Starting ASUBs

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

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).

● Bit 0 = 1: Request to start the ASUB, which is assigned to INT1.

● Bit 0 = 0: Reset the ASUB request after acknowledgement in the result interface DBB1000.

● Bit 0 = 1: Request to start the ASUB, which is assigned to INT2.

● Bit 0 = 0: Reset the ASUB request after acknowledgement in the result interface DBB1001.
