• Integrated redundancy manager for constructing Fast Ethernet and Gigabit Ethernet ring topologies with high-speed media redundancy. Reliable communication is achieved by closing an optical or electrical line with SCALANCE XR-500, XM-400, XC-300 or XC-200 switches to form a ring. The redundancy manager (RM) integrated in the SCALANCE X-/XR-300 switch monitors the function of the network. It recognizes the failure of a transmission link or of SCALANCE X switch in the ring and activates the substitute path within a maximum of 0.2 seconds.
• Redundant connection to corporate networks;
  SCALANCE X-/XR-300 switches support the Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP) standardized redundancy procedures. This enables a subnetwork to be connected redundantly to a higher-level corporate network with reduced requirements for the reconfiguration time (in the order of seconds). By supporting the Multiple Spanning Tree Protocol (MSTP), a network can also be split into multiple sub-segments.
• Support of virtual networks (VLAN);
  for structuring Industrial Ethernet networks with a fast-growing number of nodes, a physically existing network can be divided into several virtual subnetworks.
• Load limiting when multicast protocols (e.g. video transmission) are used;
  through learning the multicast sources and targets (IGMP Snooping, IGMP Querier), SCALANCE X-/XR-300 switches can also filter multicast data traffic and therefore limit the load in the network. Multicast and broadcast traffic can be limited.
• Time synchronization;
  diagnostic messages (log table entries, emails) are time-stamped. The local time is standardized throughout the network by means of synchronization with a SICLOCK time transmitter, SNTP or NTP server or via IEEE1588, thereby simplifying the assignment of diagnostic messages of several devices.
• Fast replacement of devices in the event of a fault by using the C-PLUG removable data storage medium
• Link aggregation (IEEE 802.1q) for bundling data streams
• Quality of Service (IEEE 802.1p) for prioritization of network traffic
• SCALANCE X308-2M PoE, XR324-4M PoE, XR324-4M PoE TS: Support of Power over Ethernet (PoE) according to IEEE 802.3at Type 1 (corresponds to IEEE 802.3af)
• Increase of the network performance;
  by filtering the data traffic on the basis of the Ethernet (MAC) address of the terminal devices, data traffic remains local; only data intended for users of another subnetwork is forwarded by the switch.
• Simple network configuration and network expansion;
  the switch saves the data received at the ports and forwards it automatically to the destination address. Collision detection (CSMA/CD method) does not restrict the expansion of the network beyond the port.
• Limitation of the error propagation to the affected subnetwork;
  the SCALANCE X-/XR-300 switches only forward data with a valid checksum (CRC).
• Integration of existing subnetworks with 10 Mbps into Fast Ethernet networks with 100 Mbps;
  at the twisted pair ports, the SCALANCE X-/XR-300 switches automatically recognize the conductor pairs for transmission and reception (autocrossover), the data transmission rate of 10 or 100 or 1000 Mbps, as well as full-duplex or half-duplex mode (autonegotiation).
• High-performance connection of SCALANCE X-300 switches with 1 Gbps;
  SCALANCE X-/XR-300 switches have Gigabit Ethernet ports for connecting the switches to each other or with other Gigabit Ethernet-enabled components (e.g. SCALANCE XC-200, XM-400, XR-500).
• High-speed standby redundancy;
  several network segments such as rings can be interconnected redundantly with SCALANCE X-/XR-300 by means of the integrated standby function. Two SCALANCE X/XR-300 switches configured in one ring as a polling system are connected to the other ring via two links. The redundant coupling can be implemented at 1000 Mbps.
• Configuration of the ports for terminal devices that support authentication in accordance with IEEE 802.1X. Authentication is by means of a RADIUS server that must be configured appropriately and must be accessible via the network.
• Support of the DHCP Option 82, 66, 67 (Dynamic Host Configuration Protocol);
  this permits the IP address assignment of a terminal device depending on the connected Switch Port. The IP address assignment is by means of a DHCP server that must be configured appropriately and must be accessible via the network.
• Support from the Access Control List (ACL);
  if this function is activated for one port, the switch forwards the message frames received to this port if its source address is present in the address table. All connected nodes can be automatically entered in the ACL.
• Syslog;
  Syslog compliant with RFC 3164 is used in the IP network for transmitting short, unencrypted text messages via UDP. This requires the use of a Syslog server that must be configured appropriately and must be accessible via the network.
• Time synchronization;
  diagnostic messages (log table entries, emails) are time-stamped. The local time is standardized throughout the network by means of synchronization with a SICLOCK time transmitter, SNTP or NTP server or via IEEE1855.

