|ArdweeNET is a medium-speed control
network designed to monitor and control devices in hobby, commercial
or light-industrial environment. It is a multi-master point-to-point
protocol using a redundant-ring topology that allows all nodes to transmit
frames when they please.|
ArdweeNET is completely open source, both
hardware and software.
Some of the main features are...
- Open design, no royalties, licensing fees or costs for intellectual
property. Creative Commons and/or GNU licenses will apply.
- Up to 254 nodes per network, unlimited IO points per node.
- Up to 1200m (4000') between nodes, maximum theoretical network
length of 300km.
- Nodes are Arduino software compatible.
- Multiple networks easily connected with wireless or other link
- Implements a "publishing and subscribing" model, nodes
publish at will and subscribers act on the published data.
- Very fault-tolerant redundant-ring topology.
- Physical level can use any medium but RS-485 is currently defined.
- Rogue applications, short circuits, cut wires cannot kill the
- Eight-wire CAT5 cable and RJ45 8/8 modular jacks. Wiring includes
power and data signals.
- Nodes can use local power or be powered from the network.
- Data rate variable up to 1Mbps.
- Frames size fixed at 16 bytes with a payload of 10 bytes.
- Large data packets automatically split into multiple 16-byte frames.
