Description
Internet communications using TCP/IP is increasing in the industrial sector. Using Ethernet for networking in industrial areas is appealing because the required cabling is already installed. The CAN-Ethernet Gateway 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 I-7540D 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).
Furthermore, the I-7540D can also be used as an 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, the Device server is able to meet the demand of virtually any network-enabled application. Many devices don't have network ports. The I-7540D allows those devices to become connected to the network.
