Logixpro Dual Compressor Exercise 2 ✦ Updated & Authentic

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.

“You just passed Exercise 2 with a gold star,” said the plant manager, handing her a bottle of water. logixpro dual compressor exercise 2

She hit start again.

Maria’s mind flashed to the exercise rubric: “When a compressor faults, the alternate must take over within 2 seconds. Pressure must not fall below 80 PSI.” In the LogixPro simulation, you had ladder logic

For six years, the system had run on a simple lead-lag routine: Titan ran all day, Atlas kicked in only when the pressure sagged below 95 PSI. It was dumb, but it worked. Until the heatwave. She hit start again

When the maintenance crew finally replaced Titan’s fan at 4:00 PM, Maria collapsed into a rolling chair. On the HMI, the pressure trend showed a near-perfect line at 88 PSI, with only one brief dip to 81.5 PSI.
