Siemens SINUMERIK 840Di Function Manual page 1099

The start parameter must be set to logic 0 by the user once the ASUB has been terminated
(Done) or if an error has occurred.
For the purpose of job processing, every FC ASUB required its own WORD parameter (Ref)
from the global user memory area. This parameter is for internal use only and must not be
changed by the user. Parameter Ref is initialized with the value 0 in the first OB 1 cycle and,
for this reason, every FC 9 must be called absolutely. Alternatively, the user can initialize
parameter "Ref" with a value of 0 during startup. This option makes conditional calls
possible. When a conditional call is activated by parameter "Start" = 1, it must remain active
until parameter "Done" has made the transition from 1 to 0.
Note
The function is initiated only with the LowHigh edge.
