Features:

• The RJ45 ports are designed to be industry-standard with additional holding collars for connecting the IE FC RJ45 Plug 180

Diagnostics access over SNMP and Web browser with SCALANCE X208

The SCALANCE X-200 Industrial Ethernet switches with a rugged metal housing are optimized for mounting on a standard rail and an S7-300 rail. Direct wall mounting in various positions is also possible. Thanks to the S7-300 housing dimensions, the devices are suitable for integration into an automation solution with S7-300 components.

The switches with IP20/IP30 degree of protection feature:

• A 4-pole terminal block for connecting the redundant supply voltage (2 x 24 V DC)
• A row of LEDs to indicate the status information (power, link status, data exchange, power supply, signaling contact)
• A 2-pole terminal block for connecting the floating signaling contact
• A SET button for on-site configuration of the signaling contact

The SCALANCE X-200 switches are available with the following port types:

• 10/100BaseTX, RJ45 connection;
  automatic detection of the data rate (10 or 100 Mbit/s), with autosensing and auto-crossover function for connecting IE FC cables via IE FC RJ45 Plug 180 over distances up to 100 m.

  BFOC ports for direct connection to Industrial Ethernet glass fiber-optic cables up to 5 km (multimode FOC) or up to 26 km (single-mode FOC) for configuring line, ring and star topologies.

Network topology and network configuration

The Industrial Ethernet SCALANCE X-200 switches with IP30 degree of protection are usually installed in a control cabinet together with the stations to be connected. Electrical and optical versions can be installed together in star, line and ring topologies.

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 RJ45 Plug 180
  • Max. 10 m using patches with TP cord
• Length of the optical cables
  • 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) or STEP 7.

Commissioning and diagnostics

PROFINET diagnostic interrupts from SCALANCE X 200 Switches can be displayed with the appropriate SIMATIC Engineering Tools and processed in the controller with expanded diagnostics 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-200 Industrial Ethernet switches can also be integrated into a network management system such as 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 Industrial Ethernet switches of the SCALANCE X-200 line can also be monitored using the floating signaling contact.
