Explanation
16-bit or 32-bit word from slave to master with
bit-coded status messages
Explanation
Change of State/Cyclic Message is transmitted
by either the master or the slave. A Change of
State/Cyclic Message is directed towards a
single specific node (point-to-point). An
Acknowledge Message may be returned in
response to this message.
Common Industrial Protocol (CIP) is an
industrial protocol for industrial automation
applications. It is managed by ODVA.
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.
In the ODVA DeviceNet specification the word
'input' is used to describe data flow from a
device (such as FDNA-01) to the network.
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.
Every node on DeviceNet network has to have
a unique identifier. This node number is called
MAC ID (Media Access Control Identifier).
