Change of State/Cyclic Message
The 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.
Communication Module
Communication Module is a name for a device (e.g. a fieldbus
adapter) through which the drive is connected to an external serial
communication network (e.g. a fieldbus). The communication with
the communication module is activated by a drive parameter.
EDS File
The 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 the RDNA-01) to the
network.
I/O Assembly selection
Smart networked devices (like the RDNA-01) 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.
