Use this Document Update inconjunction with the following GML Ultra publications dated February 1997:•Getting Started Manual (publication 1398-5.10)•User Manual (publication 1398-5.11)•Reference Manual (publication 1398-5.12)Getting StartedManualPage 5-7Add the following I/O configuration option sub-menu at the end of step 2 of theConfiguring User-Defined Input section:Page 5-16Add the following information at the end of the Defining I/O Configurationsection:Configuring User-Defined DefaultsThe default outputs settings determine the state that the outputs will be set towhen a program is stopped. Each output can be set to either turn ON, turnOFF, or remain unchanged when program execution is halted. These settingsaffect the output if the program stops (for example, loss of enable, an error, orthe end-of-program reached).The default outputs settings only affect the nondedicated, general purposeoutputs.

You can use the Redefine Position block when the axis is moving or at rest. This block does not cause motion; it simply redefines the current axis position.Important: Use caution if you use this command while there ismotion. The time delay caused by execution speed results in the zero position being defined at a position that is different than when the command was issued. The difference in position is proportional to the velocity of the motor when the command was issued.

log4net使用手册1 简介1.1Log4net的优点：几乎所有的大型应用都会有自己的用于跟踪调试的API。

因为一旦程序被部署以后，就不太可能再利用专门的调试工具了。

然而一个管理员可能需要有一套强大的日志系统来诊断和修复配置上的问题。

经验表明，日志记录往往是软件开发周期中的重要组成部分。

它具有以下几个优点：它可以提供应用程序运行时的精确环境，可供开发人员尽快找到应用程序中的Bug；一旦在程序中加入了Log 输出代码，程序运行过程中就能生成并输出日志信息而无需人工干预。

另外，日志信息可以输出到不同的地方（控制台，文件等）以备以后研究之用。

Log4net就是为这样一个目的设计的，用于.NET开发环境的日志记录包。

1.2Log4net的安装：用户可以从/log4net/下载log4net的源代码。

解压软件包后，在解压的src目录下将log4net.sln载入Visual Studio .NET，编译后可以得到log4net.dll。

用户要在自己的程序里加入日志功能，只需将log4net.dll引入工程即可。

2 Log4net的结构log4net 有四种主要的组件，分别是Logger（记录器）, Repository（库）, Appender（附着器）以及Layout（布局）.2.1Logger2.1.1 Logger接口Logger是应用程序需要交互的主要组件，它用来产生日志消息。

产生的日志消息并不直接显示，还要预先经过Layout的格式化处理后才会输出。

Logger提供了多种方式来记录一个日志消息，你可以在你的应用程序里创建多个Logger，每个实例化的Logger对象都被log4net框架作为命名实体(named entity)来维护。

这意味着为了重用Logger对象，你不必将它在不同的类或对象间传递，只需要用它的名字为参数调用就可以了。

log4net框架使用继承体系，继承体系类似于.NET中的名字空间。
