METHOD AND APPARATUS OF CONFIGURING AN OPERATION MODE OF AN AUTOMATION DEVICE

摘要

A method (200) and an apparatus (600) of configuring an operation mode of an automation device are provided. The method (200) comprises detecting (201), within a control cycle, a first trigger event and a second trigger event of a supply voltage of the automation device. Each of the first trigger event and the second trigger event denotes switching of the supply voltage of the automation device between a first voltage (101) for a configuration mode and a second configuration for a control mode, the first trigger event has a voltage increasing direction or a voltage decreasing direction while the second trigger event has a voltage changing direction different from the first trigger event. The method further comprises configuring (202) the operation mode of the automation device based on detection results of the first trigger event and the second trigger event at the end of the control cycle. It could provide a solution of automatic operation mode configuration at a low cost. This solution could determine the operation mode efficiently and reliably, which could in turn improve the safety and reliability of the automation device greatly.
