DeviceNet Solution December, 2003 This presentation document explains the R3.04 new features.

DeviceNet based on CAN (Controller Area Network) Technology What is DeviceNet ? DeviceNet is one of the major device-level networks for industrial automation. For more details, visit http://www.odva.org/ (ODVA: Open DeviceNet Vendor Association) DeviceNet based on CAN (Controller Area Network) Technology DeviceNet is one of the major Field bus and based on CAN. DeviceNet is popular in U.S.A. DeviceNet communicates mainly discrete devices. DeviceNet Solution

DeviceNet Configuration HIS ENG Typical hardware configuration ALD112 is connected to ALE111 ALE111 interfaces ALD112 by Modbus/TCP protocol. Redundant configuration is not supported. Vnet FCU SyCon ALE111 Ethernet Switching HUB ALD112 DeviceNet This is a DeviceNet System Configuration. SyCon is the DeviceNet configuration tool. And target devices are ALD112, DeviceNet and DeviceNet devices. SyCon support debug function for DeviceNet,too. SyCon can be installed in the same PC where the CS3000 System builders are installed. When Sycon is installed to the same PC of the CS3000 system builders, the operating system of the PC should be Windows 2000 Server. To prevent from collision of communication, it is recommended to use switching hub and to segregate the Ethernet network in to independent ALD112-Sycon and ENG-HIS Ethernet networks. SyCon : DeviceNet Configuration Tool from Hilscher SyCon can be installed in the same PC where the CS3000 ENG are installed.

The CAN bus is a reliable bus used in the auto sector. (3)Bus access method The device that started communicating first on the bus has the priority to keep communicating. When there are two devices that start communicating at the same time, the device with priority can keep communicating by looking at the pattern of 11 bits (packet ID) at the head of the communication frame. This is CSMA/NBA (Carrier Sense Multiple Access with Non-destructive Bitwise Arbitration）Method (4)Device profile EDS (Electric Data Sheet) is defined in the DeviceNet specification. This is an easy file format, and other venders can acquire the specific information on the product. Confidential DeviceNet Solution
