CIP™ Common Industrial Protocol (CIP) is an
industrial protocol for industrial automation
applications. It is managed by ODVA.
EDS File Electronic Data Sheet (EDS) file identifies the
properties of the device to the DeviceNet
Scanner. Each type of drive and application
program requires its own EDS file.
Input In the ODVA DeviceNet specification the word
‘input’ is used to describe data flow from a
device (such as FDNA-01) to the network.
I/O assembly selection Smart networked devices (like FDNA-01) can
produce and/or consume more than one I/O
value. Typically, they 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.
MAC ID Every node on DeviceNet network has to have
a unique identifier. This node number is called
MAC ID (Media Access Control Identifier).
