MAC ID
Every node on DeviceNet network has to have a unique identifier.
This node number is called MAC ID (Media Access Control ID).
ODVA
ODVA stands for Open DeviceNet Vendor Association. ODVA is
an independent organization that promotes interoperativity
between different manufacturers DeviceNet products. ABB is an
Associate Member at the ODVA.
Output
In the ODVA DeviceNet specification the word ‘output’ is used to
describe data flow from the network into a device (such as the
RDNA-01).
Parameter
A parameter is an operating instruction for the drive. Parameters
can be read and programmed using the drive control panel, or
through the RDNA-01 module.
Poll Message
Most DeviceNet Scanners as well as the RDNA-01 support two
different data services. These are Poll and Change of State/Cyclic
messages.
The Poll Command is an I/O Message that is transmitted by the
Master. A Poll Command is directed towards a single, specific
Slave (point-to-point, RDNA-01 always acts as a Slave). A Master
must transmit a separate Poll Command Message for each of its
Slaves that is to be polled. The Poll Response is an I/O Message
that a Slave transmits back to the Master when the Poll Command
is received.
RDNA-01 DeviceNet Adapter module
The RDNA-01 Adapter module is one of the optional fieldbus
adapter modules available for ABB drives. The RDNA-01 is a
device through which an ABB drive is connected to a DeviceNet
serial communication bus.
