I have over a decade of experience with Omron as well. Haven't worked on a Mitsu project since 2013. I have over a decade of experience with Mitsubishi's older series like Q, iQ, and FX. However I believe that these are just as valid, after all everyone has to work with these things and experiences them differently dependent on application. Thanks for the detailed response! I can understand your concern about people answering with their feelings rather than facts. I look forward to the responses to see how each fairs on a SWOT analysis. All three have broad offerings that all integrated within their families. All three companies make great products that can control most any process. They are all partially right because each one has their own unique measure of their claims that do not consider what the competitors claim. Each manufacturer provides claims that their product is easiest to use, has the fastest processor, the broadest instruction set, the most robust hardware. Strenths, weaknesses, opportunities and threats are all dependent on the individual or company making the analysis as it relates to their particular situation and needs. I have purposely not answered your question specifically because there are so many variables. I would think the same situation happens with any of the manufacturers if you are trying to source something away from any their "home" continent. I have not typically had this issue with Allen Bradley. I have had issues with Mitsubishi and Siemens with lead times on replacement parts because I am in the metro Detroit area. These three companies have huge presence in the world, but they don't have everything everywhere. All of them have inventory in all major areas, but not all inventory. THREATS - Again, geography can come to play with all of these companies. The main thing that has determined which of those companies are selected in those industries starts with location and the available inventory, support and software. All three are in the steel industry and automotive industries, for example. Each of the three have their core industries that they serve and that is highly dependent on the location of the industry. OPPORTUNITIES - This is highly dependent on the industry being served. The company that doesn't have the best software has generally made up for that by making a nearly seamless upgrade path as hardware becomes obsolete. Two of the companies generally have better software than the third. It is a general rule, not an absolute for EVERYONE who supports the products.) Two of the above companies are GENERALLY more expensive than the other. (Don't get offended if you offer great support for one of those companies outside of the areas listed. The best support for Mitsubishi is going to be in Asia, the best support for Siemens is going to be Europe and the best support for Allen Bradley is going to be North America. Geography has a lot to do with the support. WEAKNESSES - The biggest potential weaknesses from my viewpoint are cost and support with software a close third. All three offer world-class hardware and capabilities. In my opinion, two of the three have decent software and one has always lagged. STRENGTHS - consider cost, availability of product and support personnel. I will provide my viewpoint without really endorsing any one brand. There is potential for high emotions and lots of cheerleading for or against certain manufacturers. This is one of those topics where people are going to answer 'absolutely' based on their experience.
