Fc9: Asub - Start Of Asynchronous Subroutines - Siemens SINUMERIK 840D sl Function Manual

Status definition
A general rule for the acknowledgement status is that the status information 1 to 7 leads to the
termination of the command. If FC8 receives one of the statuses, the "Interface active bit" of
the interface specified in FC8 is reset to "0" (see also interface lists DB 71 to DB 73), thus
completing the operation. The response is different in the case of status information 103 to
105. When the FC8 receives one of these items of status information, the "Interface active bit"
of this interface remains at "1". Further processing is required by the user program in the PLC
(e.g. continuation of magazine positioning). This item of status information is generally used
to transfer changes in position of one or both tools while the operation is still in progress.
Call example

FC9: ASUB - start of asynchronous subroutines

Function
The block FC9 "ASUP" 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 FB4 (PI service ASUB). In this case, the channel and the interrupt numbers must match
the parameters in FC9.
