iFIX工程开发流程

iFIX工程开发流程作者：lostcity一、预备知识。

开发一个项目，首先当然需要明确该项目的需求了。

项目完成后要实现什么样的功能，实现那些功能需要什么样的设备、软件支持等。

大概罗列一下，我想这是必须的。

我们假设要实现这样的一个简单系统：使用iFIX监控三菱Q系列的plc，包括数据读写，数据历史存储，数据和报警动态监控等。

于是很自然在开发系统之前我们需要预备的东西就包括：Q系列plc的监控点表，iFIX软件和Q的通信驱动等。

这一切准备好了，才能开始上位i FIX工程开发。

二、iFIX工程开发流程。

当准备工作完毕，开发工作也就可以开始了。

1、软件的安装，包括iFIX和驱动。

这个不说了，不会得自己想办法去吧。

如果要使用OFFICE，O FFICE必须先于iFIX安装，如果先装了iFIX，请先卸载iFIX，再装OFF ICE，然后装iFIX。

2、真正开始是这里：系统配置（SCU）所谓系统配置，就是为系统配置一些参数，以后开发系统过程中可以直接使用。

这些配置信息保存成一个scu文件，iFIX启动的时候可以选择装载哪个文件。

系统配置包括有：系统路径配置：这个简单，默认就可以。

意思无非就是哪部分的数据/配置数据储存在哪个位置。

值得说的是如果打算开发多个项目，那么可以为每个项目设置不同的“工程项目”路径。

（参考视频教程之"多工程"）报警配置：报警的配置包括报警打印、报警信息摘要、报警文件、报警历史、报警odbc、网络报警、报警队列等。

每一项服务的意思都比较容易理解，根据项目需要启动相关服务就可以了。

网络配置：这个视需要设定，如果不使用网络功能就不用管他，使用的话把远程的iFIX节点添加进去也很简单。

SCADA配置：直说就是启用scada和为工程添加通信驱动。

注意这里只是添加，驱动配置步骤在后头。

客户端的话可以不使用scada支持。

启动任务：iFIX启动的时候需要伴随启动那些程序，统统加进去，还可以选择启动方式。

安全和SQL用户配置：设置用户权限以保证系统安全。

可以不用管，需要用再看电子书。

3、驱动配置（i/0 driver configuration）iFIX为用户提供两种类型的驱动程序，一种是6x另外一种是7x，区别在于7x可以作为opc server而6x则不可以。

另外关于6x驱动的安装可以参考6x驱动安装说明。

还有就是这些驱动的配置界面虽然比较接近，但是还是有不大一样的地方，这需要看具体那一款驱动，相同的基本上都包括：设备（devi ce，对应的就是通信设备，一般需要配置相关通信参数）、组（group，为标签点分组方便管理）、标签（item，和设备点相对应）等。

参考视频教程之"驱动配置"4、数据库配置（process database development）在驱动配置完毕之后，就需要进行数据库标签点的添加了。

主要操作就是为每一个io点（在驱动中已经添加了相应的item）在数据库中增加一个相对应的数据库标签点（他们之间是以io地址进行对应的，跟item和标签点名字无关），然后为这些数据库标签点指定相应的属性（包括：io地址、扫描时间、报警信息、安全区等）。

当然，如果标签点很多，也可以使用标签点的导入导出功能和excel辅助配置。

5、报警配置和监视（alarm configuration/monitoring）报警配置主要是根据需要为系统划分的相应报警区域，并对这些报警区域的报警点进行监控操作。

数据点增加的同时，根据需要为每个数据点划分到相应报警区域，这样可以方便以后报警的管理和察看。

6、历史归档（configure data archiving）不论当前节点是否支持sacda，都可以使用历史归档。

历史归档主要对部分重要数据按规则进行存储，在系统正常运行之后仍能回顾较前的运行数据。

历史归档的配置也相对简单，可以根据需要设定历史参数。

7、安全配置（security configuration）这个容易理解，就是为每一个用户相应操作的权限，使得用户在运行环境下具有相应级别的权限。

参考视频教程之"安全"8、画面设计（graphics development）上面提到的都是后台的操作，而真正呈现在最终使用者面前的是我们设计的监控画面。

当一切后台配置都完成之后，最后就到了监控画面的设计上了。

画面的设计主要用到这些对象：数据戳（datalink），报警摘要（a larmsummury），画面专家，数据点专家等。

如果需要更多功能还可以使用内嵌得vba脚本进行编写程序。

总之画面设计这一块可以发挥全部才华，做出想要的效果。

三、开发完之后当然还要发布和测试，当再没有发现大问题的时候工程也就差不多了。
