TRANSCEIVER
DeviceNet is a digital multidrop network that connects actuators,
sensors, and a broad range of industrial automation systems.
DeviceNet is managed by the Open DeviceNet Vendor Association
(ODVA ) and is accepted by international standards bodies around
the world, with a large number of companies offering DeviceNet
products.
The Communications and Information Protocol (CIP™) is a
communications protocol for transferring automation data
between two devices. DeviceNet is a combination of CIP™ (for
upper layers of the network) and the CAN physical layer for
the data link layer. DeviceNet allows up to 64 nodes on a single
network, with node addresses ranging from 0 to 63. DeviceNet
supports 125 kbps, 250 kbps, and 500 kbps data rates and supports
master and slave as well as peer-to-peer communication. The
ADM3052 can be used as the CAN physical layer transceiver for a
DeviceNet implementation. Refer to the AN-1123 Application
Note for a CAN implementation guide.
DeviceNet supports both isolated and nonisolated physical layer
design of devices. An isolated design option allows externally
powered devices (for example, ac drive starters and solenoid valves)
to share the same bus cable. DeviceNet requires the support of
the standard industrial voltage range from 11 V dc to 25 V dc.
The ADM3052 employs Analog Devices iCoupler technology,
combines a 3-channel isolator, a CAN transceiver, and a linear
regulator into a single package. Isolated power is supplied to the
bus side of the ADM3052 by an isolated 24 V supply across the bus.
The internal regulator provides the 5 V supply required internally
by the CAN transceiver. The logic side of the ADM3052 requires
a single 3.3 V or 5 V supply.
