[?]: What is the difference between S7-200 CN and EU/US Plcs
Posted: Mon Nov 15, 2010 12:45 pm
Good morning. I was looking for a good offer for a 224XP plc on Ebay,
and I found a pair of resellers who sells Siemens 200 plcs with the label "S7-2xx CN", with "CN" meaning "made in China and for chinese market".
It seems that this plcs are exactly identical to the ones sold in Europe or in U.S., but for commercial reasons are sold (at a lower price) only in China.
Looking around the web I found sombody that has tested this kind of plcs, and the main problem is that programs can be uploaded on the plc with Microwin only if the software language is changed to Chinese; anyway, the program can be written in any language one wants, only the Microwin language must be switched to Chinese to upload the program on the plc (this is what is written on 2-3 forums).
I want to ask you if anybody has any experience with these Chinese products, if they can really be programmed with standard Microwin, and if there could be any problem of reliability with them.
Thank you in advance.
