5. DeviceNet
DeviceNet is a network of multi-component industrial communications intended for communication between industrial controllers and devices (i / o) of inputs and outputs, with a maximum of 8 bits of data transfer capacity is very limited information.
Each controller is a device or network node forming a type Bus topology. Supports a total of 64 elements and communication speed may be 125, 250 or 500 Kbps depending on the distance of the cable 500, 250 and 100 meters respectively.
Accepts through its own network cable for those items with a limited consumption, and thus simplifying connections and outlets to the devices. DeciceNet system can be configured to work in a master-slave or a distributed architecture with point to point communication.
Feature table
| Network size | Up to 64 nodes |
| Net length | The distance varies depending on the selected speed
125 Kbps 500 m (1,640 ft)
250 Kbps 250 m (820 ft)
500 Kbps 100 m (328 ft) |
| Packet data | 0 to 8 bytes |
| Bus topology | Linear Bus (Trunk / step). With power and signal through the same cable. Bus Peer-to-Peer (peer to peer) with Multi-Cast (one-to-many). |
| Address bus | Multi-Master and Master / Slave special case; sample or change of status (based on exceptions) |
| System Features | Removal and replacement of network devices in the system fed |
