摘要： A method of alarming an abnormal state of a line of an automated manufacturing system using a programmable logic controller (PLC) signal pattern is provided. The method includes obtaining a plurality of change sequences of a plurality of PLC signals for control of the line in a normal operating system by repeating a cycle for which the line is sequentially controlled by the PLC signals that are transmitted and received between a PLC and the line according to an operation of PLC internal logic; acquiring a reference sequence from a plurality of the change sequences, wherein the reference sequence indicates an order of change of a plurality of the PLC signals for control of the line in a normal operating state; and determining whether the line is in a normal operating state or an abnormal operating system based on whether or not the reference sequence is matched with a change sequence of a plurality of PLC signals for control of the line in use after the acquisition of the reference sequence, and outputting a determination result.
