Abstract
A diagnostic system and method for detecting retardation of a object controlled by a programmable controller. The system may include a microprocessor system with a keyboard, a printer, a memory card, and a telecommunications line which is connected to one or more programmable controllers. This system reads operational commands and signals, representing the completion of an operation, through the telecommunications line. If any retardation occurs, the diagnostic system fetches a series of operation commands, and identifies the logical address where retardation occurs.
