PLCstyrda
PLCstyrda, a Swedish term for PLC-controlled systems, refers to automation setups in which a programmable logic controller coordinates and supervises electromechanical devices and sensors. PLCs are rugged, real-time digital computers designed to handle discrete and event-driven control tasks in industrial environments.
Typical architecture includes a PLC CPU, input/output modules, a power supply, and programming/interface devices; fieldbus or
Common applications include manufacturing lines, packaging, material handling, robotic cells, water treatment, and process control in
Advantages include deterministic timing, high reliability, straightforwardDiagnostics, scalability, and cost-effectiveness for discrete control. Limitations include less
Historically, the PLC concept emerged in the 1960s to replace relay-based controllers, and modern PLCs offer
