Output Of Cam Signals To Nck I/Os In Position Control Cycle - Siemens SINUMERIK 840D sl Function Manual

Software cams, position switching signals (N3)
9.3 Output of cam signals
If no measuring system is selected or NC/PLC interface signal:
DB31, ... DBX2.0 (cam activation)
is set to 0,
then the following NC/PLC interface signals are also set to 0:
DB10 DBX110.0-113.7 (minus cam signals 1-32)
DB10 DBX114.0-117.7 (plus cam signals 1-32)
DB 31, ... DBX62.0 (Cam active)
9.3.3

Output of cam signals to NCK I/Os in position control cycle

Signal output in position control cycle
For the cams assigned to a hardware byte in machine data:
MD10470 SW_CAM_ASSIGN_FASTOUT_1
to
MD10473 SW_CAM_ASSIGN_FASTOUT_4,
the signal output takes place in the position control cycle.
The 4 onboard outputs on the NCU and a total of 32 optional external NCK outputs are
available as the digital outputs of the NCK I/Os.

Hardware assignment
The assignment to the hardware bytes used is made for each eight cam pairs in the following
general machine data:
MD10470 SW_CAM_ASSIGN_FASTOUT_1
MD10471 SW_CAM_ASSIGN_FASTOUT_2
MD10472 SW_CAM_ASSIGN_FASTOUT_3
MD10473 SW_CAM_ASSIGN_FASTOUT_4
Note
It is possible to define one HW byte for the output of eight minus cam signals and one HW
byte for the output of eight plus cam signals in each machine data.
In addition, the output of the cam signals can be inverted with the two machine data.
If the 2nd byte is not specified (= "0"), then the 8 cams are output as a logic operation of the
minus and plus cam signals via the 1st HW byte using the 1st inversion screen form.
