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.
Features
- Programmable standard CANopen baud, such as 10Kbps, 20Kbps, 50Kbps, 125Kbps, 250Kbps, 500Kbps, 800Kbps and 1Mbps.
- Support maximum 50 TxPDO, 50 RxPDO, 15 SDO to SDO server.
- Support communication object: TxPDO, RxPDO, and server SDO.
- Support on-line configure CANopen slaves.
- Communicate with CANopen slaves automatically when GW-7433D boots up.
- Allow 5 Modbus/TCP masters to access GW-7433D simultaneously.
- CANopen Version: DS301 V4,01 .
- Device Profile: DSP-401 v2.0 .
Applications
- Control Systems
- Building Automation
- Factory Automation
- Distributed data acquisition
Utility
- Add/remove CANopen slaves via Ethernet
- Online getting and setting the CANopen slaves configurations via Ethernet
- Get/Set Modbus/TCP input/output memory address
- Display CANopen I/O mapping table
- Configure the parameters of Ethernet and CAN bus
How Do I Use the Gateway?
- Select proper CANopen slaves for users’ application.
- Use the GW-7433D Utility to link the GW-7433D Module via Ethernet.
- Set the IO parameters of CANopen slave devices into GW-7433D by GW-7433D Utility.
- The GW-7433D module will initialize automatically and implement the GW-7433D in your Modbus/TCP network.
