楼上大侠说的有点问题。请看CP1623发布说明：

----Compatibility with CP 1613
The CP 1623 can be used for all applications in which the CP1613 or CP1613 A2 were employed up to now, without having to change the configuration or the user software. The CP 1613 configuration can thus be downloaded to the CP 1623 in STEP 7/NCM PC. The only precondition is the use of the SIMATIC NET CD with version 2007 + Hotfix 1 or higher.---
只要安装的是CD2007 hotfix 1(也就是V7.0)或更高版本，你直接使用组态为CP1613/CP1613A2的配置项目.
