Asynchronous subprograms ASUB

Asynchronous subprograms ASUB

Function

An asynchronous subprogram is a CNC program which can be started in response to an external event (e.g. a digital input) or from the PLC.

Inputs are allocated to subprograms and activated by programming SETINT.

Multiple asynchronous subprograms must be assigned different priorities PRIO so that they can be processed in a certain order.

Benefits

• Immediate cancellation of the CNC block currently being executed when the external event occurs
• The CNC program can be continued later at the point of interruption
• ASUBs can be disabled and enabled in the CNC program: DISABLE/ENABLE

Requirement:

• High-speed CNC inputs/outputs

→ Interrupt routines with fast retraction from the contour (option M42)
