# Example: Use a string display

Create a string display and assign a string tag to the Value connection. The application reads the Value connection and updates the string display.

For example, a process carries a variety of parts past a fixed barcode reader on the shop floor. The barcode reader passes its data to a string tag in the PLC. The string display monitors the string tag, and shows the string associated with the code currently being read by the barcode reader, that is, the name or identification number of the part passing the reader.
