GuardLogix Configuration

Safety Logic Integration
There are different ways to provide a safety system for a CNC machining work cell. This toolkit provides an
example of a supervisory GuardLogix safety controller that provides safety control for the two gantry drives, an
EStop, a light curtain, and provides safety interlocking with the Dual Check Safety systems of the two CNC
systems.
Safety I/O
The safety interface between the GuardLogix controller and FANUC CNC Dual Check Safety systems is
accomplished through the safety I/O of both systems. For safety category 3 and 4, two output channels and two
input channels of GuardLogix I/O are connected to two input channels and two output channels of the Dual
Check Safety I/O, as illustrated in
Figure 18 .
Figure 18 - Safety I/O Example
This wiring interface is included in the system layout and wiring library within this toolkit. Refer to the Dual
Check I/O and 1791 Guard I/O drawings.
