Allen‑Bradley PLC vs Schneider PLC: What the Datasheet Hides
Allen-Bradley vs Schneider PLC — You’re wiring a Modicon M241 into a retrofit line. The datasheet says five comms ports, 8 MB program memory, ~50 µs response. Looks strong. [...]

Allen-Bradley vs Omron PLC — You’re designing a system that needs to handle 12 axes of motion, a mix of safety zones, and a plant-floor Ethernet ring. [...]

Allen-Bradley vs Schneider PLC — The popular myth: Two micro PLCs, both rated “IEC 61131-3, similar I/O, a few hundred dollars” — so runtime and scan cycle are interchangeable. [...]
Continue Reading →Is runtime under real load really the bottleneck? The one variable that separates Allen-Bradley from Omron — and the myth that keeps engineers ordering the wrong PLC.
Allen-Bradley vs Omron PLC — Every plant-floor conversation about PLC runtime fixates on scan rate: "Omron runs a primary task at 2 ms, so it must be faster under load." Or "Allen-Bradley CompactLogix 5380 has a 1 Gbps EtherNet/IP… [...]

Allen-Bradley vs Siemens PLC — You’ve seen the datasheet race: 85 ns bit time on a Siemens S7‑1200, sub-millisecond scan claims on both sides. [...]
Continue Reading →“That PLC cycles fast—but can you keep that speed when the plant floor hits 50 °C and the panel is sealed?”
Allen-Bradley vs Mitsubishi PLC — You picked a PLC based on raw scan speed. The MELSEC iQ-F FX5U advertises a basic instruction time of ~34 ns, and that number catches your eye. [...]

Allen-Bradley vs Siemens PLC — It's the moment nobody budgets for: the line manager adds a dozen remote stations, and suddenly your 14-point CPU needs 28 digital inputs, two analog channels, and a safety overlay. [...]

Allen-Bradley vs Schneider PLC — If your plant runs on a diesel genset with ±15% voltage swing and 5–8% total harmonic distortion, the PLC that "works fine" on a stable utility grid can silently destroy your uptime budget. [...]
Continue Reading →Allen-Bradley CompactLogix 5380 vs Omron Sysmac NX1P2: TCO Ledger on a Noisy Generator Feed
Allen-Bradley vs Omron PLC — Nobody buys a PLC for its ability to run on a dirty generator feed. Yet that feed is exactly where the total cost of ownership diverges by a factor that no scan-cycle spec will show you. [...]
Continue Reading →Which PLC fails first in a tight-cooling shelter? Allen-Bradley vs Schneider — myth vs reality
Allen-Bradley vs Schneider PLC — You're looking at a PLC that must survive inside a sheet-metal enclosure with a single 60 CFM fan, summertime outdoor air intake, and a cooling capacity that was sized for a 400 W load, not the 600 W you've… [...]
