Terms 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 A file that contains the I/O points of DeviceNet slaves 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 DeviceNet.
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.
