How to Troubleshoot the Error?
To troubleshoot this error, you need to check three aspects: the network connection, the Windows user account settings, and the network access rights. Here are some steps you can follow:
Check the network connection between the engineering station and the target station
You can use two tools to check the network connection: the ping command and the SIMATIC Shell tool.
Open a command prompt on your ES and type "ping " or "ping " of your target station. If you get a reply, it means your network connection is working. If you get a timeout or an error message, it means your network connection is not working.
Open SIMATIC Shell on your ES and select Terminal Bus. You should see all your stations listed. If your target station is not listed or has a red cross icon, it means your network connection is not working.
Check the Windows user account settings
You can use two methods to check the Windows user account settings: the Control Panel and the Computer Management.
Open Control Panel on your ES and go to User Accounts. Make sure that your username and password are correct and that you have administrator rights. Also make sure that the guest account is enabled and has a password.
Open Computer Management on your ES and go to Local Users and Groups. Make sure that your username and password are correct and that you belong to the Administrators group. Also make sure that the guest account is enabled and has a password.
Check the network access rights
You can use two ways to check the network access rights: the Windows Explorer and the SIMATIC Shell tool.
Open Windows Explorer on your ES and go to Network. You should see your target station listed. Double-click on it and enter your username and password if prompted. You should see a folder named "SIMATIC" or "PCS7". Right-click on it and select Properties. Go to Sharing and make sure that the share name is correct and that you have full control permission. Go to Security and make sure that you have full control permission as well.
Open SIMATIC Shell on your ES and select Terminal Bus. Right-click on your target station and select Properties. Go to Download OS and make sure that the path to the target station folder is correct and that you have read/write access.
