Safety Laser Scanner with Monitoring Case Switching on an S7-1500
https://support.industry.siemens.com/cs/document/58804919/safety-laser-scanner-with-monitoring-case-switching-on-an-s7-1500
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.
