“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 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.
APPLICATIONS:
● Control System
● Building Automation
● Factory Automation
● Distributed data acquisition
Data Interchange between Modbus TCP and DeviceNet
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.
UTILITY:
We provide GW-7434D Utility tools for Windows 98/SE/2K/XP, it includes:
● Online add/remove DeviceNet devices via Ethernet
● Online monitor and configure devices status via Ethernet
● Get/Set Modbus/TCP input/output memory address
● Support DeviceNet I/O mapping table
● Show DeviceNet devices connection status
● Support communication mode setting
TYPICAL APPLICATIONS:
● Modbus TCP/RTU slave to DeviceNet master gateway
● A single Modbus/TCP to Multi-Modbus/RTU converter
● Protocol converter with VxComm technique