Network topology and network configuration

The network topology can easily be adapted to the structure of the plant using SCALANCE X-/XR-300 Industrial Ethernet switches. The SCALANCE X-/XR-300 Industrial Ethernet 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.

The following network structures and combinations of structures can be implemented:

• Fast Ethernet with fast media redundancy;
  To increase network availability, as many as 50 linear cascaded XC-200, XC-300, XM-400 or XR-500 switches be configured into a ring.
• Several rings can be redundantly linked through the standby function
• At the same time, SCALANCE X-/XR-300 supports redundant connection of the ring structure to the corporate network with a Rapid Spanning Tree.
• Star topology with SCALANCE X-/XR-300 switches:
  Each SCALANCE XR-300 switch represents a neutral point that can connect up to 24 nodes or subnets with each other.

Commissioning and diagnostics

Setting options on the device itself:

• Redundancy manager RM;
  To establish a ring, a SCALANCE X-/XR-300 is switched to the RM mode. The Gigabit ports (electrical or optical) are preferably used as ring ports. The non-ring ports of the RM can be used freely for the connection of terminal devices and networks. If the MRP redundancy procedure standardized by PROFINET is used, the RM is adjusted automatically.
• Signal mask;
  The signal mask is set to the current status of the SCALANCE X-/XR-300 (setpoint state) by pushbutton operation. The signal mask defines which ports and which power supplies are to be monitored. The signaling contact only reports an error when a monitored port or a monitored feeder fails (deviation of setpoint/actual status).
• IP address;
  the IP address is assigned via DHCP (Dynamic Host Configuration Protocol). If there is no corresponding server in the network, the IP address can be assigned using the software tool provided.

Diagnostic options on site:

• The following status information is displayed by LEDs on site:
  • Port status
  • Port mode (10/100/1000 Mbps, full/half-duplex)
  • Status of the two power supplies
  • Signaling contact status
  • Signal mask (setpoint status)
  • RM mode
  • Standby mode
• The status of the signaling contact is routed externally by means of floating relay contacts. This enables, for example, the module to be monitored via an input module from a controller.
• Monitoring via the Industrial Ethernet network;
  the following options are available:
  • Remote via standard browser (web-based management):
    Selection of SCALANCE X-/XR-300 switches via the network from a PC with web browser
  • Remote via SNMP V1, V2c, V3:
    Secure integration of SCALANCE X-/XR-300 switches via the network into a network management system, e.g. SINEC NMS
  • Remote via PROFINET diagnostics:
    PROFINET diagnostic interrupts from SCALANCE X-/XR-300 switches can be displayed with the appropriate SIMATIC engineering tools and processed in the PLC. The engineering outlay for the PLC and HMI has been drastically reduced due to the complete integration in the SIMATIC concept for system error messages.

Network management

The network management provides the following functions:

• Password-protected dial-up for “Administrator” (read and write authorization) and “User” (read only)
• Read-out of version and status information
• Setting the signal and standby mask and address information
• Fixed parameterization of the ports (data transmission rates, half/full duplex) and filter tables
• Setting parameters of the VLANs and multicast services
• Parameterization of the standby connections for a redundant ring connection
• Setting of Spanning/Rapid Spanning Tree parameters
• Parameter assignment for web management services
• Security
  • Ports can be connected or disconnected
  • Port-based network access control according to IEEE 802.1X
  • Authentication in accordance with IEEE 802.1x
  • Support of Access Control List (ACL)
• Parameter assignment for user administration of SNMP V1, V2c, V3
• Output of statistics information
• Diagnostics of data traffic by means of a parameterizable mirror port with a standard commercial network analyzer (e.g. via Bus Analyzer Agent XM-400)
• Loading of new firmware versions or configuration data via the network from a TFTP server or directly via email/HTTPS with a web browser
• Saving of configuration data or log table via the network on a TFTP server

If faults occur in the network, the SCALANCE X-/XR-300 switch can independently send error messages (traps) to a network management system (e.g. SINEC NMS) or emails to a specified network administrator.

Remote monitoring (RMON) provides the following functions:
The SCALANCE X-/XR-300 can collect statistics information according to the RMON groups 1 to 4. These include, for example, fault statistics that are kept for each port. This information can be read out through web-based management in the statistics sub-area.
