I know it sounds a little crazy, but you _can_ build your own keyboard and part # entry screen.

https://support.industry.siemens.com/cs/document/51967032 extended for A-Z (a-z).

The better option might be to remove invalid characters with a popup saying "<original> invalid".. is "<non a-z|0-9 removed>" correct? Yes/No/Cancel.

For the project I'm doing, the operator has to enter a string of 7 alphanumeric characters. This represents the unique part number.

For now, the part number is not cross-checked with a "master list" of part numbers.

The part number is to be accepted, as long as it's alphanumeric. (i.e. any of 0-9, A-Z and a-z).

e.g.

48MS124 is valid

48M@124 is not valid.

Anyone got any ideas of how to program this in TIA/WinCC?

Is there a way of invoking a keypad on the touchscreen such that it only has alphanumeric characters? i.e. no maths functions, no minus sign etc.

Hope that makes sense. Happy to expand, if not clear.

Thanks
