TRANSMISSION DATA DESCRIPTIONS
The DIP SW located at the side of the module specifies each I/O module's data allocation (occupied data area).
For example, when the data areas are assigned as shown below:
Module 1
Module 2
Module 3
Module 4
Module 5
Module 6
Module 7
Then the I/O data are assigned as in the figures below:

[16*m] (m = cyclic expansion setting) data areas are available to the R3-NC3. Total data areas occupied by I/O modules must
be within this limitation.
