Starting ASUBs

14.6.5.1

General

From the PLC, interrupt 1 or 2 can be initiated on the NC, in principle, at any point in time. As
a consequence, the program currently being processed in the NC is interrupted, and the
interrupt program assigned to the interrupt executed:
● Interrupt 1: _N_CMD_DIR/PLCASUP1.SPF
● Interrupt 2: _N_CMD_DIR/PLCASUP2.SPF
Note
A start signal must not be set in the following cases:
● PI service "ASUB" has not been completed yet.
● DB2600.DBX0.1 == 1 (emergency stop)
● The request "Channel reset" is still active in the channel.
The ASUB can only be started again when the channel is in the "Reset" state AND
DB3300.DBX3.7 == 1 (channel state reset).
