Explanation
Device Level Ring.
DLR network is a single-fault tolerant ring network
topology intended for interconnection of automation
devices. FENA-21 supports DLR.
The Electronic Data Sheet (EDS) file identifies the
properties of the device to the EtherNet/IP client. Each
type of drive and application program requires its own
EDS file.
In the ODVA EtherNet/IP specification the word 'input' is
used to describe data flow from a device (such as the
adapter module) to the network.
Smart networked devices (like FENA) can produce
and/or consume more than one I/O value. Typically,
they will produce and/or consume one or more I/O
value, as well as status and diagnostic information.
Each piece of data communicated by a device is
represented by an attribute of one of the device's
internal objects.
Communicating multiple pieces of data (attributes)
across a single I/O connection requires that the
attributes be grouped or assembled together into a
single block.
ODVA stands for Open DeviceNet Vendor Association.
ODVA is an independent organization that promotes
interoperability between different manufacturers'
EtherNet/IP products. ABB is an Associate Member at
ODVA.
In the ODVA EtherNet/IP specification the word 'output'
is used to describe data flow from the network into a
device (such as the adapter module).
