Application Layer Specifications

The data format for the application layer conforms to the MECHATROLINK-II link com-
mand specifications. The SI-T/V7 has the following main commands and sub-commands.

The main commands are used in both the 17-byte and 32-byte modes for 
MECHATROLINK-II and with MECHATROLINK-I. The sub-commands can be used only 
when the 32-byte mode has been selected by means of pin 2 on DIP switch S1. If a conflict 
occurs between a request for a main command and a request for a sub-command, the request 
for the main command is processed. If either a main command or a sub-command is already 
being processed, the command being processed is given priority. If an INV_CTL main com-
mand and an INV_I/O sub-command conflict, the sub-command overwrites the main com-
mand. 

For details on command formats, refer to
