HMI projects folder
By default, SE and ME HMI server projects are stored in C:\Users\Public\Documents\RSView Enterprise\SE\HMI projects and C:\Users\Public\Documents\RSView Enterprise\ME\HMI projects on the HMI server computer. To enhance security and prevent unauthorized modifications to these projects, Windows administrators can use the HMI Projects Folder Path Config Utility to specify a new folder to hold SE and ME HMI projects where only users with permissions can access.
Whoever configures the new HMI projects folder is given full control to the folder. After the configuration, the folder inherits its parent folder's security, and its access is configured for these user groups:
- NT AUTHORITY\SYSTEM: Full control
- NT AUTHORITY\LOCAL SERVICE: Full control
- NT AUTHORITY\BATCH: All permissions except for two advanced ones "Change permissions" and "Take ownership"
- BUILTIN\Administrators: Full control
- NT AUTHORITY\SERVICE: All permissions except for two advanced ones "Change permissions" and "Take ownership"
Do not change these user groups or their accesses as listed above, which are necessary for FactoryTalk View to work properly. To give more users access to the HMI projects folder, you must grant them full control and ensure that the subfolders and files inherit these permissions.
TIP:
Be aware of a Windows behavior when configuring the folder security. That is if a folder's access is configured to the Administrators group only, this folder is read-only to users even though they are in the Administrators group. Make sure that the user itself has read and write permissions to the folder.
If you choose to use the default folder, Windows administrators can tighten the Windows folder's security settings on the HMI server computer by following these steps:
- Remove theINTERACTIVEgroup from the folder's security properties.
- Add specific users or user groups and assign their permissions to this folder as needed.
