ASUP function
The ASUP function means the execution of the program PLCASUP1.SPF or PLCASUP2.SPF called by the PLC. The two
ASUPs cannot be simultaneously executed, and PLCASUP1.SPF has a higher priority over PLCASUP2.SPF.
In a PLC program, firstly you must initialize the ASUP 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) or "ASUP2 start"
(DB3400.DBX1.0).
The control system provides two default ASUPs for the PLC. 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.
You can also use your own ASUPs as required. To do so, you must first place your programs (PLCASUP1.SPF and
PLCASUP2.SPF) in the manufacturer cycle directory (N:\CMA), and then set "PI index" (DB1200.DBB4001) to 1 (ASUP1)/2
(ASUP2).
