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-MTCP 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-MTCP controls networked communication and makes a
transparent CAN-based application interface available to the user.
The I-7540D-MTCP has supported a major function, convert Modbus
TCP and Modbus RTU to CAN. It allows a Modbus TCP/RTU master to
communicate with CAN devices on a CAN network. Furthermore, the I-
7540D-MTCP also supports a transparent, protocol-independent transfer
of the CAN messages (pair-connection), thus allowing its implementation
into a wide range of possible applications.
