# Pre- and post-files

For this cycle there is a pre-file which must be called before this cycle and a post-file which is called after this cycle. These files are optional. If they do not exist, this step is skipped. As required, these files must therefore be created as a subroutine. Machine-specific adaptations, e.g. activation of the touch probe, can be carried out in the pre-file. The post-file can be used to process output variables, for example.

Pre- and post-files must have the following names:

- SysMeasToolPre
- SysMeasToolPost
