Overview
1.2 System Configuration
Connect the MECHATROLINK-III cable to the MECHATROLINK port of the Adapter Unit to connect the
Adapter Unit to a MECHATROLINK-III network. Also connect a PC to the Ethernet port of the Adapter Unit.
Information from the devices connected to the MECHATROLINK-III network can be read out, and parameters
and data for the devices can be read or written, by using the PC connected to the Ethernet port.
The IP address of the Ethernet can be set by using the Adapter Tool.
The Adapter Unit and the Adapter Tool are connected through Ethernet, so a general purpose PC currently con-
nected in the network can be used to run the Adapter Tool.
The following diagram shows an example of the system configuration.
Connect the Adapter Unit at a terminal of the MECHATROLINK-III network.

Network)
• Since the Adapter Unit functions as the C2 master station in the network, the C1 master needs to support the
use of a C2 master. Only one C2 master can be connected in a MECHATROLINK-III system, so the
Adapter Unit cannot be used in conjunction with other C2 master stations.
• The Adapter Unit connects to the MECHATROLINK-III system by midstream association. For this reason,
the MECHATROLINK-III system in which this unit is connected must secure the free time for midstream
association within the transmission cycle. For details on the time required for midstream association, refer
to the “MECHATROLINK-III Protocol Specification” (Document No. MMATDEP020A). Download this
document from the MECHATROLINK Members' Association website.
