[Trigger valve when count reaches 30]

Sorry, I lost track of which forum I was in. I don't think U90 has the Reset Numeric function either.

Increment just means "add 1".

[Value Fluctuation]

How many decimal points of precision on your clamp? Also, are you sure the clamp doesn't have some built-in filtering?

The 60 point fluctuation is only about 1.5% on a 12-bit input.

[Toggle COIL not constant]

You can use both a positive transition contact and a negative transition contact to activate your toggle bit. However, it sounds like you don't need the toggle bit at all. Just use the positive and negative transitions of your input to log your time stamps.

[Project has too many fonts, is there a good way to rectify this?]

Strange. The project I'm working on right now has 24 fonts installed, of which 17 are in use. It compiles with zero errors. What PLC and VisiLogic version are you using?

[Changing number of Decimals in Numeric Controls]

You can't change the number of implied decimals on a numeric input at run time. Just set the numeric input for the maximum number of decimals and the user can input only the needed decimals. If the input is set for 2 implied decimals and the user only inputs 12.2, the correct value will go into the PLC (in this case 1220). As always, you need to do the math to handle the implied decimals.

[Toggle COIL not constant]

Are you using a positive transition contact for your input?

[Changing number of Decimals in Numeric Controls]

Can you clarify exactly what you're trying to do?

[Trigger valve when count reaches 30]

You need an increment function in addition to the compare function - something like this:

You will also need some logic to turn off O3 at some point.

Good to hear! Thanks for the follow-up.

[expansion error]

Check your power supply to the EX-A1 module.

[Hebrew and English]

Add a Hebrew font to the project and select that font in the String Library?

[expansion error]

How did you check all the connections? Visual inspection is often not enough. Try wiggling each of the components to see if you can induce a fail.

[Trigger valve when count reaches 30]

Use the input to increment a counter with a preset of 30. Use the counter to trigger the output. Search on Counters in the Help file to understand how to use them.

Alternatively, use the input to increment an MI. When the MI = 30, trigger the output.

[expansion error]

The first thing I would do is check or replace the cable between the PLC and expansion adapter. Then check the connections between the EX and IO modules.

[CNC Router machine]

Do you have a specific question or are you looking to contract some programming help? If the latter, you may want to post to the forum on this board called "Projects Seeking Programmers".

[conical fermenter tankshape]

Great point, @Saragani!

[conical fermenter tankshape]

1) Create your tank in your preferred image editing software (I use Paint because I am a simple guy). I also use .bmp for the format (though I will use .png and a different image editing software if I want a transparent background). Or obtain or purchase an image you like from another source and download it to your hard drive.

2) In UniLogic, select the Image Element type you want to use from the HMI menu.

3) Click on Image Source and navigate to the file on your hard drive and select.

Which part are you having difficulty with?

[Jazz and pt 100]

The PT1000 value has an implied decimal point. Your set value doesn't. In order to do a compare you need both values to have the same number of implied decimals. The easiest thing to do is to use a set point that also has one implied decimal, but is you want to enter whole numbers only then you need to multiply the entered set value by 10 (and store it in a separate place) before you do the compare.

[Timers for every day]

There are Direct and Indirect Clock Functions available. Take a look at those and the associated Help entries under Clock Functions. The Help file is well detailed.

[Confused about setting up IP information for PLC email system.]

Good luck! PLCs are not really designed to send emails so it can sometimes be a struggle.

[VisiLogic 9.8.64 update]

Can I just say that the ability to zoom V700 and larger HMIs in 9.8.64 is the greatest thing ever? I'm getting more and more work with V700s and V1210s and I can now use my large high-resolution monitor to its fullest extent and place HMI elements with precision without fussing around. Thank you for that update!

[Confused about setting up IP information for PLC email system.]

Yes, you need to have the user input the information for their server, IP address, etc. Joe Tauser's program that I linked to you earlier shows you what needs to be done.

[Set up a Master "Master"....]

Yes, MODBUS TCP. Under the scheme I mentioned, the V1210 would be Master to Samba1 Slave, Samba1 would be Master to Samba2 Slave, Samba2 would be Master to Samba3, etc. The PLCs can easily act as both Master and Slave simultaneously on two different sockets.

During a recent Unilogics software upgrade my PNG files that I had created were deleted from the Windows 7 Unilogics folders.

This is not a Unitronics problem. Nearly every program installation process will do the same thing. Microsoft sets up the "My Documents" folder for a reason. Never ever add user files to system folders.
