Creating users 

The SecurityAdmin can only configure the system. All other activities must be performed by other users with other roles. You need at least a Security Auditor to access the security notifications, an Engineer to program in PLCnext Engineer and an Operator to operate an HMI. Below you will see how to add these users with their specific roles.

 For more information on the different users, roles and rights, refer to the User Authentication topic in the main PLCnext Technology ‑ Info Center.

 

For the following procedures you need access to the Web-based Management on the PLCnext Control.

System Use Notification

The system use notification is displayed each time a user wants to log on to the controller. The system use notification is independent of the language of the user interface in WBM and PLCnext Engineer. You should therefore take all required languages into account when editing.

To edit the system use notification, proceed as follows:

• Click the Edit Notification button.
  

An input window opens.

• Edit the System Use Notification.
  
• Confirm the entry by clicking the Save button.

The text is then transferred to the controller and stored.

To add a Security Auditor, proceed as follows:

• Log in to the WBM.
• Open the Security → User Authentication page in the WBM.

• Click the Add button. 
• In the added row SecurityAuditor, click the Edit User button.

Changing the password

Adding more users

If necessary, set up additional users. The number and the roles of the respective users depend on your system and the respective application.

Local user management

You can set up the users locally.

However, a global user management via LDAP is possible. When working with multiple devices (more than 3), Phoenix Contact suggests a global, network-based user management via active directory server (LDAP).

 For more information on LDAP, refer to the LDAP connection - file-based configuration topic in the main PLCnext Technology ‑ Info Center.

Information about the Admin

Even if the Security Profile is enabled, the Admin is allowed to make changes via SSH, e.g. the Netload Limiter configuration or the VPN configuration. For the commissioning phase it is possible to configure the Admin to make changes to PLCnext Technology configuration files. Afterwards the Admin must be deleted again in the User Manager!
 

Unauthenticated access

More accesses are possible via the Admin. This can disrupt production and reduce security. 

Do not start any plant with activated Admin!

 

With the Admin user, you can also use SSH to check the NTP connection. To do this, you must enable SSH in the firewall basic configurations (for more information, refer to the firewall basic configurations) and set an input rule:

Basic Configuration:

Input Rule:

 

Using the console, you can now check whether the connection has been established by using the ntpq -p command.

 

Checking password validity in the WBM

• Log in to the WBM. 

Return to topicHow do I get to the WBM again? Click here for more information... 

• Open the Cockpit page (Diagnostics → Cockpit) in the WBM. 

Based on the messages, you can check whether the passwords are still valid and whether a user has already changed his default password.
