[5] Fieldbus Communication Command 2
Even though it is available to have the fieldbus and data input and output domains set in Fieldbus
Communication Command, the data domains available for setting was fixed assignment.
In RCON-LC, the maximum number of the controllable axes was revised to 16 axes and in
MCON-LC it has been more than doubled from six axes. Due to this, when FIeldbus
Communication Command is used, the data size for one axis has decreased. By setting Fieldbus
Communication Command 2 that is available for setting the same or higher size data domains
compared to the exiting, solves the data size issues.
Shown below is an example of how to describe the command.
