Should I use a managed switch or an unmanaged switch with PROFINET? Spoiler answer: Yes. Read the whole thing for the long answer and the “why.”
Again, the short answer is “yes.” But the post tells where we use it and why we do not use it everywhere.
This post begins:
I was amused by these dueling viewpoints in recent Control Engineering articles:
- Ethernet for sensor networks? Why it makes sense today
- Consider a sensor network to ease connections (not Ethernet)
The post turns from amusement to answers.
Related to the question of PROFINET really, really just using Ethernet, this post shows how even an inexpensive Ethernet switch works for PROFINET.
A research study showed that the number one industrial Ethernet is “Ethernet.” Leading me to rant that Ethernet is not a protocol. Complete with diagrams and many reader comments.
Four (out of five) IT protocols benefit PROFINET – here’s how.
If there is a short answer to this question, it’s “maybe.” But PROFINET is as deterministic as you need it to be.
This post is kind of dated. Now I would not mention CBA, but inform readers that PROFINET can send real-time data using UDP which is routable.
A common question answered.
This is such a common question that we recently expanded on the answer in PROFINEWS- Tech Tip: How Many Devices on a PROFIBUS Network?
