The DeviceNet
network infrastructure is passive, making node functionality independent of physical location and the network it-
™
self inherently tolerant to individual lost node connections. Although the network infrastructure is passive, the network cable can
convey device power over the same cable with communication messages.
DeviceNet
systems require only a single point of connection for both configuration and control. This is because DeviceNet
™
ports both I/O (or implicit) messages, which typically contain time-critical control data, and explicit messages, in which the data field
carries both protocol information and specific service requests. DeviceNet
troller/device or distributed control architecture using peer-to-peer communication.
2.6 PROFINET I/O
PROFINET is an industry technical standard for data communication over Industrial Ethernet. It is designed for collecting data from,
and controlling equipment in industrial systems, with a particular strength in delivering data under tight time constraints.
PROFINET is standardized in IEC 61158 and IEC 61784.
PROFINET implements the interfacing to peripherals. It defines the communication with field connected peripheral devices. Its basis
is a cascading real-time concept. PROFINET defines the entire data exchange between IO-Controllers and IO-Devices, as well as pa-
rameter setting, and diagnosis. IO-Controllers are typically a PLC, DCS, or IPC. IO-Devices can be varied: I/O blocks, drives, sensors, or
actuators.
The PROFINET protocol is designed for fast data exchange between Ethernet-based field devices and follows the provider-consumer
model. Field devices in a subordinate PROFIBUS line can be integrated in the PROFINET system seamlessly via an IO-Proxy.
2.7 EtherNet/IP™
EtherNet/IP
("IP" stands for "Industrial Protocol") is an industrial Ethernet network managed by ODVA, Inc. (formerly Open Device-
™
Net Vendors Association, Inc.), a global trade and standards development organization.
EtherNet/IP
works on a TCP/UDP/IP based Ethernet network and uses the most widely deployed collections of Ethernet standards
™
to provide a broad range of applications in different industries that require high-speed and stability. Common applications include
factory automation, building automation, and process automation.
The typical EtherNet/IP
architecture includes a scanner and adapters. Data exchange is achieved between devices through an I/O
™
connection and explicit messaging. The EtherNet/IP
installed and configured with embedded switch technology over EtherNet/IP
Applicable networks include linear topology, ring topology, star topology, Ethernet, EtherNet/IP
The configuration can be set through USB or an interface.
