• Configuration of electrical Industrial Ethernet line, star and ring topologies
• Fast redundancy in the ring with
  • High Speed Redundancy Protocol (HRP); up to 0.3 seconds for reconfiguration of the ring with 50 switches in the ring
  • PROFINET MRP (Media Redundancy Protocol); up to 0.2 seconds for reconfiguration of the ring with 50 switches in the ring
• The functioning of the ring is continuously monitored by the integrated redundancy manager. It recognizes failure of a transmission path in the ring or failure of a SCALANCE X-200 and activates the substitute path within 0.3 seconds or 0.2 seconds with MRP
• Use in ring topologies (100 Mbit/s) together with SCALANCE X-300, SCALANCE X-400 and SCALANCE X-500
• Uncrossed connecting cables can be used due to Autocrossover function integrated in the ports
• Easy diagnostics using signaling contact, SNMP and Web browser
• Easy copper cable diagnostics with Web browser for localizing cable breaks
• Easy fiber-optic cable port diagnostics by means of Web browser and SNMP for early detection of changes on the fiber-optic cable line or at the fiber-optic cable ports
• Integration into the diagnostics of a PROFINET I/O controller with expanded diagnostics functions for a consistent diagnostics concept, including network infrastructure
• Diagnosis of data traffic by means of a parameterizable mirror port with a standard commercial network analyzer
• Optimized support of PROFINET real-time communication (RT) through prioritizing
• 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 X208PRO Industrial Ethernet switch is designed for installation outside the control cabinet.

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

• Length of the TP cable between two SCALANCE X switches:
  • Max. 100 m with IE FC cable and IE FC M12 Plug PRO
  • Max. 10 m using patches with TP cord
• 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) or STEP 7.

Commissioning and diagnostics

PROFINET diagnostic interrupts from the SCALANCE X-208 PRO switch can be displayed with the appropriate SIMATIC Engineering Tools and processed in the controller with an expanded diagnostic function. The engineering outlay for the PLC and HMI have been drastically reduced due to the complete integration in the SIMATIC concept for system error messages.

The SCALANCE X-208 PRO Industrial Ethernet switch can also be integrated into a network management system, e.g. SINEMA Server, through the standardized Simple Network Management Protocol (SNMP). If faults occur on the device, error messages (SNMP traps) can be sent to a network management 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
• Redundancy manager function

The SCALANCE X-208 PRO Industrial Ethernet switch can also be monitored using the floating signaling contact.
