As stated SCL is included in Step7 Professional but you can buy SCL as a standalone package to regular Step7

Hello globalpositionning;
You should contact Siemens Mexico, they are the best people to give you the kind of information you are looking for, especially local distributors in your area: eBusiness Partner Siemens SA de CV, México, D.F. ST IA Mr.Arturo Rivero
Do you know what version of Step 7 you currently have installed? If you need to upgrade to version 5.4 then I would go to Step 7 PROFESSIONAL. That would give you SCL and the SIM program. If you just need the SCL and want to go cheap you may find SCL stand alone but be carefull about the version capatability. I would go to Step 7 Pro, regardless.
Sorry GP,
the link provided earlier came from Siemens.com, worldwide contacts. Today I am also recieving "404-Webpage does not exist" messages from my browser.
However, in the Siemens Industry Contacts database (for México), you will find other links, look on this page: https://www.automation.siemens.com/...ion-technology/Pages/default.aspx?HTTPS=REDIR
