Ports 1 and 2 are the RJ45 connectors of Ethernet module 1. Ports 3 and 4 are the RJ45 connectors of Ethernet module 2. Port 5 is the RJ45 connector of the onboard standard Ethernet port. The +24 V connector provides the +24 V power supply voltage for the board. January 2019 Support of the DS6335-CS Ethernet Board 9

10 Description of the DS6335-CS Ethernet Board The CompactPCI Serial connector is used to connect the board to the DS6001 Processor Board via the backplane of the SCALEXIO LabBox. The RJ45 connectors' shield conductors are internally connected to the earth ground (and the system's enclosure). Slot dependency and installation The board requires one slot with PCIe support in a SCALEXIO LabBox. You can use up to five Ethernet boards (DS6333-CS and DS6335-CS) in a SCALEXIO LabBox. It is recommended to use the slots with PCIe x4 support first. When you work at very high data rates and use all controllers, slots with PCIe x1 support might not support full Ethernet speed.) To install the board in a SCALEXIO LabBox, refer to How to Install a Board into SCALEXIO LabBox ( SCALEXIO Hardware and Software Overview). Safety precautions for LAN connections Observe the following safety precautions when establishing a physical Ethernet (LAN) connection. NOTICE All the local area network (LAN) ports of a SCALEXIO system contain safety extra low voltage (SELV) circuits, which must be connected only to other SELV circuits. To avoid electric shock, do not connect the LAN ports of a SCALEXIO system to non SELV circuits, e.g., telecommunication network voltage (TNV) circuits. The LAN or LAN segment of a SCALEXIO system and all connected equipment must be part of the same low voltage power distribution system and be located within a single building. Do not use RJ45 connectors of wide area network (WAN) ports, because WAN ports can contain TNV circuits. When connecting external devices, e.g., an ECU, to the LAN ports of a SCALEXIO system, keep in mind that the LAN ports' shield conductors are galvanically connected to the earth ground (protective earth) of the SCALEXIO system. To avoid a fire caused by overheated wiring due to excessive current flow in the shield conductor, do not connect LAN shield conductors to ECU housings, ECU grounds, or the signal ground of the SCALEXIO system. LAN cables can occasionally be subject to hazardous transient voltages, such as lightning or disturbances in the electrical utilities power grid. Handle exposed metal components of the network with caution. Do not connect the RJ45 connectors of a DS6330M1 Automotive Ethernet Module with a standard Ethernet network. 10 Support of the DS6335-CS Ethernet Board January 2019

18 Configuring the Board via the SCALEXIO Web Interface Web Interface for Configuring the SCALEXIO System Introduction The board can be configured via the web interface of the DS6001 Processor Board of the SCALEXIO system. You can open the web interface in any Internet browser. Basics on the web interface The following illustration shows the start page of the web interface: You can access the web interface by typing the SCALEXIO system's IP address in the address bar of an Internet browser. By default, the Ethernet port for the host PC connection of SCALEXIO processing hardware is preconfigured as follows: IP address: Network mask: Support of the DS6335-CS Ethernet Board January 2019

19 Ethernet Switch Configuration Page Ethernet Switch Configuration page If the SCALEXIO system includes one or more DS6333-CS or DS6335-CS boards, you can configure the boards on the Ethernet Switch Configuration page. Ethernet Switch Configuration Page Introduction The Ethernet Switch Configuration page lets you specify and manage the Ethernet switch and PHY configuration of DS6333-CS Automotive Ethernet Boards and DS6335-CS Ethernet Boards which are installed in a SCALEXIO LabBox that has a DS6001 Processor Board. Basics on the Ethernet switch configuration The Ethernet switch configuration comprises the configuration of the board's physical layers (PHYs) and the Ethernet switch. The Ethernet switch configuration is stored on the related SCALEXIO processing hardware. States of the Ethernet configuration Initially, when a SCALEXIO system is powering up, all PHYs of an Ethernet board are deactivated and the Ethernet communication between any switch ports is disabled. As soon as the SCALEXIO system has booted, the Ethernet switch configuration is used to configure the board's PHYs and the Ethernet switch. This configuration is valid until you switch off the SCALEXIO system. January 2019 Support of the DS6335-CS Ethernet Board 19

