PROBLEM TO BE SOLVED: To provide an output of maintenance diagnosis information and a diagnosis information display device capable of outputting and displaying the maintenance diagnosis information even in a state that a CPU is not operated.SOLUTION: A control device 100 includes a diagnosis information output circuit 140 for determining an operation state of a control device 100 on the basis of various signals, generating diagnosis information on the basis of the determination result, converting the generated diagnosis information into an electric signal, and outputting the electric signal to a diagnosis information recording display device 200 via a power supply interface of a general purpose interface 150. A user can confirm the output diagnosis information and easily grasp the operation state of the control device 100 by using the power supply interface even in a state that a CPU 110 or the like of the control device 100 is not normally operated and the general purpose interface 150 cannot be controlled.SELECTED DRAWING: Figure 1 |
