Metal Head part 2 Posts: 14 Rating: (0)	Hello, I am creating a project with WinCC flex that is requiring to display a barcode that includes intergers and letters on a TP177B. The DB on PLC has this information set up with CHAR bytes in an array of ten. My question. I currently have created a CHAR format tag in WinCC for each CHAR byte on the PLC I thought using a IO field would be the way to go but there is no CHAR type to chose in the display format info. I have looked thru the options with simple objects and can't seem to find anything realated to CHAR display. this is a simple project. I would think that there would be an option to display a single CHAR. I tried testing the IO field option but when i tried testing in simulation, would return a the famous '#' when trying to input. any suggestions? Is there an easier way to display the full barcode array with one window versus creating a object for each charactor?

Deine the length of the string. Try thishopeit willwork in your favour. Feel free to revert back in case of any query.
