Distribution box for sensors
Molex
Provides communication mechanisms fulfilling a variety of needs that may be individually implemented or used all together in the same system
Brad DeviceNet by Molex is designed to be a low-cost-real time, device level bus architecture that connects sensors and actuators. Wiring and installation of automation devices is greatly simplified while the diagnostic information about the various I/O of the system is greatly enhanced. DeviceNet defines a standard device object-oriented software model that permits multi-vendor interoperability. If offers the user a variety of control architectures, giving the control designer the ability to choose either:
# highly distributed control
# semi-distributed control
# highly centralized control
DeviceNet is a digital, multi-drop network that connects and serves as a communication network between industrial controllers and I/O devices. Each device and/or controller is a node on the network. DeviceNet is a producer-consumer network that supports multiple communication hierarchies and message prioritization. DeviceNet systems can be configured to operate in a master-slave or a distributed control architecture using peer-to-peer communication. DeviceNet systems offer a single point of connection for configuration and control by supporting both I/O and explicit messaging. DeviceNet also has the unique feature of having power on the network.
DeviceNet is a CAN (Controller Area Network) based communication protocol that transmits a maximum of 8-bytes as a single message. Its primary usage is with digital I/O and non time-critical analog control. DeviceNet supports on-line node insertion and removal.
