Features

gw-7434d Diagram“Embedded Internet” and “Embedded Ethernet” are hot topics today. Nowadays the Ethernet protocol becomes the de-facto standard for local area network. Via Internet, connectivity is occurring everywhere, from home appliances to vending machines to testing equipment to UPS…etc. Using Ethernet for network in industrial area is appealing because the required cabling is already installed. The GW-7434D DeviceNet Master to Modbus TCP Gateway from ICP DAS is a solution that provides a communication protocol transfer the DeviceNet and Modbus/TCP protocol and solves a mission-critical problem: connecting an existing DeviceNet network to Ethernet-base PLCs and PC-based configuration and monitor system. it enables DeviceNet networks to be coupled together over the Internet/Ethernet, whereby remote monitoring and control is possible.

The GW-7434D can be a DeviceNet master device in the CAN bus on the DeviceNet network. It is a “Predefined Master connection Set”, and supports Group 2 only Server functions to communication with slave devices. In addition, we also provide utility software for users to configure their device parameters for the GW-7434D. The following figure shows the application architecture for the GW-7434D.

  • Programmable DeviceNet Master MAC ID
  • Programmable DeviceNet transfer-rate 125K, 250K, 500K
  • Supports maximum DeviceNet devices up to 63
  • Predefined Master/Slave Connection Set
  • The maximum Fragment number is (Input/Output) up to 64
  • Supports I/O Operation Mode: Poll, Bit-Strobe and Change Of State/Cyclic
  • Supports one Poll, one Bit-Strobe, one COS, one Cyclic IO connection for each DeviceNet device when connected with this module
  • Supports on-line adding device into and removing device from network
  • Supports boot-up auto communicate with slave devices
  • Converter single Mobbus/TCP to multi Modbus/RTU, setting by Utility
  • Supports VxComm technique for every COM port of controller, set by Utility
  • Allowed multi-client (or master) access simultaneously
Modbus RTU, DeviceNet, VxComm Technique
  • Applications:

    • Control Systems
    • Building Automation
    • Factory Automation
    • Districuted Data Acquisition
  • Data Interchange between Modbus TCP and DeviceNet
    • 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 "nternal Memory” by one network interface
    • Allowing the data to be read/wrote through the other network interface
Internal Memory Table
  • GW-7434D Utility
    • Add/Remove online DeviceNet devices via Ethernet
    • Monitor and configure devices online via Ethernet
    • Get/Set Modbus/TCP input/output memory address
    • Supports DeviceNet I/O mapping table
    • Shows DeviceNet devices connection statuses
    • Supports communication mode setting

    I-7243D Utility

    • Typical Applications
      • Modbus/TCP server to DeviceNet master gateway
        • The GW-7434D can act as a Modbus/TCP server 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 commands.


      • A single Modbus/TCP to multi-Modbus/RTU Converter
        • GW-7434D can be a single Modbus/TCP to multi-Modbus/RTU converter. You can simply use the Utility software to configure the device and then set connections between SCADA HMI software and the GW-7434D.

      • Protocol Converter with VxComm Technique
        • GW-7434D can also be able to link to serial devices that do not 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
