Querying System Variables - Siemens SINUMERIK 828D Function Manual

Status
Auxiliary function is managed by the PLC and has been
directly applied by the PLC.
Auxiliary function is managed by the PLC, and the function
acknowledgement has taken place.
Display update
The display is organized in such a way that the collected auxiliary functions are always displayed first, before
those that were managed by the PLC and before those that were managed by the NC. A collected auxiliary
function is marked as collected until it has been output from the NCK to the PLC. PLC-managed auxiliary
functions are retained until they are displaced by another auxiliary function. In the case of a reset, only the
collected auxiliary functions and the NC-managed auxiliary functions are deleted.