20 Configuring the Board via the SCALEXIO Web Interface Slot-specific and board-specific Ethernet switch configuration You can specify the Ethernet switch configuration as slot-specific or board-specific, which depends on the name you assign to the configuration: By default, the Ethernet switch configuration is slot-specific. This is indicated by a name of the type SwitchX_Y, where X is the number of the board's PCIe slot and Y the number of the board's Ethernet switch. If you install another Ethernet board in the slot, the board is also operated with this slot-specific Ethernet switch configuration. If one or both DS6330Mx modules of the new board differ from the original installation, the default configuration for the related module is used. If you specify an individual name for the Ethernet switch configuration, the configuration is board-specific. If you change the board's slot, the board is identified by its serial number and keeps its individual configuration of the Ethernet switch and the physical layers permanently. The configuration is stored on the DS6001 Processor Board. If you install the Ethernet board in another SCALEXIO LabBox, you must repeat the Ethernet switch configuration for the related processing board. If you change a DS6330Mx module on the board to a new type, the new module is configured with the default configuration for its physical layers. Identification properties Name Lets you select an Ethernet switch configuration. Switch configuration configuration: Slot-specific Or Board-specific Displays the type of the selected Ethernet switch Board type Board slot Displays the board type of the related Ethernet board. Displays the board's PCIe slot number. Note The board's I/O slot number differs from the PCIe slot number that is used to generate the configuration's default name SwitchX_Y. (In a SCALEXIO LabBox, the I/O slot numbers 3 7 correspond to the PCIe slot numbers 1 5.) Board serial number board. Displays the serial number of the related Ethernet Switch configuration properties Lets you specify a name for the Ethernet switch with a case- Switch name sensitive string. If you use the default name SwitchX_Y, the configuration is used as a slotspecific configuration. If you specify an individual name, the configuration is used as a board-specific configuration. To delete the board-specific configuration, change the name to the default name SwitchX_Y. 20 Support of the DS6335-CS Ethernet Board January 2019

21 Ethernet Switch Configuration Page Start with power-up configuration All PHYs are deactivated and communication between any switch ports is disabled. Use switch in unmanaged mode This option lets you enable communication between any switch ports. All PHYs are activated. Refer to the following illustration.

22 Configuring the Board via the SCALEXIO Web Interface Physical layer configuration properties The web interface displays information on the module type and port number. The configurable physical layer properties depend on the used port and the installed modules. Automotive Ethernet module For each port of a DS6330M1 Automotive Ethernet Module, you can specify the following properties: Power enabled or Power disabled to switch on or off the PHYs. 100 Mbps/full-duplex or 1000 Mbps/full-duplex to specify the data rate and the duplex mode. Master or Slave to specify the port as master or slave port. The default settings are: Power enabled, 100 Mbps/full-duplex, and Master. Standard Ethernet module For each port of a DS6330M2 Ethernet Module, you can specify the following properties: Power enabled or Power disabled to switch on or off the PHYs. 10 Mbps/full-duplex, 10 Mbps/half-duplex, 100 Mbps/full-duplex, 100 Mbps/half-duplex, 1000 Mbps/full-duplex, or Auto Negotiation to specify the data rate and the duplex mode. The default settings are: Power enabled and Auto Negotiation.

26 Using Ethernet Boards in ConfigurationDesk Overview of Ports and Properties (Ethernet Setup) Overview illustration The following illustration shows the ports and the basic properties of the function block. The illustration shows the properties which support the basic functionality of the function block, and the properties which influence whether specific ports and other properties are available. Ethernet Setup Internet protocol IPv6 IPv4 Local IP address Subnet mask Subnet prefix length Feature activator Default gateway Default gateway Optimization Address resolution method Ports The Ethernet Setup function block does not provide signal ports or function ports. Tunable parameters The Ethernet Setup function block does not provide tunable parameters. Configuring the Basic Functionality (Ethernet Setup) Overview The function block type provides the following configuration features which influence the behavior of the basic functionality: Specifying the local IP address Specifying the default gateway Optimizing the Ethernet adapter Specifying the address resolution method Assigning an Ethernet adapter 26 Support of the DS6335-CS Ethernet Board January 2019

