Hello All I need some help with Logo! analog value retention after a power failure / Reset. The parameters are set on the customized page and operate well until a power outage when they reset to 0 on reboot. I have tried some of the solutions given (Mathematic Instruction, Max/Min. etc) but don't seem to have any success. Thank you AttachmentRetTest1.zip (744 Downloads) |

In attachment a solution. Take a look in the LSC program to the Parameter-VM-Mapping. AttachmentRetTestA.zip (836 Downloads) |

Hello ixo65 Thank you for the info/solution. I added the top Analog Marker to get the "Rainbow" to display correctly with my 0 to 5v dc Input. I still can't seem to get the solution to work. When I try to enter 80 in the upper parameter the lower immediately shows 20500. and when I type 20 in the lower parameter to upper goes back to 0? I am obviously getting something very wrong.

Hi Thank you for your quick reply and solution. I tried to change the solution you send because it didn't seem to retain its values after I had dropped the power to the logo. I download the solution for both LWE and LSC. I have attached a video so you can see how it performs. Not sure what I did wrong? AttachmentLogo1-1_1.mov (774 Downloads) |

I don't know what's happening to you. But it doesn't happen to me. I also created a screen video. And there you can see that after a power failure of the LOGO!, the target values that were transferred from the extended web server are retained. You can see that I switched off the voltage for the LOGO! during the online test by the LSC message "Transmission failed". AttachmentOnline-Test.zip (763 Downloads) |

Thank you. Your solution is so much better than the one I had where all my analog values would go to 0 after a power failure. At the moment my values go back to a preset default value i.e. the value that is in my LWE when I download the program to Logo. I have checked my settings but can't seem to find my problem to get it to operate like yours? Had to split the video into two see next mail for part 2 Kind regards Roy AttachmentLogo1_2_1of2.zip (627 Downloads) |
