Giới thiệu thiết bị giao thức DeviceNet
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.

Memory map of Remote I/O
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”.
Remote I/O Module and Unit DeviceNet
CAN-8×24 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-8×24 series and CAN-2000D series are the product size and the capabilities of expansion. CAN-8×24 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.
DeviceNet Series Common Features
- Comply with DeviceNet specification volume I, release 2.0& volume II, release 2.0
- Support Predefined Master/Slave Connection Set (Group2 Only Server)
- I/O operating modes: Polling, Bit-Strobe, Change of State/ Cyclic
- 2500Vrms photo couple isolation on the CAN side
- Jumper or DIP switch for 120Ω terminal resistor of CAN bus
- Watchdog inside

Card DeviceNet master
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.
