    While this will work when going from a Samba to a V350, it won't always work (for instance, when going from a color to a monochrome HMI). In that case one would need to export each subroutine and import each one into a new project with the correct PLC model selected.

    I've never seen the first one - perhaps a Watchdog Timer error? The second one is usually from a bad or disconnected cable that connects the PLC to the I/O modules.

    Sure, just change the PLC in the HW Configuration from Samba to V350 and select the appropriate I/O module. It will throw up a warning about deleting I/O, but ignore that.

    Okay, I'm stealing this.

    I rarely use the comms dropdown box, but I just checked and I see the same problem as Ausman. I am also still seeing the Modem box pop up randomly when I try to connect to the PLC over serial connection. When that happens the connection is dropped and cannot be restarted. FYI, this is using VisiLogic 9.8.31 and Windows 7 - 64-bit.

    Am I missing something, or is everything backwards in the linearization function block? Shouldn't it be: X1 - 3277 Y1 - 0 X2 - 16383 Y2 - 100 Maybe it doesn't matter, but seems very counterintuitive.

    Do not be sorry. That's what we're here for.

    Just create logic to do the same thing.

    Be sure to set the Powerup value to RESET for that bit. I've been burned by that and have learned my lesson.

    Which of the 3 types of timers are you using? Just working from memory, a new timer preset will not take effect until a timer coil is called in the ladder, or if a timer reset coil is activated. Are you certain the timer coil is actually being activated (i.e. is the subroutine being called, etc)?

    You may be able to buy an off-the-shelf programmable thermostat that will meet your needs, but if you want a PLC to do this job, you will not find an easier or more straightforward programming environment than Unitronics VisiLogic. Best of luck to you.

    andrew39, have you uploaded files on this forum previously? If so, the upload limit is cumulative. Go and delete the files you previously uploaded and your upload limit will increase.

    This is very simple. You need to use the function on the menu under Utils/Clock/Direct Clock Functions/Day of the Week in series with the function Time (found in the same place) to store 20 in an MI for the thermostat setting for Monday 10:00 to 12:00. Do the same for each separate setting you desire. You can use indirect values anywhere you want to have an operator input, whether for the time settings or the thermostat settings.

    I'm working from memory also, but as I recall this pop-up box is making a RECOMMENDATION. It does not actually do anything other than download your program update (and perhaps reset, not initialize, the PLC). It is up to you to preform the initialize (or not) which would erase your registers.

    I've never known an Ethernet connection to fail if the following are true: 1) Confirm the ethernet IP address is correct (check in INFO Mode) 2) Confirm the PLC Name is correct (check in INFO Mode) 3) Make sure your PC is on the same subnet as the PLC (first 3 octets are the same) I'm told modern ethernet adapters will auto-adjust, but I always use a crossover cable or hub just to make sure.

    Make certain you are selecting the correct COM port in the VisiLogic software. Also, if the PLC is new enough to have a USB port, use that instead of the RS232 cable.

    Here is how I ended up solving it. This application changes the display brightness by touching and sliding the Bar Graph left or right. The ladder logic would need to be adjusted for the actual coordinates of the slider bar. Note that I check to make sure the correct screen is being displayed and that the PLC is not in INFO Mode.

    There are two example programs included with your VisiLogic installation that shows how to use the Struct function. Look under "Vectors" - one is in the "Projects" folder and one is in the "Functions" folder.

    On the left side, right in the middle of the Numeric Variable setup is a drop-down called "Leading:". There you'll find 3 selections: Leading zeroes. leading spaces, no leading. Try changing to "No Leading" and "Text Alignment" (far right, near the bottom) to "Center Left".

    It's very important to provide some basic information in order to receive advice that has a real chance of solving your problem: -Which version of VisiLogic? -What operating system? -Does it also do this when you approach it from a different direction (such as right click on an operand in the ladder and select Find...)? -Has it being doing this all along, or is it a new development? That said, did you install VisiLogic as an Administrator? Are you starting VisiLogic from a shortcut that runs the application as an administrator?

    Did you try hovering your mouse cursor over the A,B,C,D fixed descriptors?
  23. Flex727
    You might want to ask this in the UniLogic forum. With Vision products you can use SB300. My recollection is that this is not available with UniStream, unless it has been very recently added.
