Three button exclusive latch?
Flex727 replied to RickL's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Yes, screen capture (alt-PrintScreen button), paste into Paint, crop, copy, paste into the forum. Quick and easy. From your post above, note that the Reset Numeric block is equivalent to Store 0 and takes up less space (see where I used it in the post above yours). -

Flex727 replied to RickL's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Why did you need additional set and resets? The button, when set as Toggle type, will look pressed when the bit is on and you can change the text and color as desired. Regarding the MIs, I can't imagine why you need to use logic function blocks with bits, but it's simple enough to do the following (do this with each button): -

To use buttons, as in your original post, is simple. Take your original logic, change the first contact to a positive transition, and change each button to be a Toggle button. It will look like this: -

Yes, I think that's what he meant. -
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. -
Refreshing screen
Flex727 replied to JC Castillo's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
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. -
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.

CANNOT LINEARIZE NEGATIVE NUMBERS IN URA-0800T
Flex727 replied to gongue's topic in UniLogic Software
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).

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.
