    I watched the attempted moon landing today with great anticipation. Sadly, there was a failure just seconds before the landing which prevented the mission from being a total success, however, I would like to congratulate the Israel Space Agency, Israel, and all the Israeli people for what they did accomplish. This was a private initiative that attempted to do something that only 3 other nations have accomplished in the history of man (and something that none of them are still able to accomplish). What they did successfully accomplish was to place a spacecraft into a stable orbit around the moon, which also has only been performed by three other nations. This was an inspiration to us all and I am certain the next attempt will be 100% successful.

    Seems like there should be an easy answer to this, but I don't see it. I'd like to flash text on a web page (i.e. flashing warning message). Using Frequency.Frequency 1 (s) to turn a visibility bit off & on doesn't work, presumably because the web page is not refreshing often enough. I know there are HTML tags to allow text to flash, but how to make UniLogic do that?

    Did you perform a screen calibration?

    As Joe said, this isn't Unitronics software. While it may be useful as a learning tool, I would never use it in a production environment. The PLCs themselves are relatively inexpensive - buy one to use for development if you are doing serious programming. It is the only way to ensure you are getting the results that will work in a actual production environment. I say this as an independent contractor - I have no relationship with Unitronics except for the assistance I provide on this user forum.

    Then you just need to select RESET as the Power-up parameter NONE is the default selection): All of the PLC memory is retained through power cycle by default (if the battery is good). This includes the state of Outputs. This isn't an issue with Direct Coils, but if you use Set & Reset Coils, then you need to pay attention to this detail. Your Reset Coil has the logic property of Reset, but when in online mode, the red is just indicating the state of the bit, on or off. Any type of coil will indicate the state in the same way. It is different when the bit is a contact. Contacts will show power flow and thus an inverted contact will be red when the bit is off.

    Why not log your data directly to the SD card as a .csv file?

    Just a few observations: 1) Do not place multiple logic networks in a single ladder rung. 2) What did you use to start Motor 2 while Motor 1 was running? HMI pushbutton, or what? I agree that if MB 3 is on, then turning on MB 6 should not turn on MB 7. 3) You misunderstand what the red lines mean. If a bit is red, then that means it is on (or True). The type of coil is irrelevant to the fact that it is on.

    I learn something new every day I'm on this forum. You can always use an intermediary: MB 5 would then be used on your reset input. The PLC isn't going to care about the extra line of code.

    It's been way too long since I did any Siemens S7, so someone might want to check me on this, but I think it would look like this: MB 0 would be the equivalent of Q 4.0 in your example.

    Moved to the correct forum. Search Operands in the VisiLogic Help file: Also, there are many example programs that came with your VisiLogic installation. Take a look at some. Unitronics has a YouTube channel where they show the basics. Take a look there as well.

    @Heitor, I moved this to a new topic since it did not belong in the thread you replied to. The answer to your question is that you can't change which screen is the Start-Up screen. You can create a new HMI screen and copy the elements from your Start-up screen to it. Then you can edit the actual Start-Up Display to be what you want. It is recommended that you do NOT change the name of the Start-Up Display, as that does not change the Start-Up property. But if you do, you can always tell which is the actual Start-Up Display by looking for the orange highlight.

    There is no internal PLC command of that nature that I'm aware of. You might want to contact Unitronics Support and see if they can help.
  13. Flex727
    Why did you feel that was necessary? All you're deleting is the descriptor text that the PLC never sees anyway. If you have a bunch of operands that are no longer being used and you find the descriptor text annoying, you can go to View / Operands Not Referenced in Project. That will generate a list that you can delete from.
  14. Flex727
    Sorry, I have no idea what any of this means.
  15. Flex727
    No, you only need to delete calls for the specific subroutine or display you want to delete. As CAM said, they are easy to find.
  16. Flex727
    Your reply is unclear. Try deleting any entry into the Disable View function, download the updated program into your PLC, and then tell us what happens.
  17. Flex727
    Have you checked to see if MB 83 is on when the buttons aren't working?
  18. Flex727
    You must delete the reference to the subroutine or display first. For instance, if the subroutine is called in ladder that subroutine call must be deleted first before you can delete the subroutine. Same goes with HMI displays.
  19. Flex727
    You need to show the variable box opened so we can see the details.
  20. Flex727
    Without more information it's going to be difficult to be of any help. Post a screenshot of the open HMI Variable box.
  21. Flex727
    There are Clock functions in the Utils drop-down menu. They will do what you are looking for. There is also a lot of good information in the Help file under Clock Functions.
  22. Flex727
    Can you post your program?
  23. Flex727
    Nice work, Joe.
  24. Flex727
    Because it can't be done without the Set SD Password FB pre-existing in the program.
  25. Flex727
    If you have a Set SD Password FB in the program.
