AB Micrologix 1200-连接＆amp;使用.NET获取数据
我是.NET程序员，对Plc＆amp; HMI。
我有一个即将到来的项目，该项目需要阅读Allen-Bradley PLC Micrologix 1200的数据。我搜索了有关将PLC连接到计算机以阅读PLC的数据的可用内容，从而找到了一种IE Modbus。
您能帮我吗：
- 连接到AB Micrologix 1200的最简单方法是什么？
- Micrologix 1200上的一个COM端口已经连接到HMI，没有其他端口可用，可以完成连接的方法？
- 哪个库最适合连接到AB PLC。
请指导。
谢谢。
I am .net programmer and Know Little bit about PLC & HMI.
I have an upcoming project which required to read data from Allen-Bradley PLC Micrologix 1200. I searched through Online Available Content about connecting PLC to Computer for reading the data from PLC, found one way i.e. MODBUS.
Can you help me regarding :
- What will be the easiest way of connecting to AB Micrologix 1200.
- One COM Port on Micrologix 1200 is already connected to HMI and there is no another port available, what will be the way to accomplish connection?
- Which Library is best suitable for connecting to AB PLC.
Please guide.
Thanks.

我不是艾伦·布拉德利（Allen-Bradley）的专家，但是似乎该PLC模型具有Modbus RTU，如果您的HMI使用了同一网络，只要您使用网络照顾，您就可以与您的监督系统一起加入它设置，Adresses ...
否则，您可以搜索一些扩展模块，以包括另一个网络端口。
我认为Modbus RTU对您来说将是最简单的选择之一，互联网上有很多示例。一个例外是数据量和速度至关重要，在这种情况下，基于以太网的网络或其他内容会更好。
我尝试了一些示例来自 mesta-automation ，看看这篇文章，我认为，我认为对您来说，这可能是一个很好的起点。
I'm not an expert in Allen-Bradley, but it seems that this PLC model has Modbus RTU, if your HMI is using this same network, you can possibly join it with your supervisory system, as long as you take care with the network setup, Adresses...
Otherwise, you could search for some expansion module to include one more network port.
I think Modbus RTU would be one of the easiest options for you, there are tons of examples on the internet. An exception will be if data volume and speed are critical, in which case an ethernet-based network or something else would be better.
I've tried some examples from Mesta-Automation, take a look at this article, I think it might be a good starting point for you.
