9.11.2 Setting the point mode (relationship between I/O numbers, station numbers and
point mode)
1. Assignment of I/O numbers
The I/O number is not affected by the point mode setting.

16-point mode
In the case of
4-point mode
2. Number of occupied stations
The station number of each remote station changes depending on the point mode selection (4-point mode or
16-point mode).
With up to 64 remote stations, more I/O points are available in 16-point mode since I/O modules with more
than 4 I/O occupy multiple stations in 4-point mode.
