 A [large US manufacturing company](/customer-stories/manufacturing-digital-transformation/) with over 10,000 employees uses FlowFuse to manage thousands of Node-RED instances deployed across global facilities. These instances collect data from sensors, PLCs, and cameras on production lines, enabling them to transition from paper-based operations to real-time data visibility. A team of five developers—former manufacturing engineers, not software specialists—built hundreds of applications using Node-RED's visual programming. FlowFuse now manages deployment to thousands of remote devices and maintains multiple versions across all instances, solving what had become an unmanageable tracking challenge as they scaled.

 What keeps a Modbus installation stable for years is mostly mundane: a poll list reviewed quarterly against the actual field, scan rates tiered with the reasoning written down, timeouts calculated from measured device response times rather than defaults, and per-device success rates visible on a dashboard that someone checks regularly enough to catch drift before it becomes failure. None of it is sophisticated. All of it requires treating the Modbus layer as something that needs ongoing maintenance, not a configuration artifact from the last integration project.
 
 If you've worked through both parts and the installation is still misbehaving, you're likely past what configuration review can resolve. Power quality on the RS-485 segment, a device firmware bug producing malformed responses on specific register ranges, or a network infrastructure change that introduced unexpected latency: these are real causes that look like everything else until you rule everything else out. A [protocol capture](https://en.wikipedia.org/wiki/Packet_analyzer) on the wire during an active failure event will tell you more in twenty minutes than another hour of configuration review.

It just requires treating these as decisions rather than defaults.
 
 If you've made these changes and your installation is still misbehaving, the problem is in the operational layer: how your polling architecture handles the network and devices once they're running.
