CENTRUM = Fronius Central User Management

CENTRUM is a server-based application that centrally manages the user settings of several connected welding systems in a database.
The hardware or VM configuration required for this depends on the number of devices to be managed.
The user is responsible for the operation of the hardware or VM, and for the configuration, licensing, and maintenance of the recommended operating system.

It is not intended for CENTRUM to be installed and operated on a single desktop computer or system PC, for example in a production hall.

To ensure smooth operation, the setup of the server (hardware or VM), the design of the network infrastructure, and administration should only be performed by the user's IT department.

• the connection to Central User Management
• the configuration and management of the welding systems

Ensure proper firewall and network configuration for incoming and outgoing data traffic.

Connection from the welding systems to CENTRUM:

Connection from the user PC to CENTRUM:

IMPORTANT! For functional and security reasons, use the latest versions of the recommended browsers.

To start the Central User Management server, you must first create a container for Central User Management.

The container uses a defined Docker volume. The Docker volume is required in order to save the database independently of the container and thus enable server updates to be carried out without any loss of data.

The container uses a HTTPS connection in order to ensure the highest possible level of security during communication between the server and user.

In order to use HTTPS, copy the PFX or P12 certificate into the container as described below:

Run all of the following commands in the Shell of the operating system.

Explanation of the command:

<https-port>
The Port via which the Website of Central User Management can be accessed - always select Port 443, as this Port is stored on the welding systems and cannot be changed from there

-p 4711:4711
Port mapping that is required for connecting to the welding systems

-v centrum-data:<Container-Data-Folder-Path>
The Docker volume where the data are stored.

<Container-Data-Folder-Path> is the path for the storage data folder of the Central User Management server.

Linux container: /data
Windows container: C:\data

In this example, the Docker volume is named "centrum-data".

If a Windows container is used, in addition to the volume specification, the user must be specified as the ContainerAdministrator in the "create" command:
--user ContainerAdministrator

<Certificate-Password>
The password for the PFX or P12 certificate

<Certificate-Path-In-Container>
The path for the certificate in the container

Windows does not store certificates in a folder, which is why the path can be freely selected in Windows. For example:
C:\publish\Certificate.pfx

For Linux the following path is recommended:
/etc/ssl/private/Certificate.pfx

The browser can now be used to access Central User Management.

Prerequisite:
The power source of the welding system must be connected to a computer via network cable or integrated in a network.

1Enter the IP address of the desired power source into the browser, open SmartManager and log in

2Select the User Management tab

3Select the CENTRUM server tab

4In the input field highlighted, enter the domain name or the IP address of the server on which Central User Management has been installed (if using a domain name, a valid DNS server must be configured in the network settings of the power source)

5Check the box highlighted

6Click on the highlighted button

The availability of the specified server is checked.
If the specified server is available, "Server verified" appears.

7Save the changes

The power source is displayed in Central User Management.

8Integrate all subsequent power sources into Central User Management in the same way

A power source can also be connected to the CENTRUM server via the control panel.

1 Select "Defaults"

2Select "Administration"

3Select CENTRUM Server

4Activate CENTRUM Server

5Enter the CENTRUM Server

6Verify CENTRUM

7Save
