Brief description

General
A synchronized action consists of a series of related statements within a part program that is
called cyclically in the interpolation cycle synchronously to the machining blocks.
A synchronized action is essentially divided into two parts, the optional condition and the
obligatory action part. The time at which the actions are executed can be made dependent
on a specific system state using the condition part. The conditions are evaluated cyclically in
the interpolation cycle. The actions are then a reaction to user-definable system states. Their
execution is not bound to block limits.
Furthermore, the validity of the synchronized action (non-modal, modal or static) and the
frequency of the execution of the actions (once, repeatedly) can be defined.
Examples of permissible actions
● Output of auxiliary functions to PLC
● Writing and reading of main run variables
● Traversing of positioning axes
● Activation of synchronous procedures, such as:
● Activation of technology cycles
● Calculation of function values
● Tool offsets
● Activating/deactivating couplings
● Measuring
● Enabling/disabling of synchronized actions
