In S-115u cpu943b plc i removed eprom & battery then i done the overall reset , after overall reset , i put the switch in run mode
(only with power supply & cpu i am not inserted any i/o modules) i observed the stop led continously glowing.in step5 ISATCK observed(stozus,stoanz,keinas are red marked).is it possible without any modules & without userprogram the cpu will go run mode or not.
