:strong:Recommendations for data security
In order to minimize the risk of breaches of data security, we recommend the following organizational and technical measures for the system on which your applications run: As far as possible, avoid exposing the PLC and control networks to open networks and the Internet. For protection, use additional data link layers such as a VPN for remote access and install firewall mechanisms. Limit access to authorized persons, change any existing standard passwords during the initial commissioning and continue to change them regularly.
On this tab of the generic device editor you edit the ‘online user management’ of the control device.
Depending on how this is supported by the device, you can define user accounts and user groups. In combination with the configuration on the Access rights tab, you thus control access to control objects and files at runtime.
Requirement: the controller has a user management and you have login data in order to be able to log in to the controller.
In principle the handling of the dialog box Users and Groups is very similar to that of the project user management. There is even a possibility to ‘import’ user account definitions from the project user management.
All currently defined users, and below them their memberships of user groups, are listed in a tree structure. | |
![]() |
Opens the dialog box Add User. Define a new user name and a password. Confirm the password and create the new user account by clicking on OK. |
![]() |
Opens the dialog box Import User. It displays all the user accounts defined in the project user management. Select the desired entries and click on OK in order to import them into the device-specific user management. IMPORTANT: the passwords are NOT imported! |
![]() |
Opens the dialog box Edit User <user name>. It corresponds to the dialog box Add User and you can change the user account. |
![]() |
Deletes the account of the currently selected user. |
All currently defined groups, and below them the users assigned to them, are listed in a tree structure. | |
![]() |
Opens the dialog box Add group. Define a new group name. From the list of defined users, select those that are to belong to the group. Confirm the selection with OK. The group appears in the tree. |
![]() |
Opens the dialog box Import User. It displays all the user groups defined in the project user management. Select the desired entries and click on OK in order to import them into the device-specific user management. |
![]() |
Opens the dialog box Edit Group <group name>. It corresponds to the dialog box Add group and you can change the group definition. |
![]() |
Deletes the currently selected group. |

CODESYS loads the current configuration of the access rights to the controller in order to make it effective there. |
<setting> |
CODESYS fetches the current configuration of the access rights from the controller. |
Save to disk | CODESYS stores the current user configuration in an xml file of the type \*.dum . ‘dum’ means ‘Device User Management’. |
![]() |
CODESYS reads a rights configuration from an xml file of the type \*.dum . |
