Phase 4: CPU selection and Control System Architecture In this article we discuss how to select the CPU and describe the main options for the Control System Architecture (index of design phases). 4-CPU selection and design of Control System Architecture The selection of CPU and PLC / PAC model […]
Functional Distribution (phase 3)
Phase 3: Grouping and segmentation of I/Os and Racks (functional distribution) In this article we discuss the importance of the functional distribution of I/Os, especially in medium size and large control systems (index of design phases). 3-Grouping and segmentation of signals and racks – Functional distribution The way we […]
Selection of I/O modules (phase 2A)
Phase 2: Selection of I/O modules (part A) In this article we discuss the selection of Input / Output Modules (part A) (index of design phases) 2A-Hardware selection of input / output modules The selection of the type of modules should be based mainly on the technical requirements, on […]
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 […]
