Additional note
1. If a data alignment has not yet taken place (and the NCK
component is installed), a request is automatically issued in the
form of a message when the simulation is initialized. The user is
automatically informed of modifications to tool data.
2. The working cycles are loaded from the part program once on the
first call and remain active for all subsequent simulation sessions.
3. With the softkey "Compare cycles" you can load updated cycles
with a new timestamp in the simulation. Cycles with access
protection are always reloaded, irrespective of the timestamp. A
realignment is only necessary after changes have been made to
the cycles.
4. It is recommended to set MD11210=0 "Adjust all machine data".
