Hello, Here is a link to manual. LOGO! see chapter 2.4 From manual: -------------------------- 3. If there is a circuit program in LOGO! or on the card, LOGO! adopts the operational state it had prior to POWER-OFF. Versions without a display unit (LOGO!...o) automatically change from STOP to RUN (LED changes from red to green). |

Switch your LOGO! to RUN Then always after power up, your LOGO! goes automaticly to RUN |

Dear Vincent_Brussels, Normaly the LOGO must be on RUN mode after power on if it was on the RUN mode before power off. Otherwise if you power off the LOGO on STOP mode then it will be on STOP mode after power on. If this not help I suggest you to download another simple program to conclude if something is wrong on your program. Check also if you use initialization falg ( M8 ) on your program. Regards, |

Hello Wizard, Glad you came back to my problem, thanks. And remind me I could zip it The system is no longer with me, I cannot (easily) follow your suggestion, specially to remove the extra AM 2 AQ module to do the test. But I recall that up to a certain point, during development, the Logo! would start to run as it should have. Then, it would no more. But, you know, in the progress of the development, you tend to focus on the result you want to achieve and so, you simply run it from the PC to discover that it does not do what you want. And you go back to your PC to modify the PGM, without needing to check the auto run capability. All this to tell you that I can't know for sure at which stage of development the Logo! would no more sart in auto run. Plus, we had to wait for the AM 2 AQ module to be delivered. So, in the initial development, the part related to the analog outputs was not designed yet. Maybe the addition of the AQ module had some effect, but I doubt it. I recall that the auto run worked while the AQ module was not yet attached. All this to explain that the dissapearance of the auto run capability, during development, cannot be traced back. But, for sure, it did work at some time. That's why I'm convinced the source of the problem should lie in the PGM itself... If you could have a look on the PGM, that would really be nice. I'm not afraid to look stupid ! Many thanks, Vincent AttachmentJL-17-f.lsc.zip (268 Downloads) |
