Manual
 
 
 
DeviceNet is one kind of the network protocols based on the CAN bus and mainly used for embedded network for machine control, such as textile machinery, printing machines, injection molding machinery, or packaging machines, etc. DeviceNet is a low level network that provides connections between simple industrial devices (sensors, actuators) and higher level devices (controllers). It allows direct peer to peer data exchange between nodes in an organized and, if necessary, deterministic manner. DeviceNet defines a connection-based scheme to facilitate all application communications. A DeviceNet connection provides a communication path between multiple endpoints. The endpoints of a connection are applications that need to share data.

The I-8420 main unit based on the modular design offers many good features to the users and provides more flexibility in data acquisition and control system. In addition, ICP DAS also presents a 8420 Utility tool to allow users to configure and create the EDS file for the specific IO modules plugged in. Therefore, users can easily apply the I-8420 embedded controller in DeviceNet network. The application architecture is demonstrated as follows:

  I-8420 Utility
 
     
 
I-8420 main unit can be plugged in the DCON(/I-8K/I-87K) IO modules to create a customized DeviceNet slave device and application. Before applying the I-8420 in DeviceNet applications, users must understand the relationship between these DeviceNet applications and assembly objects within I-8420 DeviceNet slave. In order to allow user to easy apply the device on the network, ICP DAS also provides the 8420 Utility tool to configure the IO connection path, assembly and application objects information and create the EDS file of the device.
