I have a Micrologix (1500 LRP Series C ) controller with three Input cards and two out put cards in the expansion slots ( 1. 1769-IQ16, 2. 1769-IQ16, 3. 1769-OA16, 4. 1769-OA16, 5. 1769-OA16). I downloaded my program but when I try to go to run mode the processor faults out. ( S:1/13 = 1 and S:6 = 21h) I have looked in the fault description but can not find a fault 21. Thanks for the help you all have been giving me you have helped a lot
