Integrated Motion on an
EtherNet/IP Network Integrated motion on an EtherNet/IP network sets the EtherNet/IP
networking technology apart from the other industrial Ethernet networks.
EtherNet/IP modules with integrated motion on the EtherNet/IP network
combine the requirements of deterministic real-time motion control applications
with standard unmodified Ethernet that provides full compliance with the
Ethernet standards IEEE 802.3 and TCP/IP. This supports the use of standard
Ethernet components and infrastructure without the use of special switches or
gateways.
Integrated Motion on the EtherNet/IP network accomplishes this by
encompassing a set of application profiles that let position, speed, and torque
loops to be set in the drive. With the addition of the CIP Sync technology
multiple axes can be coordinated for precise, coordinated motion control
applications.
Integrated motion on the EtherNet/IP network uses time-stamped data along
with its simple timing model to eliminate hard synchronization constraints
between the drive and the controller. Real-time data values are adjusted at the end
device at the time the data is applied; no need to hard schedule the network
traffic.
In addition, integrated motion on the EtherNet/IP network has the flexibility to
handle different types of drives and time synchronization requirements. The
same network connection can be used for both a high performance servo drive
with precise synchronization requirements, and a low performance Volts/Hertz
drive with no time synchronization capability.
