Introduction This document describes the features and objectives of the CAN-Ethernet gateway AnaGate CAN duo. This device is part of a product line, whose single devices only differ in the number of CAN interfaces and/or the device case. In this manual the term AnaGate CAN Gateway is uniformly used, if no specific model is addressed or it is not necessary to differentiate.
Chapter 1. Description The AnaGate CAN Gateway connects a PC, an embedded PC or an other general device to one or more CAN busses via the TCP/IP network protocol. It basically works as a CAN master with no own CAN identifier on the bus. For this reason the AnaGate CAN duo provides an ethernet interface and two independent electrically isolated CAN interface. Controlling and configuration of an AnaGate CAN Gateway is made through TCP/IP.
Description • Coupling of two independent CAN networks via the internal CAN/CAN bridge (not possible for AnaGate CAN uno and AnaGate CAN USB). 1.2. Specification Technical aspect Measurements CAN bus Digital IO LAN interface Voltage supply Ambient temperature Specfication Desktop casing 155mm x 105mm x 40mm , fixable on DIN rail with optional adapter kit Weight approx. 295g Baud rate 10, 20, 50, 62.
Description • 1 x plug-in power supply unit, compatible with country of delivery: EU, US or UK. 1.4. Interfaces and plugs 1.4.1. AnaGate CAN duo - front view Figure 1.1.

Description 1.4.2. AnaGate CAN duo - rear view Figure 1.2. AnaGate CAN duo, back panel The rear panel of the AnaGate CAN Gateway features the following connectors and LEDs (from left to right): Power LED This green LED lights up when voltage is being supplied. Power supply The AnaGate CAN Gateway can be power supplied in two different ways.
Chapter 2. Configuration 2.1. Initial installation First the AnaGate CAN Gateway must be supplied via the power plug with a tension from 9 to 24 V. Insert the included LAN cable into the plug labelled LAN and connect it either to a hub or switch. If connecting directly to a PC use a crossover LAN cable (not in scope of delivery) instead of the included LAN cable. 2.1.1.
Configuration can be e.g. used. If neccessary the settings of the network interface on the configuration pc has to be changed temporarily. 2.2. Network settings On the page IP Settings the following settings can be changed. DHCP Here you can switch between static IP and dynamic (via DHCP) addresses. If DHCP is being used, the remaining fields are ignored, because this information is retrieved from the DHCP server. In this case, a DHCP server must be available and accessible in the network.
Configuration The inputs will be taken over immediately after clicking the button Save settings and saved permanently on the AnaGate CAN Gateway . A restart of the device is not necessary for activation of the settings. Note Maybe the ARP cache of the PC has to be deleted to find the device with the changed IP address. 2.3. CAN settings On the page CAN Settings the global settings for all existing CAN interfaces are displayed and can be changed individually. Figure 2.3.
Configuration Boot with operational mode Initial operating mode of the CAN controller. Default value is offline. offline The CAN controller is not active on the CAN bus (offline). normal Normal operating mode. The default setting of CAN baud rate is used. listen In listen mode the CAN passive. CAN messages are no messages can be sent error). The default setting rate is used. loopback In loopback mode every sent CAN message is mirrowed back by the CAN controller (no ACK, no errors).
Configuration Figure 2.4. HTTP interface, CAN settings Reception timer interval This value specifies the frequency which is used to examine if new CAN telegrams are available in the internal driver buffer. The more frequently this examination is done, the shorter is the latency of the re-transmission of the CAN data via ethernet. On the other hand, its maximum message throughput is decreased. The interval is defined in micro seconds, default value is 3000.
Configuration Figure 2.5. HTTP interface, Status TCP Receive Number of via TCP/UDP received CAN messages (CAN firmware) TCP Transmit Number of via TCP/UDP transmitted CAN messages (CAN firmware) CAN Receive Number of received CAN messages (CAN bus, CAN driver) CAN Transmit Number of transmitted CAN messages (CAN bus, CAN driver) CAN Discard • Timeout sending CAN telegram (1s) This indicates that no active partner is connected to the CAN bus (no ACK received).
Configuration • The firmware discards outgoing CAN telegrams because the send buffer is running full (1000 entries) This happens when CAN telegrams are not sent fast enough successfully to CAN bus. This may be a resultant problem of timeouts during transmission or of overloading the CAN bus concerning the current used baud rate.
