i using HKY(212) reads up to 8 digits of hexadecimal data from a hexadecimal keypad and stores the data in D00000 and D00001. The hexadecimal keypad is connected through CIO 0100 (allocated to a CS1W-ID211 16-point DC Input Unit) and CIO 0200 (allocated to a CS1W-OD211 16-point Transistor Output Unit). D32000 is used as the system word. a wiring diagram and program i put in attachment. I already try this program and it not work. I using CJ1M PLC to try it. thanx Husanto
