I am an instrumentation student working on project that will hopefully use both a barcode scanner and a panelview screen. Currently the scanner is working and is connected to the PLC through the serial port(RS 232) on the processor. I still need to interface with the PanelView with the same PLC. Since the port is already being used with the scanner, is there any other way to connect the touch screen to the PLC? Thanks for the help.
