Example for calling subroutine 45
3.19 Subroutine 46 - PI_SERVICE (Asynchronous Subroutine Program)
Purpose
Subroutine 46 is for realizing functions like ASUP (Asynchronous Subroutine Program),
deleting a password and reading current tool number. ASUP function means the execution of
PLCASUP1.SPF or PLCASUP2.SPF called by the PLC. SINUMERIK 808D provides two
ASUPs for the PLC. The two ASUPs can not be simultaneously executed, and the
PLCASUP1.SPF has a higher priority over the PLCASUP2.SPF.
In a program, firstly you can initialize the ASUP1 and ASUP2 by setting "PI index"
(DB1200.DBB4001) and "NCK read/write start" (DB1200.DBX4000.0), and then use a rising
edge to trigger "ASUP1 start" (DB3400.DBX0.0) and "ASUP2 start" (DB3400.DBX1.0).

Note
Important!
The SINUMERIK 808D provides two user ASUPs. In the sample application, ASUP1 is used
for manual tool change and ASUP2 is used for the MANUAL MACHINE of the workpiece on
a turning machine with the Manual Machine Plus function.
