ICP DAS USA I-7540D - Manual (Page 4)

1. Introduction
“Embedded Internet” and “Embedded Ethernet” are hot topics today.
Nowadays the Ethernet protocol becomes the de-facto standard for local area
network. Via Internet, connectivity is occurring everywhere, from home appliances
to vending machines to testing equipment to UPS…etc. Using Ethernet for
network in industrial area is appealing because the required cabling is already
installed. The i-7540D 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 i-7540D 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 i-7540D 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 the i-7540D.
