How to Reduce Downtime in Industrial Automation: 3 Data-Driven Strategies for PLC & DCS Operators

Industrial automation systems like PLCs and DCS are critical for smooth operations. Yet, unplanned downtime costs millions yearly. Here are 3 proven, data-driven strategies to minimize disruptions and maximize uptime.

1. Use Predictive Maintenance to Spot Issues Early

Reactive fixes are often costly. Instead, by leveraging sensor data and analytics, businesses can predict failures before they occur. For instance, trends in vibration or temperature can provide early warnings of motor wear. In this regard, GE’s Asset Performance Management tools excel, enabling data-driven decision-making. As a result, maintenance can be scheduled only when necessary, thereby avoiding unnecessary downtime and optimizing operational efficiency.

2. Optimize PLC/DCS Programming for Faster Troubleshooting

Undoubtedly, complex logic in control systems significantly slows diagnostics, leading to prolonged downtime and higher maintenance costs. To address this challenge, it’s essential to simplify PLC and automation code through standardized programming templates, well-structured logic, and detailed inline comments—all of which enhance readability and long-term system maintainability.

For instance, Rockwell Automation’s Studio 5000® provides powerful modular programming features, including function block diagrams (FBD), ladder logic standardization, and Add-On Instructions (AOIs), enabling engineers to develop cleaner, more reusable code. Moreover, by adopting these best practices, teams can drastically reduce debugging time and improve cross-team collaboration.

Beyond streamlined programming, another critical improvement is the implementation of intelligent alarm management systems. Specifically, systems compliant with ISA-18.2 standards help filter, prioritize, and suppress non-critical alerts, ensuring operators focus solely on high-impact faults. As a result, this minimizes alarm fatigue, accelerates root cause analysis, and reduces reactive troubleshooting efforts.

In summary, by first simplifying code architecture and then integrating smart alarm handling, industrial operations can achieve faster diagnostics, lower MTTR (Mean Time to Repair), and more efficient maintenance workflows. Ultimately, this proactive approach aligns with modern Industry 4.0 principles, driving operational excellence and reducing unplanned downtime.

3. Leverage Real-Time Data for Smarter Decisions

Live dashboards show system health instantly. Bentley Nevada’s System 1 software, for instance, tracks machinery metrics in real time. Pair this with historical data to spot patterns. Quick action prevents small glitches from becoming major halts.

Conclusion

Reducing downtime isn’t luck—it’s strategy. Predictive maintenance, clean programming, and real-time data cut failures sharply. Start small, focus on high-impact areas, and scale up. Your bottom line will thank you.
