sampleAnswers

:"In my last position, we faced an issue with a PLC continually crashing during production. I conducted a thorough analysis of the error logs, which indicated a memory overflow. I then rewrote the logic to optimize memory usage and implemented data logging to monitor usage. After deploying this solution, we maintained a stable system and increased production efficiency by 15%."

"Another challenge I faced involved an unexpected failure in a control loop that caused a bottleneck in the process. I reviewed the PID settings and realized the tuning was off. I recalibrated the PID controller and tested different parameters, which resolved the issue and restored normal operation, reducing downtime by 20%."
