Product Upgrade Notice: GW-7433D, CANopen/Modbus TCP Gateway, the firmware v2.0 with new functions is released
The GW-7433D acts as a CANopen master to Modbus slave gateway which can allow the Modbus master, such as PLC, PAC or HMI, to access the CANopen slaves. It allows the multiple Modbus TCP clients, one RS-232 Modbus RTU master, and one RS-485 Modbus RTU master to communicate with itself at the same time. In order to close and satisfy the users requirements, ICP DAS announces the new firmware and utility to the GW-7433D. The new firmware provides the disconnection detection of the CANopen/Modbus communication interfaces, the RTR Mode and Un-RTR Mode, and more data types for data exchange. The disconnection detection is helpful when the Modbus TCP client is lost or the CANopen slave malfunctions. The RTR and Un-RTR mode offer the flexibility for observing the data from the TxPDOs. The new utility gives the friendlier user interface and diagnostic tool which is useful to check the communication status between the GW-7433D and the CANopen slave devices while applying the GW-7433D in the CANopen network. By means of the diagnostic tool, users can easily set up their CANopen networks and quickly solve the CANopen communication problems between the GW-7433D and CANopen slaves. These upgrades let users use the GW-7433D more flexible and simple.
