Parameter description
Note
The SIMOTION identifiers have changed as of V4.0.
You can find a comparison of SIMOTION and SIMATIC names in the Appendix SIMOTION
and SIMATIC names (Page 51).
The busy parameter must not be overwritten by the user. It is supplied and checked by the
function block, and must be supplied with a global variable created by the user only when the
respective function block is called. This parameter coordinates the individual function blocks
for the POSMO A. This ensures that no more than one function block can access a POSMO A
at the same time.
