Can I make some of my points Read-only for specific users and Read/Write to other users?

Yes, the Sinolta security system allows you to set up your system so specific users can have No Visibility, Read-only and Read/Write access levels for different points in the system.
The security model is controlled through Security Groups. You first have to define the User Group security level and then assign each user to one or multiple User Groups.
At the same time, each point has a user Access level parameter. By default, all users are set up to have Read/Write access level by all users.
Please consult Security Tutorial martial before you start changing your system security configuration.
