问： S7-300 中， 在 如何实现 S7-200 中 SM0.3 的功能?:即开机后进入 RUN 状态,ON 一个 扫 描周期,请各位赐教. 答：你必须在 OB100 中调用 SFB21 “RESUME”，原理及注意事项如下。 

If there is a rising edge at control input REQ, SFB 21 "RESUME" activates a hot restart on the remote device selected with the ID. The following conditions must be met if the remote device is a CPU: 1、The CPU must be in the STOP mode. 2、The key switch of the CPU must be set to "RUN" or "RUN-P." 3、When you created the configuration with STEP 7, you allowed for a manual hot restart. 4、There must be no condition preventing a hot restart.
