Method of searching for anomalies in the firmware program of an automation module

摘要

The system has a connecting cable (3) including a hardware identification part (300) i.e. strap, and connecting a specific input/output module (1) of a programmable logic controller with a computer terminal (2) e.g. personal computer. The module has software identification units to identify the cable when the cable is connected on a connector (13) of the module. A non-volatile memory (12) e.g. electrically EPROM, of the module stores a software component (121) i.e. ROM monitor, co-operating with software tools (220) of the terminal to search anomalies in a firmware (120) stored in the module. An independent claim is also included for a method of searching an anomaly in a firmware stored in a non-volatile memory of a module of a programmable logic controller.