27 Ethernet Setup Function Block Specifying the local IP address With the local IP address, you specify two parts for IP networking: You specify a unique IP address for the assigned Ethernet adapter. You specify the subnetwork the Ethernet adapter is connected to via the netmask (subnet mask/subnet prefix length). The netmask determines the most significant bits of the local IP address as the subnetwork address, the least significant bits determine the host address. The subnetwork address indicates the members of the same subnetwork. That means, all members must use the same Internet Protocol version, subnetwork address, and subnet mask or subnet prefix length. The members differ only in the host address. Tip If an external Ethernet devices is already configured, use the subnet mask/subnet prefix length of the configured device and the resulting subnetwork address. For example: An external Ethernet device uses the IP address and the subnet mask The resulting IP address range for the local IP address is with the subnet mask ( and are reserved IP addresses). Workflow to specify the local IP address you have to proceed in the following order: To specify the local IP address, 1. Select the IPv4 or IPv6 Internet protocol version for IP network communication. IPv4 addresses are 32 bit addresses that are commonly represented by four groups written in decimal numbers, such as IPv6 addresses are 128 bit addresses that are commonly represented by up to eight groups with hexadecimal numbers, such as 2001:db8:74b2:fa50:1:cb3e: 375: Specify a unique IP address for the assigned Ethernet adapter. For recommended IP addresses, refer to Recommended IP address ranges on page 28. Note Multicast IP addresses cannot be used to specify the local IP address and the use of reserved IP addresses is not recommended. 3. Specify how many most significant bits of the IP address are used to specify the subnetwork address. This is done via the subnet mask for IPv4 addresses or the subnet prefix length for IPv6 addresses. January 2019 Support of the DS6335-CS Ethernet Board 27

28 Using Ethernet Boards in ConfigurationDesk Recommended IP address ranges The following table shows you the recommended IP address ranges for specifying the local IP address: IPv4 IPv fc00::1... fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff Unfavorable IP address ranges The following IP address ranges are not recommended to be used as the local IP address: The first IP address of the subnetwork if all bits of the host part are set to 0. For example: with the subnet mask IPv4 Broadcast addresses: The last IP address of the subnetwork if all bits of the host part are set to 1. For example: with the subnet mask Loopback addresses: (IPv4) and ::1 (IPv6) Using DHCP The Ethernet Setup function block does not support DHCP. Specifying the default gateway A default gateway lets you send IP packets outside the local subnetwork that you specified via the subnet mask/subnet prefix length and the local IP address. The default gateway to other networks can be the router of your network. To make the default gateway known to the Ethernet adapter, you have to activate the default gateway feature via the Feature activator property and enter the IP address of the default gateway. The default gateway must be a member of the same subnetwork as the assigned Ethernet adapter. If you use a default gateway, IP packets with IP addresses of other networks are sent to the default gateway. Then, the default gateway manages the next transport steps. Optimizing the Ethernet adapter Depending on the use case, you can optimize the handling of data sets with the Optimization property. You can select the following modes: Latency Select this mode if the reaction time is crucial for your application, e.g., for application with Ethernet triggered task. In this mode, the Ethernet adapter is more responsive to packet handling. However, the Latency mode causes more processor load than the Throughput mode. Throughput Select this mode to optimize the throughput of large data sets. 28 Support of the DS6335-CS Ethernet Board January 2019

29 Ethernet Setup Function Block Note If the Ethernet Setup block is referenced by one or more ECU Interface Configuration function blocks, the setting of the Optimization property is ignored for code generation. Instead, the optimization mode specified in the imported ECU interface container is used. However, the setting of the Optimization property is used for code generation if the function block is referenced by two or more ECU Interface Configuration function blocks with different settings for the optimization mode (imported via the ECU interface container). In this case, ConfigurationDesk generates a conflict. Specifying the address resolution method You can specify the address resolution method that the Ethernet interface uses to map the IP address to a MAC address: ARP/RFC826 The Ethernet adapter uses the address resolution protocol (ARP) according to IETF RFC 826 to resolve the MAC addresses of the network members. ARP is the common protocol for address resolution in Ethernet networks. Learn MAC from multicast messages This method is intended for Ethernet networks that try to avoid ARP requests. Note Learn MAC from multicast messages is reserved for future use. Assigning an Ethernet adapter You have to assign an Ethernet adapter that is part of your SCALEXIO system, e.g., the Ethernet adapter of the SCALEXIO Processing Unit. The Ethernet Setup function block supports the following channel types: Ethernet Adapter 1 Available on the SCALEXIO Processing Unit providing one Ethernet adapter (controller). Available on the DS6001 Processor Board providing one Ethernet adapter (controller). Available on the DS6331-PE Ethernet Board providing four Ethernet adapters (controllers). Ethernet Adapter 2 Available on the DS6333-CS Automotive Ethernet Board providing four Ethernet adapters (controllers). Available on the DS6333-PE Automotive Ethernet Board providing four Ethernet adapters (controllers). Available on the DS6335-CS Ethernet Board providing four Ethernet adapters (controllers). Ethernet Adapter 1 The Ethernet adapter of the Ethernet Adapter 1 channel type is directly connected to one RJ45 connector. January 2019 Support of the DS6335-CS Ethernet Board 29

32 Using Ethernet Boards in ConfigurationDesk Virtual Ethernet Setup Function Block Function block purpose With the Virtual Ethernet Setup function block type, you can configure a virtual Ethernet adapter to access an Ethernet network, including VLAN. The function block works as a provider: Other function blocks can use it to access the configured Ethernet adapter. Block overview The function block provides neither signal ports nor function ports. The illustration below shows the function block with its default settings.

