Typical Applications
Application 1: Modbus TCP/RTU slave to DeviceNet master gateway
The GW-7434D can act as a Modbus TCP/RTU slave to DeviceNet master gateway. Using the module, users don’t need to take care of the detail of the DeviceNet protocol. The module will implement the DeviceNet protocol automatically. It mainly supports the Predefined Master/Slave Connection Set functions to allow users to merge I/O data into DeviceNet network by using Modbus TCP/RTU commands.
Application 2: a single Modbus/TCP to multi-Mosbus/RTU converter
GW-7434D can be a single Modbus/TCP to multi-Modbus/RTU converter. You can simple use the Utility software to configure the device and then set connection between SCADA, HMI software and the GW-7434D.
Application 3: protocol converter with VxComm technique
GW-7434D can also be able to link to serial devices that don’t support Modbus/RTU. To use this function, you will need to install VxComm driver on host PCs. After installation, you will be able to access the remote COM ports via the standard serial driver.

Data Interchange
The GW-7434D provides centralized data storage, “Internal Memory”, for data that is shared between the DeviceNet and Modbus/TCP network. Data is placed into the “Internal Memory” by one network interface, allowing the data to be read/wrote through the other network interface.
