What's the most unexpected way you've seen industrial IoT data from PLCs reveal a production bottleneck that wasn't visible to human operators?

You know, the most surprising example I've come across was at a metal fabrication plant that had been struggling with throughput issues for months. The operators couldn't figure out why production was lagging - all the machines seemed to be running fine when they checked them individually. When they connected all their PLCs to an IoT platform and analyzed the data over time, they discovered something completely unexpected: the bottleneck wasn't any single machine, but rather the sequence in which products were being scheduled across four parallel production lines. The PLC data revealed that certain product combinations were creating subtle timing conflicts that human operators couldn't see in real-time. What made this particularly surprising was that the issue only became apparent when analyzing data across the entire production system over extended periods. Individual machine operators saw their stations running smoothly, but the aggregated PLC data showed how small delays were cascading through the system. The solution turned out to be optimizing batch sizes and production sequences - something that traditional spreadsheet modeling had completely missed. It's fascinating how IoT data can uncover these hidden patterns that are invisible to human observation alone!
