CAN interface series for Ethernet and Bluetooth

With CAN and CAN FD support.

CAN@net NT 200/420

Up to 4 x CAN (2 x CAN FD)
CAN-Ethernet gateway, bridge and PC interface

The CAN@net NT is offered in two variants, as CAN@net NT 200 with two classic CAN channels and as CAN@net NT 420 with four CAN channels, of which two channels can be switched between CAN and CAN FD. Both devices offer three operation modes and can be used as a PC interface as bridge and gateway.

How it works

Operation modes

CAN-Ethernet Gateway
In gateway mode the CAN@net NT can be directly accessed from e.g. Windows, Linux, VxWorks or QNX based systems as well as from embedded systems, by using a simple ASCII protocol over a standard TCP/IP socket. As CAN-Ethernet Gateway, the CAN@net NT offers easy, flexible access to four independent CAN systems (two CAN FD) via a LAN or via the Internet.

PC Interface
With the included VCI driver for Windows, the CAN@net NT can be operated like all IXXAT CAN PC interfaces. With the CAN@net NT, all VCI-based IXXAT tools, such as the canAnalyser, as well as customer-specific applications based on the VCI driver can be used. The VCI CAN driver offers the possibility to communicate with up to 128 CAN@net NT devices at the same time.

CAN-Ethernet-CAN Bridge
By using up to four CAN@net NT 420 (two CAN@net NT 200), a CAN-Ethernet-CAN bridge can be implemented, with each up to four independent CAN channels (2 for the CAN@net NT 200) per device. The bridge allows the exchange of CAN messages between CAN systems over long distances via TCP/IP, using existing Ethernet infrastructures. The segmentation of CAN systems also increases the reliability and failure safety of the entire system.

Functions

Filtering and multiplexing
With the help of mapping tables, the exchange of messages between all channels can be configured very flexibly. Filter and conversion rules can be applied to the CAN and CAN FD messages. As a result, the bus load in the individual networks can be reduced since only relevant messages are transmitted to the other network. For SAE J1939 applications a special mapping table is provided, adapted to the specific parameters. The data multiplexing/demultiplexing functionality enables the mapping of e.g. CAN-FD data to several standard CAN messages and vice versa.

Action Rules
In response to received messages, device or CAN bus status events, a variety of actions can be performed automatically, e.g. sending messages (CAN, CAN FD, MQTT), changing device settings or switching device LEDs. Action rules are created through intuitive drop-down menus for events and actions within the Windows-based device configuration tool.

MQTT for cloud connection
Whether device status or CAN/CAN FD data, the MQTT functionality of the CAN@net NT enables transmission of various information to the cloud – easily programmable using action rule lists. With free available broker services and APPs, e.g. status messages or system values can be easily transmitted to your smartphone or other devices.

Cyclic transmission
The cyclic transmission feature enables cyclic forwarding of messages. Both, messages and  cycle times are defined within a central cyclic transmission table.

Configuration

The configuration of the new CAN@net NT and the firmware upload is done with an intuitive to operate Windows configuration tool - via USB or Ethernet. With the tool, the configuration of filter, mapping, multiplexer or translation rules can be carried out very easily, without programming skills.
