Why is the AQ indicator always on when the PLC program hasn’t been downloaded yet? Is it abnormal or not?

It's normal that  the AQ still has output when there is no program inside the PLC. For example: The PLC analog will output according to the minimum value of the range which you configure when there is no program, for example (the output types: -10V~+10V, then it will output -10V voltage).
