[Background] In April 2025, a move by Audi’s Böllinger Höfe factory in Germany shocked the automation industry: they removed 200 traditional PLCs from the production line and replaced them with virtual PLCs (vPLCs) running on Siemens’ cloud. The control logic shifted from “hardware next to the machine” to “software in a data center kilometers away,” … Read more
Currently, there are 5 standard programming languages for PLCs, including graphical programming languages and textual programming languages. Graphical programming languages include: Ladder Diagram (LD); Function Block Diagram (FBD); Sequential Function Chart (SFC). Textual programming languages include: Instruction List (IL) & Structured Text (ST). The programming languages of IEC 1131-3 are a set of international programming … Read more
