Note To connect the CAN-ETH to a PC (Personal Computer) or any other device with data terminal equipment (DTE) pinout you need a null-modem or cross-over cable.

Ethernet & IP configuration

Before configuring the CAN-ETH, obtain a unique static IP address, subnet mask, and default gateway address from your network administrator.

The factory default IP address of the CAN-ETH is 169.254.0.10 which is in the Automatic Private IP Addressing (APIPA) address range.

There are several methods of configuring the unit’s IP address:

  1. Removing your PC from your corporate network and using a cross-over network cable (see [ConfigCrossOver]).

  2. Via the diagnostic port and a terminal program like HyperTerminal (see [ConfigTerminal]).

  3. Leaving your PC connected to your corporate network and temporarily changing the IP settings on your PC to match the subnet of the CAN-ETH (see [ConfigChangeIP]).

Note In order to connect to the CAN-ETH via TCP/IP, your PC must be on same IP subnet as the gateway. In most situations this means that the first three numbers of the IP address have to be identical.

IP setup using a web browser and a cross-over network cable

This method applies only to operating systems like Windows, which support APIPA (Automatic Private IP Addressing). It also requires your PC to be configured for DHCP. If your computer is configured with a static IP address, follow the procedure in [ConfigChangeIP].

  1. Disconnect your PC from your corporate network. If your computer is configured for DHCP it should now automatically fall back to use a default IP address from the APIPA range 169.254.x.x (Windows PCs only).

  2. Connect an Ethernet crossover cable from the CAN-ETH to the computer.

  3. Start Internet Explorer.

  4. In the address box, type 169.254.0.10 and then press Enter.

  5. Click Configuration… and then Ethernet & IP in the menu on the left side of the page.

  6. Enter the IP address, subnet mask, and gateway address assigned to your CAN-ETH, then click Save.

  7. Reconnect your computer to your corporate network.

IP setup using a terminal program like HyperTerminal

  1. Connect a null modem RS-232 cable between your PC and the CAN-ETH's diagnostic port.

  2. In Windows XP, click Start, point to All Programs, point to Accessories, point to Communications, and then click HyperTerminal.

  3. When HyperTerminal starts, it opens a dialog box and asks for a name for the new connection. Enter a name (for example, deviceconfig) then click OK.

  4. The Connect to dialog opens. Select the COM port you will be using in the Connect using drop-down list box, then click OK.

  5. Select 9600, 8, None, 1, None in the COM Properties dialog, then click OK.

  6. HyperTerminal is now connected to the serial line.

  7. Keep the space bar pressed in HyperTerminal and power-cycle your device at the same time.

  8. A menu should appear after one or two seconds showing device information, the current IP configuration and a > prompt.

  9. Type SETIP, then press Enter within 10 seconds after the prompt is shown:

    Diagnostic mode
  10. The device will show current values and prompt for new values for IP address, net mask and gateway address. Enter the new values and press Enter. A key press must be received at least every 10 seconds otherwise the device will go back to RUN MODE and resume normal operation.

  11. The gateway will return to the main prompt. Type X and press Enter to leave DIAG MODE and resume normal operation indicated with RUN MODE.

Temporarily changing the IP settings on your PC

This method involves manually assigning an IP address to your PC in the same subnet as the gateway. The default subnet of the gateway is 169.254.0.0/16.

  1. Connect the CAN-ETH to your Ethernet network.

  2. On a Windows PC, open the Control Panel and double-click on Network Connections. Right-click on the Network Connection associated with your network adapter and select Properties:

Note In order to connect to the CAN-ETH via TCP/IP, your PC must be on same IP subnet as the gateway. In most situations this means that the first three numbers of the IP address have to be identical.

Monitoring and diagnostic

The CAN-ETH offers several web pages which allow monitoring of the status of the different communication networks and the device performance.

Device status

The Overview page shows the principal device status as shown in the following picture:

Overview screen
Figure 3. Overview page

The value shown in the Device row represents the device status register which keeps track of run-time faults. All run-time faults are latched and must be reset by the user. The following faults can be listed here:

OK

The device is fault free.

Watchdog reset

This warning indicates that the device was reset by it’s internal watchdog supervision circuit.

Brown out reset

This warning indicates that the device was reset by it’s internal supply voltage monitoring circuit. This fault occurs when the supply voltage drops below the lower limit.

Device out of memory

This warning indicates that the internal dynamic memory has been exhausted and due to this a certain function could not be completed.

Device configuration data write failure

This alarm indicates that the configuration data could not be written to the non-volatile memory. Configuration data changes will be lost once the device is power-cycled or reset.

Reset to factory defaults

This alarm indicates that the device' configuration data was reset to factory defaults. The device requires re-commissioning.

The CAN controller status indicates the status of the CAN interface and can be in one of the following states:

ACTIVE

The CAN bus is fault free.

PASSIVE

CAN’s built in fault confinement mechanism has set the node to error passive state due to a large number of errors on the CAN bus. This warning indicates a wiring error.

BUS-OFF

CAN’s built in fault confinement mechanism has set the node to bus-off state due to excessive errors on the CAN bus. This alarm indicates a wiring error. The CAN-ETH will not transmit or receive any message on the CAN bus once entered this state. The device needs to be manually restarted on order to recover from this fault.

CAN communication status

The CAN Status page shows status and statistics about the CAN bus traffic. These values provide valuable information used to troubleshoot CAN problems. This page is automatically updated every 5 seconds.

CAN communication status screen
Figure 4. CAN communication status page
Note This page shows accumulated readings since the CAN-ETH was last activated or reset. If power to the CAN-ETH is lost, all cumulative values are reset to zero.

The CAN communication channel between a Woodward CANopen based control and the CAN-ETH can be in one of the following states:

OK

The CAN communication channel with the Woodward CANopen based control has been established. The Woodward device is cyclically sending visualisation data via its TXPDO.

WAIT

The presence of a supported Woodward CANopen based control has been detected however the CAN-ETH is currently waiting to receive a complete visualisation data set.

TIME-OUT

No CANopen PDO was received for a period of 1 second. A Woodward control must be configured to transmit cyclically visualisation data using a TXPDO with a specific COB-ID number and the correct Data Protocol.

The following statistics are maintained:

Messages received

A counter that increments each time an inbound CANopen PDO matching the shown COB-ID is successfully received.

Messages sent

Note After a remote restart a Watchdog reset alarm is shown on the device' home page. This is a side-effect of the remote restart procedure and the alarm shall be ignored and cleared.

Protocol Description

The CAN-ETH gateway sends and receives CAN frames via TCP/IP using UDP datagrams. UDP was chosen over TCP as UDP is similar to CAN, a connectionless protocol.

The implemented protocol is conceptually easy to understand, easy to implement, efficient and gives high performance.

UDP Datagram

The default UDP port is 11898.

One UDP datagram can contain up to 16 CAN frames. How CAN messages are embedded in a UDP datagram is shown in the following drawing:
