This information is useful for checking the project.
It is possible to download a safety project from the PLC to Unity Pro XLS under the
following conditions:

The unrestricted memory area contains bits and words that are not protected against
write operations from external equipment such as HMI terminals, PLCs, etc.

in conjunction with specific function blocks: S_MOVE_BIT and S_MOVE_WORD.
In the edit phase first and then in the generation phase, Unity Pro XLS checks to
make sure than only data from the unrestricted memory area are used at the input of
the function blocks S_MOVE_BIT and S_MOVE_WORD.
Unity Pro XLS provides a useful list of cross references, allowing easy identification
of the way variables are used and verification of the application of this rule.
Note: For safety applications, it is common practice to verify the correct transfer of data by writing
