想从一个win应用程序直接打开step7并跳转到我需要的位置，比如FC10-NW8，看了西门子的帮助文件还是云里雾里，不太明白，不知有高人否请教一下：

我现在的问题1，如果采用这种方式启动step7   /e F:\SIEMENS\STEP7\S7proj\MyConfig\MyConfig.s7p /keep  ，并不能跳转到我需要的位置，而且我试过不会报错，但是打开后项目是空白的。

问题2，这种方式不太明白前面的1,8什么意思，实际情况也打不开，从帮助看，即使打开了，也跳转不到我需要的network。

/o "1,8:MyConfig\SIMATIC 400(1)\CPU416-1\S7-Program(1)\Blocks\FB1"

以下是从帮助文件copy的

Starting STEP 7 with Default Start Parameters

From STEP 7 V5.0 onwards, you can create several symbols in the SIMATIC Manager and specify start parameters in the call line. By doing this, you can cause the SIMATIC Manager to position on the object described by these parameters. This allows you to jump to the corresponding locations in a project immediately just by double-clicking.

On calling s7tgtopx.exe, you can specify the following start parameters:

/e <complete physical project path>

/o <logical path of the object on which you want to position>

/h <ObjectID>

/onl

The start parameter /onl causes the project to be opened online and the specified path to be called.

/off

The start parameter /off causes the project to be opened offline and the specified path to be called.

/keep

The start parameter /keep causes the following to occur:

If the SIMATIC Manager is open, the already displayed projects are opened in addition to the new project to be explicitly opened by means of the command line. If the SIMATIC Manager is not yet open, then the new project is opened along with the projects stored in the session memory of the SIMATIC Manager. If this start parameter is not specified, the opened projects are closed first, the session memory is ignored and only the one specified project is opened.

/noopen

The start parameter /noopen causes no project to be opened when SIMATIC Manager is started.

The easiest way to establish suitable parameters is described below.

Establishing Parameters by Copying and Pasting

Proceed as follows:

On your desktop, create a new link to the file s7tgtopx.exe. This file is located in the installation directory under S7bin.

Display the properties dialog box.

Select the "Link" tab. The entry under "Target" should now be expanded as follows.

Select the required object in the SIMATIC Manager.

Copy the object to the clipboard using the key combination CTRL+ALT+C.

Position the cursor at the end of the "Target" entry in the "Link" tab.

Paste the contents of the clipboard using the key combination CTRL+V.

Close the dialog box by confirming with "OK."

Example of Parameters:

/e F:\SIEMENS\STEP7\S7proj\MyConfig\MyConfig.s7p /keep

/o "1,8:MyConfig\SIMATIC 400(1)\CPU416-1\S7-Program(1)\Blocks\FB1"

/h T00112001;129;T00116001;1;T00116101;16e /keep
