Case Study: Uncovering a Hidden PLC Failure

“After returning to work following the holiday shutdown, I found that three MicroLogix PLCs were in a faulted condition. Reviewing the building management history, there was not enough data to analyze to discover the cause. Thanks to RTA for providing a product that helped us resolve a critical issue. Your support and innovation are greatly appreciated. Keep up the great work.”
