Output of cam signals

13.3.1

Activating

The status of the cam (cam signals) can be output to the PLC as well as to the NC I/O.
Activation of cam signal output
The output of cam signals of an axis is activated via the 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 using the following
NC/PLC interface signal:
DB31, ... DBX62.0 (cams active)
Note
The activation can be linked with other conditions by the PLC user (e.g. axis referenced, reset
active).
13.3.2

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.
