Introduction

The GW-7434D is an economic solution that provides a communication protocol transformation between the DeviceNet protocol and the Modbus TCP protocol. This module solves the problem to connect an existing DeviceNet network to the Ethernet-based PLC, HMI or SCADA for setting up a control or monitoring system. Different to the GW-7243D, the GW-7434D offers the Predefined Master connection Set function and Group 2 only Server function as a DeviceNet master, and enables accessing the DeviceNet slaves automatically and cyclically. If the PLC, HMI or SCADA would like to access the DeviceNet slaves and simultaneously communicate with the Modbus slaves or COM-based devices connected with the RS-232 or RS-485 port of the GW-7434D, the GW-7434D can be the Modbus TCP server or VxComm server to exchange the data with those devices.

  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.
