Three examples of safety-critical applications in PLC control include: 1. Emergency shutdown systems in industrial plants, where PLCs are used to quickly and safely shut down equipment in the event of a hazardous situation. 2. Automated safety systems in transportation, such as railway signaling systems that use PLCs to control the safe operation of trains and prevent collisions. 3.
