The invention discloses a sequential secondary device control method with association of the running state of a primary device. The method comprises: a corresponding operation task in each sequentialcontrol operation application scenario as well as a sequential control operation corresponding to the operation task is preset; a sequential control operation application scenario is selected and an operation task in the sequential control operation application scenario and a sequential control operation corresponding to the operation task are performed automatically; after sequential control operation ending, actual investment and exit states of one group of soft pressing plates corresponding to a protection device are obtained automatically; and the actual investment and exit states are compared with the investment and exit states of the group of soft pressing plates in a preset target investment and exit state of the protection device. According to the invention, the corresponding sequential control operation is performed automatically based on the operation task and thus automatic investment and exit of the protection device and automatic execution of the safety measures are completed; and the operation and maintenance personnel or the maintenance personnel does not need to select the specific process of the sequential control operation.
