Network topology and network configuration

Connection of a PROFINET MRP ring to S2 devices, for example to the redundant network topology of a SIMATIC AS 410H.

The SCALANCE XF204-2BA DNA Industrial Ethernet switch with IP20 degree of protection is installed in a control cabinet together with the nodes to be connected. Electrical and optical versions can be installed together in star, line and ring topologies on the device side.

When configuring the network, the following boundary conditions must be observed:

• Length of the TP cable between two SCALANCE XF switches:
  • Max. 100 m with IE FC cable
• IP address:
  The IP address is assigned by means of the DHCP (Dynamic Host Configuration Protocol). If there is no corresponding server available in the network, the IP address can be assigned using the supplied PST software tool (primary setup tool) or STEP 7. The SCALANCE XF204-2BA DNA switches are configured with STEP 7.

Commissioning and diagnostics

The PROFINET diagnostic interrupt of the SCALANCE XF204-2BA DNA can be displayed with the appropriate SIMATIC engineering tools and processed in the controller with the enhanced diagnostic function. The engineering effort for the PLC and HMI have been drastically reduced due to the complete integration in the SIMATIC concept for critical messages.

The SCALANCE XF204-2BA DNA Industrial Ethernet switch can be integrated into a network management system, e.g. SINEMA Server, through the standardized Simple Network Management Protocol (SNMP). In the event of a fault in the device, error messages (SNMP traps) can be sent to a network system or as email to a specified network administrator.

The integrated web server allows configuration and diagnostics settings, such as port configuration, using a standard browser. Statistical information, such as port utilization, can also be read out via the web server.
