Good Afternoon,

Wondering if anyone can point me to the lowest cost software (bonus points if free, a long shot, I know) for being able to read the logic execution of a PLC. We have a large semi automated process that has a custom controls cabinet utilizing AB - Rockwell PLCs to control numerous motors, solenoids, pumps etc. When we have an issue currently we are at the mercy of the customer service of the controls integrator, they are always helpful but it takes a long time. My goal is to be able to see the logic executing so that I can pinpoint where it hangs up. This is after checking all of our usual electro-mechanical failure points, stuck solenoids, blown fuses, etc. Any insight would be greatly appreciated. 

Thanks all, for your time,

-Miguel
