西门子国外的论坛就是好，中文论坛能否也像他们一样，有西门子的技术专家来回答呢。
我的帖子是基于以下网址稍微翻译过来的：

WinCC Flexible是ProTool的替代产品，主要用来给西门子的操作屏（OPxx, TPxx, MPxxx）编程。但是如果需要的话，也可用在PC机上作Runtime程序，用作单站的SCADA应用。
WinCC是西门子完整的SCADA包，不仅仅用来操作项目，而且可用来作数据采集、网络服务器、冗余、时间监控，历史查询等。WinCC仅仅在PC上运行，而且体系架构比较大，分为服务器和客户端，比WinCC Flexible强大和复杂得多。
可以通过https://www.automation.siemens.com/hmi/index_76.htm?HTTPS=REDIR获取一些相关信息。
WinCC Flexible在功能上逐渐与WinCC靠近，有可能两者合为一体（现在的区别还是很大的。）




Hello dcabana23;
WinCC Flexible (replacement product for ProTool) is basically an HMI programming software. Its main design is to program Siemens operator panels (OPxx, TPxx, MPxxx) for operator interface, but it also comes in a PC-based Runtime if required.
WinCC 6.2 is Siemens' full-fledged SCADA package, designed not only to allow operation of the project but also data acquisition, web servers, redundancy... It only runs on a PC (or PC combination as in server/client applications), and is much more powerful (and complex) than its Flexible cousin.
To find out more details on these Siemens products, have a look at the Siemens HMI portal here:
https://www.automation.siemens.com/hmi/index_76.htm?HTTPS=REDIR
You can have access to brochures and technical data (data sheets and manuals) on both products if you need to understand this fully.
Hope this helps,
Daniel Chartier



As Daniel said, with WinCC Flexible you can configure Siemens' operating panels and small SCADA stand-alone stations. It has more features than ProTool. I've heard that Siemens intends to supply only one HMI engineering tool, so WinCC Flexible was created to put panel programmers a little closer to WinCC, and in the future they would become only one tool.
With WinCC you can have more advanced features, and options which provide some level 3 features (such as downtime monitor, historian...) and larger architectures, with client-server environments.
Here's some info on WinCC and WinCC Flexible. Notice that both have interesting options, and that WinCC Flexible has different kinds of licence, so you should get to know the differences between them a little to specify the system.
Best regards,

Danielle
