DeviceNet bus connector 5-pin 7/8 aviation plug

DeviceNet bus connector 5-pin 7/8 aviation plug

DeviceNet is an open fieldbus based on CAN bus, which is mainly used in automation technology. DeviceNet was originally developed by Allen Bradley. In order to build better systems in this market, DeviceNet was later handed over to ODVA (Open DeviceNet Vendors Association) as an open standard. DeviceNet is standardized on the European EN50325 standard and is designed as a powerful sensor-actuator network. For this purpose, Germany's KUNBUS provides a variety of products with different forms and interfaces.

The DeviceNet protocol is developed on the basis of the CAN protocol. It is considered an open fieldbus standard according to the European standard EN50325 and is mainly used in automation technology to connect sensors and actuators. In the same way as Ethernet/IP and Controlnet, DeviceNet can be considered part of the CIP network family. As a result, these three modern networks in industrial communications have a common application layer (CIP is the Common Industrial Protocol). While Ethernrt represents routing level and Controlnet represents unit level, DeviceNet is available at field level. DeviceNet is object-oriented according to the producer-consumer process design, where clients and servers can be producers and/or consumers, and DeviceNet devices are master or slave devices.

DeviceNet installations use DeviceNet cables, which have two signals for data transmission (CAN-L, CAN-H), and two lines for the bus station. A maximum of 64 bus participants can exchange data in the DeviceNet network, with baud rates of 125, 250 or 500 kb/s available. During installation, the cables are connected with a 120 ohm terminating resistor. Therefore, external power supply or bus power are options for bus stations.

The role of DeviceNet terminal resistor

DeviceNet_network is a fieldbus network protocol based on Controller Area Network (CAN). In the DeviceNet network, the terminal resistor plays the role of compensation and protection for signal transmission. The function of the terminal resistor is to eliminate signal reflection and interference and ensure the signal transmission quality.
