2. Terms and Definition
Ter ms Explanation and Definition
Master/slave A master is a unit that manages the DeviceNet communications.
A master sends output data to multiple slaves and receives input data from
the slaves.
Slaves receive output data that are sent from the master, and send input
data to the master.
At least one master is required for DeviceNet communications.
EDS file A file that contains each DeviceNet slave's I/O points and parameters that
can be set via DeviceNet.
Node address
(MAC ID)
An address that identifies a unit connected to a DeviceNet network.
With DeviceNet, a MAC (Media Access Control) ID is used as a node
address. Thus, a node address is a MAC ID.
Scan list A scan list is used to register slaves with which a master communicates in
DeviceNet remote I/O communications. A master communicates with the
slaves based on the scan list settings.

value and other data are displayed
(red).
RUN key Runs the Inverter. Take note that this
key is enabled only when the RUN
command destination is the Digital
Operator.
STOP/RESET
Key
This key decelerates the Inverter to a
stop. (Although the STOP/RESET key is
enabled even when a RUN command is
issued to a destination other than the
Digital Operator (factory default), it can
be disabled by a Setting (b087).)
If the Inverter is already tripped, the trip
will be reset (return from the tripping).

beginning of the next function group.
Data is displayed: Cancel the setting
and return to the parameter display.
Individual input mode: Move the blinking
digit to the left.
