All the Major Fieldbus Protocols in One Course?

We just started offering an online Fieldbus course that proclaims <i>"No other Fieldbus training course in the world includes all of these protocols in one package!"</i>

I thought, that is a pretty big claim, but because my own experience in Fieldbus technology is limited, I though it best to ask the group ... "what are the most popular <b>Fieldbus protocols</b>?

The online Fieldbus course covers FOUNDATION Fieldbus, Profibus PA, HART and ASibus. Is there one or more Fieldbus protocols that is more popular than the 4 above?

More important to verifying the claim, do you know of any other online Fieldbus course that covers all 4 protocols?

Thanks for you help.
 
Some may not call them 'fieldbuses' but the two most popular Industrial networks used for Remote I/O and Communications today are ProfiNet and Ethernet/IP.

First hit on Google for "Fieldbus market share"

But there are some problems with your question and my answer. First of all, if you confine the question to specifically the process industry, the data undoubtedly changes. I mention this because FF, Profibus PA, and HART are concentrated in the process industry. You'll note that FF and Profibus PA aren't even on the chart. Meanwhile, FF claims a "68 percent market share in the process industries." http://www.fieldbus.org/index.php?option=com_content&task=view&id=148&Itemid=312

AS-i is NOT a process fieldbus. It's odd to see it with those other three. HART isn't a fieldbus at all, it's a point-to-point communication protocol. It is, however, predominantly in the process industry.

Are there other popular fieldbuses? Absolutely. DeviceNet, CANopen, and even CC-link beat out AS-i, and presumably both FF and Profibus PA. Regular Profibus dwarfs just about everything. You don't mention Modbus, which is also not a fieldbus, but a very common protocol.

I don't know of any course that covers those 4 protocols. This is not surprising; FF and Profibus PA are mortal enemies, and AS-i doesn't fit well. I'd say it's a safe claim.
