DeviceNetDeviceNet

DeviceNet is an open fieldbus standard, also based on the CAN protocol and standardized in IEC 62026 as well as EN 50325. Protocol specifications and the maintenance of the DeviceNet standard are overseen by the independent and open user organization ODVA (Open DeviceNet Vendor ­Association). DeviceNet uses the CAN specification on the lower layers of the ISO/OSI model (layers 1 - 4) with just a few limitations. On the upper layers (5 - 7), DeviceNet uses the Common Industrial Protocol (CIP) defined by the ODVA.
