2. Terms and Definitions
Term Explanation and Definition
Master/Slave A master is a unit that controls the DeviceNet communications.
Amaster 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.
