About The FRL


The Fieldbus Reference List (FRL) started off in 1993 with a comparison between two industrial networks, which my manager requested. I then also started collecting information about these networks, most of which was on paper because the Internet hardly existed at that moment.

Later on, my manager wanted a third network added. I then automatically added more networks to the comparison, as ammunition for the sales people so they could answer any question from (potential) customers or counter any critique.

In 1996, the Internet came into being. Because I worked for a company which made industrial controllers, we were confronted with questions about the most exotic networks. I started collecting URL's, just to be prepared to answer questions from the sales staff. As I felt that the list would be of use for others as well, but the company at that time did not understand the need for an own website, I could not publish it  there.

Instead, I resorted to the Control.com maillist, on which it was irregularly posted. I also published the list in magazines such as Elektronica (Dutch) and Elektronik (German).

When I left the company in 1997, I temporarily lost interest in the list. It came back in 1998, and since then I checked all URL's every two months, and posted the results in the Control.com maillist. From there it was picked up by others, some of whom made their own pages based on my posting, and even a few put their own name under it.

To my surprise, the list grew and grew and still there seems to come no end to the number of new systems. One would have thought that by know it would be clear that there are too many "open" networks. Since 1999, the list grew even faster because a lot of systems hunted for standardization by ISO, IEC, CENELEC, EIA and IEEE (or any combination thereof, or even more than once). That's when I started adding references to (inter)national standards.

In 2000, I started adding references to user's groups and trade associations, literature (books), magazines, email lists, archives, and my own courses. So I hope that the Fieldbus Reference List can truly be seen as a portal to all information sources about industrial networks that existon the WWW.
