5.8.2. DEVICENET
DEVICENET ( 30923 ) is a low-cost communications link that connects industrial
devices to a network, eliminating expensive hardwiring.
– It is based on a broadcast-oriented, communications protocol the CAN.
– The
CAN Protocol
was originally developed by BOSCH for the European
automotive market for replacing expensive wire harnesses with low-cost
network cable.
– The
CAN Protocol
has fast response and high reliability for applications like
anti-lock brakes and air bags.
DEVICENET also provides power to the network. This allows devices with limited
power requirements to be powered directly from the network.
– This reduces connection points and physical size.
– The maximum network size is up to 64 Nodes, with message data packets up
to 8 bytes.
