When the Read by Index command is used, the client of an SDO
(the MN) requests the REPL-01 to upload data to the client.
To address the objects, Indexes and Sub-Indexes are used. An
Index (0...65535) specifies and entry of the device object and a
Sub-Index (0...254) specifies a component of the device object
dictionary entry.
Ethernet POWERLINK Network Management (NMT) is node-
oriented and follows a master/slave relationship. REPL-01 is
administered as an NMT slave by the master.
Ethernet POWERLINK defines five categories of NMT services:
• NMT State Command Services
• NMT Managing Command Services (not supported)
• NMT Response Services
• NMT Info Services (not supported)

The MN controls the state of the CN via NMT State Command
Services. See section
more information.
NMT Response Services are used by the MN to query NMT
information from the CN, such as current state, error and setup
data. Ethernet POWERLINK specifies the following NMT
