Abstract
A processing method for preventing electromagnetic induction when a main system and a standby system of a safety drive unit co-drive a relay. The method includes the following steps: periodically acquiring and detecting a drive command; detecting a port state of an output port of a safety drive unit when the drive command changes; performing a corresponding processing operation according to the port state of the output port; and repeating the foregoing steps.
