I agree with Leland “Tom” Taylor completely. My last project was a DDS (Distributed Control System) and we employed 19, μ-controllers (microcontrollers), that had digital and analog IO, math primitives, plenty of power and were interconnected by plain old Ethernet. Data collection and storage was a no-brainer. Software development could proceed a subsystem at a time. I would never do anything different, unless I were stuck in a 1970 time warp. We used 19” touch screen monitors, placed wherever they were needed. Histograms of process performance (stability, rate, energy usage, etc.) were available anywhere, including my living room sofa.
On a later project in MX I used a Siemens Simatic system. Is was much less flexible, cost at least four-times as much and had distributed I/O collectors but not distributed process management intelligence. Tons more wiring. No redundancy. Proprietary architecture. Mostly much slower but that’d not be as much an issue on a gasifier as it may be on motion control. And Siemens was years ahead of U.S offerings, who only until relatively only offered archaic Ladder Logic programming tools.

Sorry to hear that there are those out there who are still using the archaic plc architecture as it only makes for more work. Sincerely, Leland T.
