5.1 MECHATROLINK-II Cyclic Transmissions
As a MECHATROLINK-I/MECHATROLINK-II slave, the SI-T exchanges control data and
I/O data with a control device, such as a controller. Communications with the controller are
executed by sending response data timed to the reception of command data for the local sta-
tion address from the controller in each transmission cycle. The formats for the command
and response data follow the specifications for the MECHATROLINK Inverter commands.
