unmatching between hardware and online simulation(AC 500)
I write a program with any erroro and warning in compilation. also i downoaded it to PLC correctly.my problem is when simulation of program(Online), my DO in software according to my programming logic is correctly ON or OF, But with my DO module(hardware) is not match. it means LEDs of output that must be true/false according to my online simulation, are not true/false.
may be my hardware is damaged or not?
whats the problem?
cpu is AC500-PM564 AND DO is DO562
as par the previous answer with the same question, if you are sure that you have exactly the SAME configuration in program and in hardware, the problem could be inside the program.
Try to post the program and the screen shot of configuration.
