JotaPey Posted November 27, 2018 Report Share Posted November 27, 2018 I am working on a project that requires an operator to enter a field (on the HMI Screen) by scanning a bar code. I want to be able to confirm that the scanned field has a specific number of characters. The field is linked to a tag that is an ASCII string. It will be an alphanumeric string 25 characters long, and I want to confirm that the scan in fact inputs all 25 characters. Any thoughts on how to do that would be much appreciated!
