Embedded PLC Simulation in Safety Laser Scanner Configuration Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Safety laser scanners require expert configuration and complex setup due to fieldbus protocols, making them difficult for untrained operators to test and validate configurations without external controllers.
Innovation Solution
An embedded solution within the safety laser scanner that emulates the behavior of an external controller, allowing users to test and validate configurations through a graphical user interface without the need for external equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fieldbus protocols are used for safety laser scanner communication, then system integration capability and safety data transmission are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent implements a simulator that replicates the behavior of external fieldbus controllers within the safety laser scanner itself. This copying approach allows the device to test and validate configurations internally without requiring actual external controllers, thereby maintaining fieldbus protocol capabilities while reducing operational complexity for users.
2Reliability
If fieldbus protocols are implemented, then safety data transmission and system integration are improved, but ease of operation and testing capability deteriorate
Solution Approach 1:
The safety laser scanner performs self-testing and self-validation through the embedded simulator that mimics external controller behavior. This self-service capability allows untrained operators to test configurations and validate settings without needing external testing equipment or expert knowledge of fieldbus protocols, while maintaining reliable safety data transmission capabilities.
3Adaptability or versatility
If external controllers are required for operation, then system functionality is maintained, but device complexity and operational difficulty increase
Solution Approach 1:
The simulator is pre-configured within the safety laser scanner to replicate various external controller behaviors before actual deployment. This preliminary action allows users to validate configurations, test communication protocols, and verify system functionality during factory setup or initial configuration without requiring actual external controllers, thereby reducing on-site setup complexity while maintaining full system functionality.

AI summary
The disclosure includes a safety laser scanner device having a features simulator embedded thereon. One or more processors having one or more embedded software applications may be operable to connect with an external controller during an operational mode, and to emulate behavior of the external controller during a test mode that is configured to test the SLS device and validate configuration settings without the use of an external controller. A related method includes operating a safety laser scanner to communicate input process images and output process images between a programmable logic controller (PLC) and the safety laser scanner during an operational mode, communicate input process images and output process images between an external computer running a graphical user interface (GUI) during a test mode, and operate embedded logic within the safety laser scanner operable to emulate behavior of the PLC during test mode without a connection to the PLC.
