DeviceNet based on the CAN bus is one of the world's leading device-level networks for industrial automation. In fact, more than 40% of end users surveyed by independent industry analysis report choose DeviceNet over other networks.
ICP DAS has been developing CAN based DeviceNet protocol products for several years, include PCI interface card, gateway, DeviceNet IO and DeviceNet module for ICP DAS’s PACs — WinPAC/WinCon/ LinCon/I-8000 s eries main contol unit. We also help customers to resolve various DeviceNet network technology problems. In addition, we can provide DeviceNet solution for users. ICP DAS also holds DeviceNet conference, exhibition and training course all over the world.

DeviceNet Introduction    DeviceNet Solutions

 
   
 
 
     
 

The DeviceNet network is a flexible open and low-cost option which you can use to connect industrial devices to a network and to eliminate costly and time-consuming hardwiring. Direct connectivity improves communication and provides device-level diagnostics or easily accessible through hardwired I/O interfaces.

DeviceNet is an open standard, it saves time and money at start-up—a key advantage for OEMs. Because it uses a trunk line/drop line topology, a single DeviceNet cable provides power and communication signal to all devices on the network. This significantly reduces the amount of wiring required and greatly simplifies installation. Adding and removing devices from the network is a simple process—a key advantage for end-users. You do not need to add or remove any wires. Simply connect or disconnect the device to or from the trunk line and configure the scan list. It really is that easy.

DeviceNet features

  • Trunk line, drop line configuration
  • Node removal without breaking trunk line
  • Up to 64 addressable nodes
  • Signal and 24Vdc Power in same cable
  • Selectable Data Rates (125k, 250k, 500k)
  • Both Sealed and Open-Style connections
  • 120 ohm terminator at each trunk line end

There exist two memory areas, “Input Area” and “Output Area”. The input data of all DeviceNet slaves would be stored in the “Input Area” by DeviceNet master scan engine. Oppositely, the output data of those DeviceNet slaves would be in the “Output Area”. Please refer to the following figure.

Users can read a bulk data from “Input Area” in the DeviceNet Master module, like PISO-DNM100U or I-8124W. This bulk data contains multiple devices’ input statuses. If one of the input status of the remote DeviceNet slave changes, the corresponding data located in the “Input Area” would change immediately. Oppositely, the “Output Area” contains multiple devices’ output data. Users may change the output value of a certain device by changing the corresponding data located in the “Output Area”.

DeviceNet slave series
CAN-8x24 series and CAN-2000D series are especially designed for combining sensors and actuators into DeviceNet network. All of them provide corresponding EDS file for standard DeviceNet master interface. The mainly differences between CAN-8x24 series and CAN-2000D series are the product size and the capabilities of expansion. CAN-8x24 series is useful for centralizing control system. It provides flexible I/O selections to match various applications. The character ‘x’ indicates how many expansion slots it has. Therefore, we provide CAN-8124/CAN-8224/CAN-8424 for 1/2/4 expansion slots. Each slot allows you plugging one I-8000/I-87K series I/O module to expansion I/O channels, and hot-swap technique is supported. CAN-2000D series is palm-size stand-along DeviceNet slave device. It specially suits for distribution control system, and can be placed in a small space even in the case of machine. For more information about these devices, please refer to the following links.

DeviceNet master series
Parts of DeviceNet master series are I-87124 for PACs and PISO-DNM100 for PC based. In the parts, there is a DeviceNet master kernel inside. I-7565-DNM is also master product with USB interface. These products above are built-in 80MHz 186 CPU. Therefore, they can be used in high performance system. For economical solution, we provide the PISO-CAN card with the DeviceNet master lib.
