Researchers have introduced PLCWorld, a new benchmark designed to evaluate the performance of large language models (LLMs) in generating programs for programmable logic controllers (PLCs). This benchmark includes 100 synthetic tasks and 473 task-condition pairs across motion control and material handling, with a focus on assessing task success and safety violations in closed-loop plant simulations. Initial evaluations show that GPT-5.5 achieved 82.70% task success on easy cases but dropped to 25.10% on harder cases, highlighting the challenges LLMs face in complex industrial control scenarios.
