shine：我在用到fuzzycontrol++与s7-300连接时，有段帮助如下：
You must connect a SIMATIC S7 system via an MPI (multipoint interface) card. Use the SIMATIC NET software "COML S7" (for SOFTNET S7 PROFIBUS) to configure the connection.
Before establishing the connection, you must specify your connection more precisely in a dialog box.

- First you must state where the SIMATIC Communication Software "S732.DLL" is located on your computer. The default for the complete path to this file is "C:\SINEC\SAPI_S7.W95\LIB\S732.DLL". If this DLL is in another directory on your computer, you can click on "Browse..." to select it or enter the full path name directly.
- Enter the name of the online interface configured with COML S7. You can use the preset interface "S7ONLINE" (default).
- Enter the name of the VFD (Virtual Field Device). The S7 connections are assigned under this VFD name. If you want to connect several projects with the targetsystem at once, all the open projects must have different VFD names!

- If you have already configured a connection, you must state the connection name (as configured in COML).
- If you have not configured a connection, you can enter the MPI address of the CPU directly (between 0 and 126), the S7 rack (between 0 and 7) and the slot used in the rack (between 0 and 18).
- Finally you must enter the number of the fuzzy data block on the S7-CPU (between 0 and 999999).

当我把s732.dll的路径导入时，程序就跳掉了，我用的simatic net是6.1版的，是不是一定要用3.3版中的S732.DLL啊？而且新版的simatic net没有coml s7啊？哪位高手帮忙啊！我都困扰好长时间了！郁闷ing!
