Design of the overall system
Design of the overall system
The overall system comprises a total of three components:
•
Safety system (from SICK)
•
Robot
•
Safety command devices
The safety system ends at all inputs and outputs that are not used to wire the compo‐
nents of the safety system.
The safety-related machine controller parts (SRP/CS) are distributed among the safety
system and robot controller.

Functionality
Overview
The safety system detects people in a monitored area. When a person approaches the
robot, the safety system decreases the robot speed until it comes to a standstill.
Functionality
The safety laser scanner monitors the access area of the hazardous area with several
protective fields. When a person approaches the robot, the protective fields are inter‐
rupted one after another.
The robot speed is reduced if the first protective field is interrupted. If the second pro‐
tective field is interrupted, the safety system triggers a protective stop.
If the person moves away from the robot, the protective fields become free again one
after another. Restarting the robot is possible when all of the protective fields are free.
The safety system monitors the sequence in which each protective field is interrupted
and becomes free again. A valid sequence leads to an automated restart.
