CAN

Controller Area Network (CAN) is widely used in automotive and industrial automation applications and is the basis for communicating with CANopen and DeviceNet protocols. Contemporary Controls makes network interface modules (NIMs) and bus extenders for this rugged technology.  NIMs are available to link ISA, PCI and PC/104 controllers to a CAN network with either a CANopen or DeviceNet physical layer.  Extend-a-Bus allows CAN-based networks such as DeviceNet to expand beyond their theoretical geographic limit without loss in performance.
