In practical application, the control device actively acquires and reads an execution response instruction of the controlled device.
S103: and judging whether the fault state of the controlled equipment can be read in n execution cycles. If yes, go to step S104.
Specifically, the n execution cycles may include: and n control devices are used for executing the control command period after sending the control command.
For example, after the control device reads the execution response instruction of the controlled device, the fault state of the controlled device is read in n execution cycles after the current time of reading the execution response instruction.
It is emphasized that n may be a positive integer, e.g., 1, 2, 3, etc.; n can also be adjusted to decimal, such as 5.2, 8.7, 10.8, etc., according to actual requirements.

As shown in fig. 2, when the execution result is abnormal, or the fault state of the controlled device can be read within n execution cycles after the control device sends the control instruction, or when the received information reported by the controlled device is the information of the fault of the controlled device, the fault processing step is entered, when the fault is a fault that can be cleared, a clear instruction is sent to clear the fault, and then the control instruction is sent again, and at the same time, the fault state of the controlled device is read, and the number of times of resending the control instruction is accumulated, and if m is taken as the difference between the accumulated number of resending the control instruction and the preset threshold, the value of m is reduced once every time the number of resending the control instruction is accumulated. When m is zero, the fault information and the fault code corresponding to the control instruction may be uploaded to the monitoring device that monitors the entire system.
By applying the embodiment of the invention, if the fault can be cleared during fault processing, the control instruction is sent again after the fault is cleared, so that the normal operation of the system can be ensured as much as possible.
