Overview

CitectSCADA has two types of project:

Read-write: allows write and delete privileges to the project folder (or for any project file) for the current user.
Read-only: projects that deny write and delete privileges to the project folder for the current user.

The table below shows the different characteristics of read-only and read-write projects:

Task	Read-only	Read-write
View existing files in project	x	x
Create new files in project		x
Delete existing files in project		x
Modify existing files in project		x
Delete project		x
Rename project directly		x

Read-only projects cannot be compiled as top-level projects (i.e., projects that are the main (root) project as opposed to an included project) and online changes are not supported.

Note: If the project folder is read-only for the current user, but one or more files in the project have read-write access for the current user, the project is considered to be a hybrid read-only/read-write project. CitectSCADA does not support this type of project. Running a hybrid project may result in your system becoming unresponsive. (This note does not include those folders or files that require read-write access in order to operate at runtime; see Using CitectSCADA with Windows Security for details.)

The security model used in enabling read-only projects does not replace the existing CitectSCADA user accounts; instead, it works in conjunction with user accounts like this:

CitectSCADA user accounts govern runtime security to project elements.
Windows user accounts govern the security of configuration project elements.
