摘要：

In this paper, is developed a diagnosis algorithm, which can be used when a PLC is malfunctioning or has a fault. The algorithm helps operators diagnose a failed system to minimize recovery time when a production line or system is stopped. It is shown that the proposed algorithm can diagnose faults which a typical self-diagnostics in the commercially available PLC cannot. Copyright (C) 1998 IFAC.
