Abstract: A method of inspecting a programmable logic controller (PLC) control logic using a graphic neural network (GNN) generally includes three operations: a data preprocessing operation for a GNN, an operation of predicting whether tags are connected, and an operation of verifying suitability of edge connections between tags. As a result, a graph is generated from a PLC control logic and input to a link prediction model to find an incorrect connection in the PLC control logic. Subsequently, a result graph output through the link prediction is input to a trained model to verify edge connection suitability between tags. Then, it may be finally verified whether tags are connected in the PLC control logic.