For example, you can add a virtual Ethernet adapter to your Ethernet network to provide additional IP configurations for a physical Ethernet adapter. Several virtual Ethernet adapters can use the same physical Ethernet adapter. 32 Support of the DS6335-CS Ethernet Board January 2019

VLANs let you manage the LAN independently of the physical network. Basics on virtual Ethernet adapter Virtual Ethernet adapters have their own local IP addresses and netmasks. For the electrical connection to the Ethernet network, they use physical Ethernet adapters. The MAC addresses of the virtual Ethernet adapters can be specified as follows: You can use the MAC address of the used physical Ethernet adapter. This configuration is called IP aliasing because several IP addresses belong to the same MAC address. You can specify custom MAC addresses. For other Ethernet devices, a virtual Ethernet adapter with a custom MAC addresses does not differ from physical Ethernet adapters. You can also specify alias IP addresses for one custom MAC address. Benefits of virtual Ethernet adapters adapters has the following benefits: The virtualization of Ethernet You can provide different IP addresses for different services on the same physical Ethernet adapter. For example, you can provide a virtual IP address to provide diagnostic information and a virtual IP address to control systems for driver safety.

The VLAN tag includes an identity number to identify the members of the same VLAN. Ethernet devices of the data link layer, such as Ethernet switches, read the VLAN tag and route the Ethernet frames between the members of the same VLAN: Ethernet frames are forwarded only within the same VLAN. This means, even if an Ethernet device is a member of the same IP subnetwork as another Ethernet device, it cannot transmit or receive data if the Ethernet devices are in different VLANs. Multicast and broadcast messages are sent only to the members of the same VLAN. A VLAN is independent from IP networking. One VLAN can cover several IP subnetworks or only a part of an IP subnetwork. For more information on the VLAN tag, refer to Basics on the VLAN Tag on page 35. Benefit of VLAN Virtual local area networks (VLAN) lets you organize the Ethernet network by the field of application without changing the wiring or changing the IP network configuration. 34 Support of the DS6335-CS Ethernet Board January 2019

ECU 1 ECU 2 ECU 3 ECU 4 ECU 5 Ethernet switch Physical connection VLAN 1: Engine network VLAN 2: Exhaust network VLAN 3: Diagnostic network Using Ethernet switches that do not support VLAN Ethernet switches that do not support VLAN generally route Ethernet frames without considering the VLAN tag. As a consequence, multicast and broadcast messages are sent to all connected Ethernet devices.

37 Virtual Ethernet Setup Function Block Ports The Virtual Ethernet Setup function block does not provide signal ports or function ports. Tunable parameters The Virtual Ethernet Setup function block does not provide tunable parameters. Configuring the Basic Functionality (Virtual Ethernet Setup) Overview The function block type provides the following configuration features which influence the behavior of the basic functionality: Specifying the local IP address. Referencing the Ethernet network. Customizing the MAC address. Specifying the access to a VLAN. Specifying the local IP address With the local IP address, you specify two parts for IP networking: You specify a unique IP address for the virtual Ethernet adapter. You specify the subnetwork the virtual Ethernet adapter is connected to via the netmask (subnet mask/subnet prefix length). The netmask determines the most significant bits of the local IP address as the subnetwork address, the least significant bits determine the host address. The subnetwork address indicates the members of the same subnetwork. That means, the members of a subnetwork differ only in the host address. Tip If an external Ethernet devices is already configured, use the subnet mask/subnet prefix length of the configured device and the resulting subnetwork address. For example: An external Ethernet device uses the IP address and the subnet mask The resulting IP address range for the local IP address is with the subnet mask ( and are reserved IP addresses). Workflow to specify the local IP address you have to proceed in the following order: To specify the local IP address, 1. Select the IPv4 or IPv6 Internet protocol version for IP network communication. January 2019 Support of the DS6335-CS Ethernet Board 37

