你好，
我使用Google的专有技术是不够的还是......

至少我没有找到任何可公开获得的模块作为OPC /现场总线这样的物品沟通等...
TIA，
最好的问候，

Hello,
is it that my know-how to use Google is insufficient or...
....does really noone use Python for industrial control applications?
At least I didn''t manage to find any publicly available modules for such
things as OPC/fieldbus communication etc...
TIA,
best regards,

I do -- I use Python to do DeviceNet stuff.

我找不到任何公开可用的DeviceNet模块
_any_ language 。这并不意味着没有人在编写与DeviceNet相关的程序
。 ;）

I couldn''t find any publically available DeviceNet modules for
_any_ language. That doesn''t mean nobody is writing programs
that talk DeviceNet. ;)

我去了OPC一次。我有一个工作简单的OPC客户端我认为
（无法让服务器正常工作）。
基本上OPC都是COM所以它应该对win32com来说太难了方法

I had a go at OPC once. I had a working simple OPC client I think
(couldn''t get the server working).
Basically OPC is all COM so it should be too hard with the win32com methods

这些东西不一定会浮入开源。我的冒险经历/ b $ b OPC涉及Python和C ++代码 - 我目前对
Python的了解可能会有更少的C ++代码:-)。 OPC只是DCOM，它应该直接使用Python + pywin32扩展名
（以前称为win32all，这可能有助于你的google搜索）。获取
Mark Hammond在Win32上编写Python编程的书：
http://www.oreilly.com/catalog/pythonwin32/
或者，您可以购买/找到一个C库，使OPC简单
（即不需要处理w / COM），并用Python包装。
和BTW，OPC很糟糕。这些工业决策者在他们提出使用DCOM作为
集成商面向界面的想法时，必须已经吸了大量的破解。
直截了当。

People are known to do this.

Such things don''t necessarily float into open source. My adventures w/
OPC involved both Python and C++ code - with my current knowledge of
Python there would probably have been much less C++ code :-). OPC is
just DCOM, which should work directly w/ Python+pywin32 extensions
(used to be called win32all, which might help your googlings). Get
Mark Hammond''s book Python Programming on Win32:
http://www.oreilly.com/catalog/pythonwin32/
Alternatively, you could buy/find a C library that makes OPC simple
(i.e. no need to deal w/ COM), and wrap it up in Python.
And BTW, OPC sucks. Those industrial decision makers must have smoked
lots of crack when they came up w/ the idea of using DCOM as the
integrator-facing interface that is supposed to be easy and
straightforward.
