I-7540D
CAN to Ethernet Gateway

 
 
     
 

Internet communications using TCP/IP is increasing in the industrial sector. Using Ethernet for network in industrial area is appealing because the required cabling is already installed. The CAN-Ethernet Gateway from ICP DAS is a solution that enables CAN networks to be coupled together over the Internet/Ethernet, whereby remote monitoring and control is possible. The CAN-Ethernet Gateway controls networked communication and makes a transparent CAN-based application interface available to the user.

The device supports a transparent, protocol-independent transfer of the CAN messages, thus allowing its implementation into a wide range of possible applications. Furthermore, the CAN-Ethernet Gateway can be used with various higher layer CAN protocols (e.g. CANopen, DeviceNet or other proprietary protocols). The following figure shows the application architecture for CAN-Ethernet Gateway .

Furthermore, I-7540D also can be used as Ethernet to CAN/RS-232/485 Device Server. The Device Server is an appliance that network enables any device with a serial communication port. By virtue of its independent operating system, protocol independence, small size and flexibility, Device servers are able to meet the demand of virtually any network-enable application. Most devices don't have network ports. I-7540D allows those devices to become connected to the network.

The VxComm technology can be used to simulate COM/CAN ports of the I-7540D to become a COM port of PC . With the help of VxComm driver, users can access the remote COM/CAN ports of the I-7540 just as them would access the PC's COM port. The block diagram of data processes in I-7540D is given as follows:
