2.4 Topologies
The SVC Function Module uses MECHATROLINK-III communications to control slave devices.
You can connect the MP3000 and MECHATROLINK-III slave devices with cascade, star, or
mixed cascade/star topologies. This section describes these topologies.
2.4.1 Cascade Connections
Cascade connections allow you to connect one or more series of slave stations from the
MECHATROLINK-III communications port (CN6) on the MP3000.
Note: This connection example uses a transmission cycle of 3 ms.
