• Construction of electrical and optical (XF-200BA IRT) Industrial Ethernet line, star and ring topologies
• Integral redundancy manager for setting up ring topologies
• Integral standby function for redundant coupling of two rings
• Extremely short cycle times with highly accurate clock-pulse rates thanks to integrated real-time functions
• Bumpless ring redundancy by sending frames twice in the ring, by means of PROFINET-compliant MRPD procedure (media redundancy for planned duplication according to IEC 61158)
• Isochronous mode applications up to 250 µs and jitter of less than 1 µs
• Load disconnection through integrated switch functionality
• Easy diagnostics using signaling contact, SNMP and web browser
• Automatic email function
• Integration into the diagnostics of a PROFINET IO Controller by means of real-time communication (RT) according to the PROFINET standard
• Fast device replacement in the event of a fault by using the optional C-PLUG removable data storage medium (not included in scope of supply)

Network topology and network configuration

The SCALANCE XF-200IRT and XF-200BA IRT Industrial Ethernet switches are typically accommodated together with the stations to be connected in one control cabinet. Electrical and optical versions (XF-200BA IRT) can be installed together in star, line and ring topologies.

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 and IE FC RJ45 Plug 180
• IP Address:
  The IP address is assigned using the DHCP (Dynamic Host Configuration Protocol) mechanism. 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. The device and real-time configuration of the SCALANCE XF204IRT switch is performed via STEP 7.

Commissioning and diagnostics

PROFINET diagnostic alarms from SCALANCE XF-200IRT and XF-200BA IRT switches can be displayed with the appropriate SIMATIC engineering tools and processed in the controller with the enhanced 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.

SCALANCE XF-200IRT and XF-200BA IRT Industrial Ethernet switches can also be integrated in a network management system such as SINEMA server using 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 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).
