Output of cam signals

9.3.1

Activating

The status of the cam (cam signals) can be output to the PLC as well as to the NCK I/Os.
Activation of cam signal output
The output of cam signals for an axis is activated via
axis-specific NC/PLC interface signal:
DB31, ... DBX2.0 (cam activation).
Check-back signal to PLC
The successful activation of all cams of an axis is signaled back to the PLC via
axis-specific NC/PLC interface signal:
DB31, ... DBX62.0 (cam active).
Note
The activation can be associated 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 in the general
NC/PLC interface signals:
DB10 DBX110.0 to 113.7 (minus cam signals 1 to 32).
Plus cam signals
The status of the plus cam signals is entered in the general
NC/PLC interface signals:
DB10 DBX114.0 to 117.7 (plus cam signals 1 to 32).
