Hello, There is no way to start a stopped CPU by it's own program, Program is not running and will never execute the instruction. In some cases you can prevent the CPU going to stop by loading the error OB's Which organization blocks do you need for error handling? Regards, Marcjan |
Problem solved? |

And if the CPU doesn't go to stop mode, can I restart it? |

Is there the possibility to clear the non retentive area/memory without restarting the CPU? Thank you all.

Hello , As prerequisite , the remote CPU should be in STOP mode and its key switch should be in "RUN" or "RUN_P".I suggest reading section "22.15 Initiating a Warm or Cold Restart on a Remote Device with SFB 19 "START" " of the following manual: http://support.automation.siemens.com/WW/view/en/44240604
For this case, you can use SFC20 or SFC21 to conditionally reset memory areas plus resetting timers and counters. Best regards Hamid Hosseini |
