DeviceNet is an ODVA™ device-level communication protocol for industrial automation. A DeviceNet network is an open, low-cost system link between industrial devices such as sensors and actuators and higher-level devices such as programmable logic controllers and PCs. DeviceNet networks use the network-independent protocol called Common Industrial Protocol (CIP) to provide its control, configure and data collection capabilities. Additional flexibility is offered via the network's ability to work with devices from multiple vendors - and, unlike other protocols, the user can add a power tape at any point (with a maximum power pair ampacity of 8 amps using Thick cable), allowing for redundant power supplies.
A DeviceNet network can support up to 64 nodes and the network end-to-end distance is variable, based on network speed. At 125 Kbps, the maximum network distance is up to 500m. At the highest speed, 500 Kbps, the maximum network distance is up to 100m. The bus topology is a trunkline-dropline linear bus.
Belden Offers an Extensive Cable Line Up
As an active member of ODVA, Belden provides an extensive line of DeviceBus® cables which are typically designated as either Class 1 (600V) or Class 2 (300V) “Thick,” “Thin,” or “Mid” cable. They can be used for either trunk or drop applications, dependent on the system speed and overall end-to-end distance.
Exceptional Performing DeviceBus Cables
Belden DeviceBus cables provide the following features and benefits:
- Full compliance with ODVA specifications
- TC-ER and PLTC-ER ratings are applicable on certain cables
- Data and power functionality in one cable
- Reduced cable and installation costs
- New Red jackets on products designating DeviceNet Safety (allows users to place safety devices on the same network as their standard controls)
- Full compliance with ROHS Directive
