*1. When seven 32-point type remote I/O stations are used, the number of CC-Link remote I/O points
reaches the maximum number.
The number of CC-Link points is calculated by the formula "32 points × number of stations" even when
remote I/O stations with less than 32 points are used.
For details, refer to the FX
2. Procedures for calculating number of input/output points based on example of system
configuration
For the main unit, input/output extension blocks and CC-Link remote I/O stations, the number of input/output
points and the total number of points are restricted.
