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

N3: Software cams, position switching cycles - only 840D sl
9.3 Output of cam signals
Note
The activation can be linked with other conditions by the PLC user (e.g. axis referenced, reset
active).
9.3.2

Output of cam signals to PLC

Output to PLC
The status of the cam signals for all machine axes with activated software cams is output to
the PLC.
The status is output in the IPO cycle and is transferred to the PLC asynchronously.
Minus cam signals
The status of the minus cam signals is entered into the following NC/PLC interface signals:
DB10 DBX110.0 to 113.7 (minus cam signal 1 to 32)
Plus cam signals
The status of the plus cam signals is entered into the following NC/PLC interface signals:
DB10 DBX114.0 to 117.7 (plus cam signals 1 to 32)
Note
If no measuring system has been 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)
● DB31, ... DBX62.0 (cams active)
9.3.3

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

Signal output in position control cycle
For cams assigned to an HW byte via machine data MD10470 to MD10473 (see Section
"Hardware assignment"), the signal is output in the position control cycle.
