1.3 Module Characteristics
"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 GW-7433D from ICP DAS is a solution that provides a
communication protocol to transfer the Modbus TCP/RTU to CANopen
protocol and solves a mission-critical problem, connecting an existing
CANopen network to Ethernet-base PLCs and PC-based configuration and
monitor system. It enables CANopen networks to be coupled together over the
Internet/Ethernet, whereby remote monitoring and control is possible.
The GW-7433D can be a CANopen master device in the CAN bus on
the CANopen network. On the Ethernet network, it acts as a Modbus TCP
server of Modbus RTU slave. Users can use Modbus TCP/RTU class 0, class
1 and partial class 2 functions to communicate with it. In addition, we also
provide Utility software for users to configure their device parameters for the
GW-7433D. The following figure shows the application architecture for the
GW-7433D.
