Posted 23 Oct 2015 Alright, so I'm a bit confused. I have been under the impression that once the key switch is placed in Program, all ladder execution ceases and outputs are frozen (selectable under the I/O Module Configuration). I was going through a program for a L61 that has roughly a dozen periodic tasks with ladder routines under them. When the controller is placed in Program there are at least a couple routines that run, as a GSV for Controller Status is performed and then in another routine an alarm tag bit is set to notify users the key switch is not in run. I've looked under Controller Properties and the properties for individual tasks but don't see anything involving a 'run when in Program mode' selection. What am I missing here?
