Logixpro Dual Compressor Exercise 2 Review

In the LogixPro simulation, you had ladder logic timers: T4:0 for the “minimum run time” and T4:1 for the “anti-cycle delay.” Maria had no time to program. She had to become the PLC.

In LogixPro’s “Dual Compressor Exercise 2,” the goal was simple: maintain 90–100 PSI with two compressors, handle duty cycling, and prevent both from running simultaneously for too long to avoid overload. The twist? A random “fault” could disable one compressor, forcing the other to handle the load within strict time limits. logixpro dual compressor exercise 2

Atlas groaned, then spun. The unloader, freed by the pressure relief, clicked open. The compressor started unloaded. Pressure had fallen to 82 PSI—two pounds above disaster. In the LogixPro simulation, you had ladder logic
