NOTICE!
When CODESYS Safety is started for the first time in the Automation
Builder project, you will be asked to manually confirm included safety
library identification data (version number and CRC). After this, safety
library identification data are saved in the project.
If you change the safety library content and replace it on your hard
disk, the next time you start CODESYS Safety you will be informed
that one of the safety libraries changed. In the properties window for
safety libraries you will still observe an initially saved CRC value.
However, when you compile the project, you will get a CRC error mes-
sage because of the changed library and the project will not be com-
piled.
To compile the project successfully, manually delete the selected
safety library and add a new safety library with a new CRC. The new
safety library with new CRC will be accepted and no compilation error
will be shown.
