GW-7433D

“Embedded Internet” and “Embedded Ethernet” are hot topics today. Ethernet protocol is standard for local area networks. Via Internet, connectivity is occurring everywhere, from home appliances to vending machines, to testing equipment, to UPS. Ethernet for networks in industrial area is appealing because the required cabling is already installed. The GW-7433D is a solution that provides a communication transformation between CANopen protocol and Modbus/TCP protocol. It solves a mission-critical problem: connecting an existed CANopen network with Ethernet-base master device as long as this master device supports Modbus/TCP protocol. It enables CANopen networks to be coupled together with the Internet/Ethernet, whereby remote monitoring and controlling is achieved.

For CANopen networks, the GW-7433D Modbus TCP Server / RTU Slave to CANopen Master is a CANopen master device. It supports PDO and SDO functions to communicate with slave devices. From the view of Modbus/TCP networks, GW-7433D plays a Modbus/TCP server role to receive the commands from Modbus/TCP client or to reply the information to Modbus/TCP client. We provide Utility software for users to configure the parameters of CANopen salves or GW-7433D. When GW-7433D boots up, it will collect the necessary information from all slaves which are predefined in the GW-7433D by using Utility. The following figure shows the application architecture for the GW-7433D.