Configuration Figure 2.6. HTTP interface, Lua settings Browse... Opens a file upload dialog to select a Lua script file. Upload Uploads the selected script file to the device. Clear Clears the current script file selection. Boot script Script file executed on system startup. Via the button Delete the boot script can be deactivated. Only one boot script is allowed. Running script Displays the currently executing script file. Via the button Stop the execution can be cancelled.
Configuration To start the execution of a script click on the button Start. Via button Delete a script can be deleted on the device and via Boot a script can be defined as boot script. script output area In this text area the standard output (stdout) of the currently executing script is displayed. Via the button Clear this text area can be cleared. error output area In this text area the standard error output (stderr) of the currently executing script is displayed.
Configuration Warning The outputs are not short-circuit-safe! 2.8. Factory reset In order to restore the default factory settings, hold the RESET for approx. 10 seconds. If the device is reset successfully, the yellow LED blinks until the RESET is released. The default factory settings are activated immediately without a restart of the device: IP address Address type Network mask Gateway 192.168.1.254 static 255.255.255.0 192.168.1.
Configuration Between two single digits a delay of 1 seconds is made, and between the IP address and subnet mask two fast flashes are pulsed out. Figure 2.8. AnaGate CAN Gateway, Example blinking output 2.9. Firmware update The device firmware of the AnaGate CAN Gateway is updated via the integrated web server of the device. On the home page of the web server the current firmware information is displayed. Figure 2.9.
Configuration Figure 2.10. HTTP interface, firmware update • Select the update package (file extension *.upd) via the Browse button. • Clicking on the button Upload loads the update file to the device and starts the update process. • During the update process several installation messaged are displayed on the website. If the update is successfully finished, Update done! is displayed. When the update is finished the browser navigates back to the home page. Check, if the new firmware version is display here.
Chapter 3. Fields of application If the AnaGate CAN Gateway is connected to the CAN bus, mind the following facts: • CAN_L: This line has to be connected to the CAN_Low line of the CAN bus. • CAN_H: This line has to be connected to the CAN_High line of the CAN bus. • GND: This line can be connected optionally to GND of the other bus devices. 3.1. Gateway mode In gateway mode the CAN messages are transferred transparently over TCP/IP between the CAN network and the host platform (e.g.
Fields of application • Self-created batch files which are executed via the included Lua interpreter with integrated AnaGate software API. 3.2. Bridge mode In the bridge mode two arbitrary CAN networks can be interconnected by two AnaGate CAN Gateways. The CAN messages are exchanged transparently over TCP/ IP between the two devices in both directions. It is possible to mix different AnaGate CAN Gateway models in bridge mode.
Fields of application • The baudrate of the partner device. The baudrate of the parter device is independant of the own baudrate and has to be configured separatly. So, it is possible to interconnect networks with different baudrates. • The internal termination resistor is to be set on/off for the CAN port of the parter device. On destination devices, which can not software-configure the CAN bus termination (like the AnaGste CAN X2/X4/X8), this setting is ignored.
Fields of application To interconnect the two CAN interface on a single device, the own IP address or 127.0.0.1 has to be used. In this case the specified remote baud rate and termination is used on the interconnected interface. 3.3. CANopen Conformance Test Tool The CANopen Conformance Test Tool (CCT) is a software tool, which is created and supported by the CAN in Automation (CiA). It is used by the CiA to certificate CANopen devices.
Appendix A. FAQ - Frequently asked questions Here is a list of frequently asked questions. A.1. Common questions Q: No network connection (1) A: Please check the physical connection to the device first. In general the AnaGate has to be connected directly to a personal computer or to an active network component (hub, switch). If the AnaGate device is connected to a personal computer a cross-wired network cable must be used to connect the device, otherwise the included network cable is to be used.
FAQ - Frequently asked questions Q: No network connection after changing the network address A: After changing the network address of the AnaGate device via web interface the device is not longer reachable. The used internet browser displays only an empty web page, additional error messages are not available. Please check if your anti-virus software has blocked the new network address. After changing the network address you are redirected to the new network address in the browser.

FAQ - Frequently asked questions Note it may work with lower baud rates without termination, but it is recommended to use a termination. Q: Receiving a NAK when sending a CAN telegram. A: If no CAN partner is connected to the AnaGate CAN (aka the CAN network), it is not possible to send CAN telegrams. The AnaGate CAN gets a NAK from the CAN controller. These NAK errors are sent to the AnaGate client via a data confirmation telegram.
