Technical Requirements (phase 1)
Technical Specification – Design Phases of the Control System This is the first article in this series where we try to describe the different design phases of a control system. In PLC-based systems the design engineer must analyze all the technical requirements and make the design that meets the specifications […]
PLC vs DCS
PLC vs DCS – What solution to choose? When we want to integrate several software applications, use advanced control algorithms and have future expansion plans, the PLC / SCADA solution may not be adequate. Currently the differences between both solutions have decreased, but they are still important, especially in systems […]
