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、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.
