Gateways and Bridges/Router

open up a variety of connection possibilities

 

With bridges and gateways CAN or CAN FD systems can be coupled or implemented over a larger area, devices without CAN can be connected to CAN systems or CAN systems can be coupled using different technologies, e.g. Bluetooth, Ethernet or PROFINET.

IXXAT CME/PN

PROFINET CANopen Gateway

The IXXAT CME/PN is a powerful and easily configurable gateway for connecting CANopen devices and networks to PROFINET systems. The gateway enables bi-directional data exchange allowing for both the integration of existing, low-cost CANopen devices into PROFINET systems as well as the provision of data from PROFINET for use in CANopen.

How it works

The gateway operates as a PROFINET I/O device and uses slots and sub-slots for data exchange. On the CANopen side, the device acts as a CANopen NMT master with PDO and SDO support. 

The gateway configuration is accomplished easily by using the IXXAT configuration tool which is included free of charge. The configuration tool automatically generates a CDC configuration file for the CANopen network as well as a GSDML file for Profinet.
The CANopen configuration is based on EDS files. The GSDML file allows for simple gateway integration into PROFINET networks and the access of PLC applications to the gateway. At this, the gateway is represented as a single I/O device. All data on the CANopen side which is exchanged through the gateway with the PROFINET network are defined in the GSDML file as variables with variable name, data size and data direction. This unprecedented dual side approach simplifies the configuration significantly. 

The gateway has an integrated 2-port switch, thus allowing easy integration into line topologies. The connection to the CANopen bus and the power supply is made using screw terminals. Device configuration and firmware upgrades can be made via a USB 2.0 port or remote via the Ethernet port.

CAN bridges and CAN gateways are infrastructure components with which complex network structures can be implemented.

A CAN bridge can connect CAN or CAN FD networks of different bit rates or protocols with each other. It is based on the store-(modify)-forward principle where CAN / CAN FD messages are received by a sub-network and then transmitted to the other sub-network. Translation and filter rules can also be used, allowing a protocol adaptation to be carried out between the sub-networks. Unlike the CAN / CAN FD repeater, the CANbridge enables the enlargement of the maximum network size so that the sub-systems are fully self-sufficient with regard to bus arbitration. Independent of each other in terms of their real-time behavior, CAN sub-networks connected by bridges are to be regarded as independent networks.

The bridge function can also be executed with the aid of other transmission systems. For example, the CAN-Ethernet-CAN bridge is connected via two Ethernet-TCP/IP gateways which enable connection to remote CAN / CAN FD networks.

As an extension to the CAN bridges, CAN gateways allow for access to CAN networks via other communication systems. In each case, the protocols of the connected bus systems are mapped to the other communication model.

Application samples:

CAN bridge
Using the CANbridge NT, CAN or CAN FD systems within a building can be separated for every flor, due to this the maximum system expansion can be easily extended.


CAN Bridge Application Sample

CAN gateway
CAN@net NT allows large distance coupling of CAN or CAN FD systems via Ethernet, e.g. for connecting the engine room with the control room on a ship.
