Safety Laser Scanner with Monitoring Case Switching on an S7-1500

  • Entry
  • Associated product(s)
An assembly cell with a robot has two workstations that can alternately be freely accessed by an operator. During operation, the situation changes due to the movement of the robot: The hazardous area becomes the working area and vice versa.

The following monitoring cases are defined:

  • Case 1: While the robot works at station 1, 
the operator can load or unload at station 2.

  • Case 2: While the robot works at station 2, 
the operator can load or unload at station 1.

  



To monitor this assembly cell, a SICK safety laser scanner S3000 is to be used in conjunction with a fail-safe SIMATIC S7-1500 (F-CPU).

The laser scanner monitors a danger area, depending on the robot’s position, and shuts down its safe OSSD output (Output Signal Switching Device) upon entering the protective field, which causes the F-CPU to shut down the robot.



F-CPU and laser scanner communicate via PROFINET with the error-secure “PROFIsafe” profile. The robot’s position is detected via two sensors (e.g. SIRIUS position switch).
