Modbus TCP server/RTU slave to CANopen master gateway -- GW-7433D

Supplier: ICP DAS Co., Ltd

The GW-7433D is a solution that provides a communication transformation between CANopen protocol and Modbus/TCP & RTU protocol.

Price Guide: POA

It solves a mission-critical problem, and 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 network, the GW-7433D is a CANopen master device. It supports PDO and SDO functions to communicate with slave devices. From the view of Modbus TCP & RTU network, GW-7433D plays a Modbus TCP server or Modbus RTU slave role to receive the commands from Modbus TCP client or Modbus RTU master, and to reply the information to Modbus TCP client or Modbus RTU slave. 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.
