串行字符串输出 [英] Serial String Output

问题描述

我是这个表格的新手并且通常不会用C编程＃我是更多的SCADA / PLC / VB人员并且可以真正使用一些帮助。

我是目前正在WinCE 6中运行Beijer iX应用程序的HMI面板上，该应用程序使用C＃作为其脚本。

然后我的问题，

我必须发送一个数据字符串（使用RS232端口）到另一台计算机（在电缆铺设船上进行测量），字符串需要由HMI标签数据库中的各种标签组成。

我可以访问COM端口和发送数据，但只能从屏幕按钮，我真的需要为此设置1秒计时器，到目前为止，我无法弄清楚如何构建要发送的字符串。



我很久以前就用VB编写了这个程序，但到目前为止C＃让我难倒了



任何帮助/指针都会非常感激



谢谢

I''m new to this form and don''t normally program in C# I''m more SCADA/PLC/VB guy and could really use some help.
I''m currently working on an HMI panel running a Beijer iX application in WinCE 6, the app uses C# for its scripts.
My problem then,
I have to send a data string (using an RS232 port) to another computer (survey spread on a cable lay ship), the string needs to be made up from various tags from the HMI tag database.
I can access the COM port and send data out, but only from a screen button and I really need to setup a 1 second timer for this and so far I cannot work out how to build the string to send.

I have written this very program in VB a long time back but so far C# has got me stumped

Any help/pointers would be greatly appreciated

Thanks

推荐答案

最好的实现的方式即使用 SerialPort [ ^ ]类，有几个方法，属性和事件。



C＃示例：使用C＃和Whidbey的串行通信 [ ^ ]

基本串口侦听应用程序 [ ^ ]



VB.NET中的示例： http://msmvps.com/blogs/coad/archive/2005/03/23/SerialPort-_2800_RS_2D00_232-Serial-COM-Port_2900_-in- C_2300 _-。NET.aspx [ ^ ]



要在一段时间内发送/接收数据，使用计时器 [ ^ ] class，example：如何在C＃中使用定时器控件 [ ^ ]

The best way to achieve that is to use SerialPort[^] class, with its several methids, properties and events.

Example in C#: Serial Communication using C# and Whidbey[^]
Basic serial port listening application[^]

Example in VB.NET: http://msmvps.com/blogs/coad/archive/2005/03/23/SerialPort-_2800_RS_2D00_232-Serial-COM-Port_2900_-in-C_2300_-.NET.aspx[^]

To send/receive data in a period of time, use timer[^] class, example: How to use timer control in C#[^]
