It’s Independence Day in the USA, the Fourth of July. PROFINET connection coming up, but first…
“Independence Day” always reminds me of the movie (the original one, where a virus created on a Mac laptop can infect an alien operating system) and the old joke “Daddy, does Canada have a fourth of July? Yes, son, it’s between July third and fifth.”
In the USA, it marks the day in 1776 when the Declaration of Independence was publicly announced. Part of it reads:
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
I’ve taken the liberty (see what I did there) of rewording it to apply to PROFINET:
We hold these truths to be self-evident, that not all networks are created equal, that they are endowed by their market with certain unalienable shares…
PROFINET is number one in the market. I get amused when also-rans claim market dominance. (See last week’s post, We’re Number One.)
And PROFINET is really independent. The Intellectual Property (IP) is owned by PI, not any single company. Contrast that with EtherCAT whose IP is owned by just one company.
