最佳答案
正确的安装步骤：
Both S7-200 PC Access and STEP 7- Micro/WIN are installed
You must upgrade both applications to the latest versions for correct operation.
1) Contact Siemens customer support and obtain access to both upgrade installations from a Siemens FTP server.
2) Run either the STEP 7- Micro/WIN V4.0 SP9 upgrade or the S7-200 PC Access V1.0 SP6 upgrade.
3) Uninstall STEP 7- Micro/WIN.
4) Uninstall S7-200 PC Access.
5) Run STEP 7- Micro/WIN V4.0 SP9 upgrade.
6) Run S7-200 PC Access V1.0 SP6 upgrade.
A previous version of only one application is installed and you want to install the latest version of the other application
For example, an older version of the STEP7- Micro/WIN is installed and you want the latest version of S7-200 PC Access. You must upgrade the old application to the latest version and then install the latest individual license version for the new application. Upgrading the old application is necessary for correct operation.
