PCI, NI-DNET Supported, 1-Port, DeviceNet Interface Device—The PCI-DNET is a high-speed DeviceNet Interface for developing applications with the NI‑Industrial Communications for DeviceNet driver. DeviceNet is based on the controller area network (CAN) physical layer and increases strength and interconnectivity by specifying various parameters, such as the required cable length, connectors, and baud rates. The DeviceNet specifications are managed by OVDA, Inc. You can program the PCI-DNET to add high-performance master/scanner or slave capabilities to DeviceNet networks.
