Engineering through the Ages

Why technology needs languages and how Selmo is the language of logic and programming

For centuries, humans have sought ways to describe technology clearly and understandably to describe. Because only with a language can ideas, designs and functions be shared worldwide.

• In mechanics it is the technical drawing, that makes dimensions, shapes and tolerances unambiguous.

• In electrical engineering it is the circuit diagram, that describes electrical connections and functions.

• In manufacturing it is the G-code, that standardizes the control of movements and machining.

But in the logic of machines there has been a gap since 1968: with the invention of the PLC the clarity of circuit-diagram logic was lost.

This document traces the history of technical languages shows the transitions and clarifies how Selmo closes this gap again.
