PEARL (Process and Experiment Automation Real-Time Language) is a high-level industrial programming language for real-time process control. PEARL features state models, a mechanism for handling asynchronous events, and distributed systems capabilities. The language was standardized by the International Electrotechnical Commission (IEC) in 1993 as part of the IEC 61588 standard, succeeding its predecessor ALGOL. PEARL's design aims to provide safety-critical applications with a level of dependability equivalent to that of hardware-based logic systems at reduced costs and development timescales. It continues to be used in legacy systems within industries such as automotive manufacturing and power plant automation where reliability is paramount.
