Most Popular PLC in Spain?

I have an opportunity to do some design for a control system in Spain, and I may have the panels built there. Is Siemens still the most popular PLC in the E.C.? How about the most popular in Spain specifically? What recommendations do you guys have for PLC and O/I platforms? What ones should I avoid? I'd prefer brands that have good US support as well, since I'll be providing the programming.

I can't really comment on Spain Tom as I have never worked there, but Seimens PLC's are very popular within Europe, well the UK anyway and apparently we are part of Europe (sorry this is a PLC forum not a political one)

I think that Siemens and Schneider Electric (Telemecanique) are two of the most popular PLCs in Europe, well at least according to the marketing types. Will programming language be part of your consideration?

Programming language is definitely a consideration. We will be using ladder logic, since we have done all of this before and porting the program to another platform in ladder logic is not a big deal. (Another reason I avoid "clever" programming techniques!)

I would say go with Siemens, it is a European brand and probably one with the best support etc overall. Their Johnson City, TN facility here has been awesomely helpful for me. They can use Profibus, DeviceNet, etc etc. If its a small system you may like the S7-200 (because of its similarities with old TI/Siemens/automationdirect plc's and programming) but the S7-300/400 has an abundance of features and options (the software, hardware and ladder format need some time to get use too but something that would not be difficult for you).You may want to look at the Siemens website at the products and support features:

Klockner-Moeller (which I have mixed feelings for) is another common brand for Germany and Italy, not sure about Spain.

Of course Telemecanique/Modicon is well known and used:

The one I would most definitely avoid is ABB. I can not find support for it here (maybe better in Europe) and finding parts is difficult with long lead times.

It depends of the size of your project.
I live in east part of Spain, Valencia.
Here you will find OMRON and SCHNEIDER
Bigger projects SIEMENS and ALLEN BRADLEY.
GOOD LUCK
