2.12.16 FC 9: ASUB startup of asynchronous subprograms
Description of functions
The FC ASUB can be used to trigger any functions in the NC. Before an ASUB can be
started from the PLC, it must have been selected and parameterized by an NC program or
by FB 4 (PI service ASUB).
Once prepared in this way, it can be started at any time from the PLC. The NC program
running on the channel in question is interrupted by the asynchronous subprogram. Only one
ASUB can be started in the same channel at a time. If the start parameter is set to logical 1
for two FC 9s within one PLC cycle, the ASUBs are started in the sequence in which they
are called.
