#343 Weaving Software into Automation

September 11, 2025

Joseph-Marie Jacquard invented the punch card as a means of inputting control data to one of the earliest automated technologies, the weavers’ loom. A generation later, Charles Babbage used this innovation as part of his design for an ‘analytical engine’, and Ada Lovelace demonstrated how sets of instructions could be written for the engine to enable any computing task. 

Almost two centuries on from Babbage and Lovelace’s invention of computing hardware and software, IT (information technology) and OT (operational technology) have evolved into parallel threads. On the production line, automation engineers use visual languages, based on electrical relays, on rugged computers, or PLCs, that lack connections to the wider internet. In the office, software developers write code using text-based languages, with sophisticated systems for deploying updates, and the ability to connect over the internet to AI powered services.

Now, the warp of IT and the weft of OT are being woven together. Software-defined automation links machinery on the production floor to IT systems, and the wider Internet. Control code can be written in text-based languages using object-oriented programming, and deployed to factories around the world at a click. Automations, human-machine interfaces, and all other aspects of control systems can be developed and tested on simulated equipment, rather than waiting for prototypes to be built. 

Easy data exchange fuels efficiency and value. In this episode, we learn how automation engineers like Loupe are using a software-defined approach to speed the development of cutting edge industrial systems. We discover how a new organisation, SASE, or the Society of Automation Software Engineers, is helping define this new interwoven specialism. And we explore how one industrial automation specialist, MTS, is openly sharing its automation code, allowing for industry to be transformed by the same community development approach that has driven the success of the tech sector.
