PURPOSE:To check and recover easily a fault by collecting and storing information of a control device and state information of a device by an instruction of a higher rank device when time-out has been generated, so that they can be sent out to the higher rank device. CONSTITUTION:In a control device for collecting and storing information of a device (not shown in the figure) by an instruction from a higher rank device (not shown in the figure) and sending it out to the higher rank device, an operation instruction time-out signal of the higher rank device is started by sending it out to an information collecting and storing circuit 8 through AND circuits 6, 7 from a terminal B, when an operation executing circuit 5 is being operated, the information of the circuit 5 is collected and stored and the circuit 5 is reset through an FF9. Also, an information report instruction of the higher rank device is sent out to an information editing circuit 10 through an AND circuit 11 from a terminal C, and the contents of the circuit 8 are edited and sent out to the higher rank device from a terminal A through the circuit 5. In this way, a fault can be bracketed. |
