Analog Input AB NI8 Wont Enabled

Studio5000 has TASK, Programs, Routines in that order. You do not need JSR's if you create new TASK or Programs within a TASK, but if add routines then they must be called by a JSR. In the SLC there is only one Program, and ladder 2 is the main routine. All others must be called.
 
Yes, that is correct.

With RS Logix 500 (with reference to your SLC 500) LAD 2 is your main program file, which does not require a JSR. The following files, LAD 3 onwards are subroutine files, and require a JSR to be scanned. The JSR can be in the main program file, or any subroutine file which has been called.
