User groups

In CoDeSys up to eight user groups with different access rights to the POUs, data types, visualizations, and resources can be set up. Access rights for single objects or all of them can be established. Only a member of a certain user group can open a project. A member of such a user group must identify himself by means of a password.

The user groups are numbered from 0 to 7, whereby the Group 0 has the administrator rights, i.e. only members of group 0 may determine passwords and access rights for all groups and/or objects.

When a new project is launched, then all passwords are initially empty. Until a password has been set for the 0 group, one enters the project automatically as a member of the 0 group.

If a password for the user group 0 is existing while the project is loaded, then a password will be demanded for all groups when the project is opened.

In the combobox User group on the left side of the dialog box, enter the group to which you belong and enter on the right side the relevant password. Press OK. If the password does not agree with the saved password, then the message appears: “The password is not correct.”

Only when you have entered the correct password the project can be opened. With the command ‘Passwords for user group’ you can assign the passwords, and with ‘Object’ ‘Access rights’ you can define the rights for single objects or for all of them.
