• Connection of non-HSR-enabled terminal equipment to ring-shaped networks, and non-PRP-enabled terminal equipment to parallel, separate networks
• Transition from ring-shaped HSR networks to parallel PRP network structures with HSR and combination unit
• Parallel data transmission by means of duplicate transmission in the ring network, or via two parallel separate networks
• Uncrossed connecting cables can be used due to Autocrossover function integrated in the ports
• Easy diagnostics using signaling contact, SNMP and Web browser
• Fast device replacement in the event of a fault by using the optional C-PLUG swap medium (not included in scope of supply)

Network topology and network configuration

The SCALANCE X-200RNA switches with IP20 degree of protection are usually installed in a control cabinet together with the stations to be connected. They can be mixed electrically and optically in star and line topologies.

When configuring the network, it is necessary to observe the following boundary conditions:

• Length of the TP cable between the network and SCALANCE X-200RNA:
  • Max. 100 m with IE FC cable and IE FC RJ45 Plug 180
  • Max. 10 m using patches with TP cord
• Length of the optical cables between the network and SCALANCE X-200RNA
  • Max. 5000 m with Industrial Ethernet glass fiber-optic cables (multimode)
  • Max. 26000 m with Industrial Ethernet glass fiber-optic cables (singlemode)
• IP address:
  The IP address is assigned by means of the DHCP (Dynamic Host Configuration Protocol). If there is no corresponding server in the network, the IP address can be assigned using the supplied software tool PST (Primary Setup Tool).

Commissioning and diagnostics

The SCALANCE X-200RNA Industrial Ethernet network access points can be integrated into a network management system via the standardized protocol SNMP (Simple Network Management Protocol). In the event of a fault in the device, error messages (SNMP traps) can be sent to a network system or as e-mail to a specified network administrator.

The integral Web server enables configuration and diagnostics settings to be made using a standard browser (e.g. port configuration). Statistical information can also be read out over the Web server (e.g. port capacity utilization).

The following information is displayed on site by LEDs:

• Power
• Port status
• Data traffic
• Signaling contact
• HSR activity

The SCALANCE X-200RNA Industrial Ethernet network access points can also be monitored using the floating signaling contact.
