2. Terms and Definitions

Term Explanation and Definition

Master/Slave A master is a unit that controls 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 An EDS file is a file that contains the I/O points of DeviceNet slave units

and the parameters that can be set via DeviceNet.

Node address

(MAC ID) A node address is an address to identify 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.
