Hi all,

I need to display an EAN128 barcode on a 7" basic panel. The string is in a DB and is 8 characters long (e.g. "40012345"). I can't find anywhere a tip on how to do this.

Anyone an idea?

Thanks.

I cannot think of the elegant way I would want to do it... By loading a EAN128 FONT into an HMI, and then use that font to display bar-code data.

However, you can simulate this behavior using IMAGES taken from screen grabs from your PC after installing an EAN128 barcode font.

Then name each of the images that represent parts of the EAN128 bar code and then display the images side by side with no space and fixed width.

This web page ( http://www.keyence.com/ss/products/auto_id/barcode_lecture/basic/code128/ )seems to contradict your post's example barcode data.  Please look at it and post a reply.

I suggest a more advanced HMI so you can load a custom font to handle the bar code so you can just point the bar code at your string tag within the db, and it then displays the correct bar code for that string.

I have loaded a code128 font into the HMI. Do you know if it is just enough to calculate the string, and then just put it up on the screen in code128-font?

Simulate it!  Then use a smart phone to scan the barcode.  If it succeeds at scanning and displays the value in your string, you are smiling.  Now create your test cases for things that might cause problems, like leading 0's, or if you accidentally only have 7 characters.  Hopefully your program detects the length of the string is too short during data entry and raise an alert / alarm / warning for the operator / user.

Didn't work .

I mis some control characters I guess. Have to do some more research. Or does anyone did it already and is willing to help?

Thanks anyway.

Dear taco,

1. Install your font on your Engineering Station.
2. Open your project and go through the "Runtime Settings" of your basic Panel.
3. Open "Language & font" Settings.
4. Select your font under configured font 1 for each language
5. Open the Picture with your I/O field.
6. Bind your string tag through the I/O field.
7. Go through the "Properties" of the I/O field
8. Open the "Text Format" settings und select the Barcode font.
9. Download the project through your Panel. The Barcode font will automaticlly transfered to your panel

Do you know the "Toolbox for HMI Projects"? The you can find a detailed describiton
