Real-Time PLC Failover Monitor
TL;DR
Agent-based PLC redundancy tool for factory engineers running paired control systems that auto-failover to backups within 1 second of primary failure and sends SMS/email alerts to on-call teams so they can reduce unplanned downtime by 90% and eliminate manual failover procedures
Target Audience
Industrial automation engineers and factory system managers
The Problem
Problem Context
Industrial systems rely on backup PLCs to prevent downtime. If the main PLC fails, the backup must take over instantly. But current setups lack reliable failure detection, leaving systems vulnerable to unplanned stops.
Pain Points
Users can’t trust their backups because signals don’t change during faults. Manual checks fail. If the system crashes, work halts, costing money and reputation. Fixing failures is stressful and time-consuming.
Impact
Downtime means lost revenue, missed deadlines, and stressed teams. A single failure can damage a company’s reputation. Factories can’t afford to wait for a solution—they need reliability now.
Urgency
Failures can happen anytime without warning. Users need a fix immediately to avoid costly disruptions. Delaying risks permanent damage to operations and customer trust.
Target Audience
Factory managers, industrial engineers, and automation technicians face this problem. Anyone running automated control systems needs reliable backup monitoring to prevent downtime.
Proposed AI Solution
Solution Approach
PLC Watchdog is a lightweight monitoring tool that watches two PLCs in real-time. If one fails, it triggers an instant alert and failover. No admin rights or complex setup—just install and forget.
Key Features
- Smart failover: If a PLC stops responding, the tool automatically switches to the backup.
- Real-time alerts: Notifications go to engineers’ phones/emails when issues arise.
- No false positives: Uses proprietary protocol checks to avoid misleading alerts.
User Experience
Users install the agent on both PLCs in minutes. The tool runs silently in the background, sending alerts only when needed. Engineers get instant notifications if a failure occurs, allowing quick action. No manual checks or guesswork—just reliable redundancy.
Differentiation
Unlike free tools or vendor support, PLC Watchdog is built specifically for PLC redundancy. It avoids false positives with protocol-level monitoring and works without admin rights. No other tool solves this exact problem for industrial users.
Scalability
Starts with two PLCs but scales to monitor entire factory networks. Additional seats can be added as the factory grows. Alerting and failover rules can be customized per system.
Expected Impact
Eliminates unplanned downtime, saving money and stress. Engineers sleep better knowing backups will work. Factories avoid reputation damage from failures. A small monthly fee is obvious compared to downtime costs.
