PROBLEM TO BE SOLVED: To improve pressure on a memory resource by enabling a monitoring terminal to acquire a control logic diagram when abnormality occurs.SOLUTION: A controller 3 stores control logic diagrams describing control logic in a control logic diagram storage unit 100. In occurrence of abnormality, when an abnormality detection and transmission processing unit 150 of the controller 3 detects an abnormality signal generated by a control target apparatus 5, the abnormality detection and transmission processing unit 150 transmits corresponding pages of the control logic diagram that describe a passage of the abnormality signal, an abnormality message indicating details of abnormality, etc. to a monitoring terminal 2. The monitoring terminal 2 displays the corresponding pages of control logic diagram that are acquired from the controller 3 and describe the passage of abnormality signal with the abnormality message, etc. on a monitor of the monitoring terminal. |
