The terms “master” and “slave” have long been used in technology to describe the relationship between a controlling device (master) and a subordinate or controlled device (slave). This terminology, while deeply embedded in various technical disciplines, has its roots in a darker chapter of human history. The terminology brings to mind the harsh realities of human enslavement, a history that is incompatible with the values of modern society. As awareness of these historical connotations has grown, so too has the recognition that such terms are not appropriate in a professional and inclusive environment.
In recent years, there has been a significant movement within the technological and industrial sectors to move away from using “master” and “slave” in favour of more neutral terminology. One of the key drivers of this change is PROFIBUS and PROFINET International (PI), a global organisation that sets standards for industrial communication. PI has confirmed it is planning to stop using the terms “master” and “slave” in its publications, new specifications, and related materials, and has already begun cleaning up its website, marketing communications, and brochures.
Following in PI’s footsteps, IDX has also decided to adopt this new terminology. We will be updating our terminology by replacing “master” with “controller” and “slave” with “device.” In response to these changes, we have updated our blog and website to reflect the new terminology, and we are currently in the process of updating all supplier products listed on our website.
We believe that terminology matters and the words we choose should reflect our commitment to inclusivity. By aligning with PI’s updated standards, we aim to eliminate terms that may be offensive, ensuring that our terminology is as welcoming as the environments we strive to create. As we continue this transition, we remain committed to ensuring that our industry moves forward in a way that is mindful of history and respectful of all individuals.