38 Using Ethernet Boards in ConfigurationDesk IPv4 addresses are 32 bit addresses that are commonly represented by four groups written in decimal numbers, such as IPv6 addresses are 128 bit addresses that are commonly represented by up to eight groups with hexadecimal numbers, such as 2001:db8:74b2:fa50:1:cb3e: 375: Specify how many most significant bits of the IP address are used to specify the subnetwork address. This is done via the subnet mask for IPv4 addresses or the subnet prefix length for IPv6 addresses. 3. Specify a unique IP address for the virtual Ethernet adapter. Remember that the IP address includes the subnetwork address. The subnetwork address must fit to the connected Ethernet network. For recommended IP addresses, refer to Recommended IP address ranges on page 38. Note Multicast IP addresses cannot be used to specify the local IP address and the use of reserved IP addresses is not recommended (refer to Unfavorable IP address ranges on page 38). Recommended IP address ranges The following table shows you the recommended IP address ranges for specifying the local IP address: IPv4 IPv fc00::1... fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff Unfavorable IP address ranges The following IP addresses are reserved IP addresses and not recommended to be used as the local IP address: The first IP address of the subnetwork if all bits of the host part are set to 0. For example: with the subnet mask IPv4 Broadcast addresses: The last IP address of the subnetwork if all bits of the host part are set to 1. For example: with the subnet mask Loopback addresses: (IPv4) and ::1 (IPv6) Referencing the Ethernet network You reference an Ethernet network by assigning an Ethernet Setup function block. The Ethernet Setup function block provides the access to a physical Ethernet adapter. Observe the following points: If several function blocks reference the same Ethernet Setup function block, you must ensure that all function blocks belong to only one application process. This means, the model port blocks of all function blocks that are assigned to the Virtual Ethernet Setup function block must be mapped to the same behavior model as the function blocks that are assigned to the Ethernet Setup function block. 38 Support of the DS6335-CS Ethernet Board January 2019

39 Virtual Ethernet Setup Function Block If two Ethernet setup function blocks (Virtual Ethernet Setup or Ethernet Setup function blocks) are members of the same IP subnetwork, it is recommended that the function blocks use different physical Ethernet adapter. The use of different Ethernet adapters prevents an unintended behavior. You specify the address of the IP subnetwork via the netmask and the local IP address. The netmask determines the most significant bits of the local IP address as subnetwork address. If a virtual Ethernet adapter references an IPv6 network via the Ethernet adapter of the DS6001 Processor Board, a task overrun can occur when you start the real-time application for the first time. However, you can restart the application without further restrictions. Using a default gateway A default gateway lets you send IP packets outside the local subnetwork that you specified via the subnet mask/subnet prefix length and the local IP address. The default gateway to other networks can be the router of your network. The virtual Ethernet adapter use the default gateway of the referenced physical Ethernet adapter. Note If a virtual Ethernet adapter uses the MAC address of the referenced physical Ethernet adapter (IP aliasing), the real-time application cannot send IPv6 packets outside the local subnetwork via the default gateway. To send IP packets outside the local subnetwork, use one of the following alternatives: Customize the MAC address of the virtual Ethernet adapter to send IPv6 packets. Use an IPv4 network. Customizing the MAC address If the custom MAC address feature is enabled, you can customize the MAC address of the virtual Ethernet adapter. When you customize the MAC address, observe the following points: Flags within the MAC address indicates the administration type and address type. The address type must be a unicast address. The following example of a MAC address shows you the position of the flags: MAC address 64:40:70:00:00: Flag Address type bit Administration bit Value Description Address type bit 0 The MAC address is a unicast address. 1 The MAC address is a multicast or broadcast address. January 2019 Support of the DS6335-CS Ethernet Board 39

40 Using Ethernet Boards in ConfigurationDesk Flag Administration bit 0 Value Description The MAC address is universally administrated by the manufacturer of the Ethernet device. 1 The MAC address is locally administrated. Ethernet devices of the data link layer, such as Ethernet switches, use the MAC address for routing. Ethernet switches cannot clearly route the Ethernet frames to a physical Ethernet adapter if the MAC address is not unique within the physical Ethernet network. Make sure that the custom MAC address of the virtual Ethernet adapters are unique within the physical Ethernet network, for example, by setting the administration bit. If you specify the same custom MAC address for several virtual Ethernet adapters (IP aliasing), reference the virtual Ethernet adapters to the same physical Ethernet adapter. 40 Support of the DS6335-CS Ethernet Board January 2019
