Technology cycles are started as soon as their
conditions are fulfilled. In the case of positioning
axes, several interpolation cycles are necessary for
their execution. Other functions (OVR) are executed
in one cycle.
In the technology cycle, blocks are executed in
sequence.
Notes
If actions are called in the same interpolation cycle
that are mutually exclusive, the action is started that
is called from the synchronized action with the higher
ID number.
