Explanation: A Safety PLC is a type of PLC that is specifically designed to monitor and control safety-critical aspects of the industrial process. It is used to ensure that the process is operating within safe limits and to shut down the process in case of a safety issue. It can also trigger alarms to alert operators of potential safety hazards. Safety PLCs are commonly used in industrial processes such as chemical and petrochemical production, and power generation, where safety is a critical concern.
