CAN Bridges and Gateways - CAN-Interfaces and gateways

CAN Bridges and Gateways

The use of bridges and gateways opens up a large number

of conguraon possibilies. For example, CAN and DeviceNet

systems can be implemented over a larger area, devices

without CAN interfaces can be connected to CAN systems

or CAN and DeviceNet systems can be coupled using dierent

technologies, such as Bluetooth or Ethernet.

CAN INTERFACES AND GATEWAYS

CAN Bridges

CAN bridges can link networks of dierent bit rates or protocols with

each other. They are based on the store-(modify)-forward principle

where CAN or DeviceNet messages are received by a sub-network and

then transmied to the other sub-network. Translaon and lter rules

can also be used, allowing a protocol adaptaon to be carried out. A

bridge can, therefore, provide simple gateway funcons. CAN bridges

are appropriate for creang hierarchical networks by transferring only

the

informaon to the connected sub-networks via bridges which are

relevant to the sub-network.

The bridge funcon can also be executed with the aid of other

transmission systems. For example, the CAN-Ethernet-CAN bridge is

set-up by two CAN@net II gateways which enable connecon to

remote CAN networks.

Gateways

As an extension to the CAN bridges, CAN gateways allow access to

CAN networks via other communicaon systems. In each case, the

protocols of the connected bus systems are mapped to the other com-

municaon model.

Besides a PC interface and bridge mode, the CAN@net II and CANblue

II provide a gateway mode enabling easy remote access to CAN

and DeviceNet networks for e.g. mobile devices by using

a standard ASCII protocol.

Application scenario in wind turbine

Three pitch control-drives shall communicate with

the master controller via CAN. IXXAT CAN

Repeaters enable star connecon of the

individual blades and enable stable

communicaon by eliminang EMI

eects and rebuild signals for

transmission via sliprings.
