安装gsd文件时出现错误代码13：4343怎么解决

在安装GSD时，要关闭STEP7的一些窗口。
1、有关13:4343错误：
13:4343 ： An update is presently not possible. In one or more STEP 7 applications at least one GSE file or type file is being referenced.
2、原因：
In the different S7 applications there are objects (stations) open in which DP slaves are used. Thus it is no longer possible to install new GSD or type files, or even to update them.
3、解决办法：
Please close the station window in the hardware configuration and all other STEP7 applications (such as NETPRO, for example) that could access the GSD file . The Hardware Configuration application remains open however without content. Then you can install the GSD file.
