1. PID spotlight, part 2: Know these 13 terms, interactions
Learning proportional-integral-derivative (PID) controller tuning begins with the basics: Definition of terms, the PID equation (multiple forms) and seeing how each of the PID terms functions independently from each other and separated from a process.
2. New cost analysis: Open process automation saves 52% versus DCS
Part 1: While COPA projects 52% hardware and software savings from open process automation, O-PAS interoperable OPAF-aligned products are in field trials, devices are being tested, an adoption guide is underway and system integrators are preparing use of open controls, as explained at the 2024 ARC Leadership Forum. Lifecycle costs are measured at half of a distributed control system over 25 years.
