Frankly, I'm at a loss as to what you are trying to do. You don't need AND or OR functions with bits. Simply do this:

I'm trying to figure out if this is something new or just something I failed to notice in the past. I am using VisiLogic 9.8.96 on a V700. When I have a List of Images element on the HMI screen and the image changes, the entire screen refreshes, not just the one element. This does not happen with a Binary Image element. This is very noticeable because it is a complex screen and it takes about a full second to refresh the screen - it's very visible and annoying.

1) Download 9.4.0. 2) Install 9.4.0 by right-clicking the executable and selecting "Run as administrator". 3) After installation, run VisiLogic "as administrator" (either right-click and selecting "Run as Administrator", as above, or set up the shortcut under the compatibility tab to always run as administrator). 4) Open your original project file in VisiLogic. 5) Make your modifications and save the file under a different name so you don't lose your original file. 6) Install the USB driver for your PC (done in VisiLogic in the Connection menu). 7) Connect mini-USB cable to the PLC. 8 ) Confirm communications in the connection menu. 9) Download program to the PLC. 10) Check your changes work as desired. If so, you can then download & burn, if so desired. You're done.

Use a Positive Transition contact instead of Direct contact for MB 11, 12, & 13.

Try using the Store and Subtract functions. All kidding aside, is there something you're trying to do that I'm missing?

Haha! Wow that got by me.

Which PLC model? On most of the Enhanced Vision models you can find the screen refresh FB here: Then just trigger that with a timer or any other action you wish.

By the way, I have the 9.4.0 installation file, but it's 145MB and I don't have any way to get it to you. If you have some online storage I can upload to I can do that, but try support first.

The database number is associated with the VisiLogic version number. You don't need anything else except version 9.4.0. You may have to ask for that from Unitronics support.

I see the problem now. You say above the project was created with version 7.0.1, but the important point is which version was it last saved with. I just opened it and I see that it was saved with version 9.4.0. That is the version you need. Get that version and all your problems go away. I use Version Swapper every day. It works perfectly. I have at least a dozen different VisiLogic installations on my PC that I swap between. The function of Version Swapper is to provide the programmer the means to edit projects without having to upgrade the PLC firmware (precisely as you're attempting to do). However, it may be a bit of a pain for a one-time use. Just uninstall whatever version you have, obtain 9.4.0, and install it. Make your changes and download. You need 9.4.0 then you will not need to fool with the firmware.

If you already have a UINT16 in E or F, it may not let you use INT16 in C. Make sure you're entering INT16 in C, E, & F.

When working with integers you can increase precision by multiplying by the factor of 10 to give you your desired precision. For example, if you want the linearization result to be displayed to one decimal precision, you can linearize from 0-100 instead of 0-10 (if the range was 3-17 you would linearize from 30-170). Then you just set up your bar graph from 0-100 and you can display on the HMI showing the result with a decimal place (the HMI element allows for that).

Here is the way I would do it:

I haven't run across this particular error, and this is probably not a solution (but who knows?), however, I strongly recommend upgrading to 9.8.96. Files saved with 9.8.95 open seamlessly with 9.8.96 and 9.8.96 files do not require any firmware upgrade on the PLC that is running with 9.8.95.

You can save operand values in VisiLogic, and a Clone file does save the program with operand values included.

This is always wise, but FYI for OP - standard download should not disturb operand values.

I've worked with dozens of V1210s over the years and had no problems, but recently I've gotten at least two V1210s that have touchscreens that require much more touch force than normal. One of them is quite excessive and in fact I thought the touch screen was inoperative as first. Is there something that can be adjusted for touch sensitivity on these PLCs?

Yes, but you will have to update the firmware on the PLC first. It's not difficult. Registration is for the PC. Burn Upload Project allows anyone to upload the VLP file from the PLC. Most do not do that to protect intellectual property rights. It's almost impossible to brick these PLCs. That said, here is what I recommend: Download VisiLogic version 7.0.1 from the Unitronics website, or request it from Unitronics Support. Uninstall your version and install that (alternatively, install Version Swapper and download the Swapper version from the website and use 7.0.1 by swapping to it - that will allow you to use 7.0.1 without uninstalling 9.8.65. Then make your updates and download the update to your PLC. It's not likely you will have a problem by using 9.8.95 and upgrading the firmware, but there is always a risk of some incompatibility when undertaking that.

Sadly, not very readable. Try this:

I'm pretty proud of this one. This routine will run one of 20 recipes, each recipe can have up to 20 steps, and each step has 4 elements. The entire routine requires 13 ladder rungs - the operator merely selects the recipe and presses the run button. It may not look like it, but it's actually a State Machine.

Yes, I really wanted the guy to ask more ladder logic questions. Yes, ChatGPT is actually really amazing, but real AI it's not. I'm looking forward to future iterations.

Thanks for reporting back.
