6.3.2 Maximum number of input/output points when CC-Link master is used
1. Calculation of maximum number of input/output points
When CC-Link master block is used, the following maximum number of input/output points can be connected.
*1. 224 points when the FX
2N
-16CCL-M is used.
The number of CC-Link points is calculated by the formula "32 points
×
number of stations" even when
remote I/O stations having less than 32 points are used.
For details, refer to the manual of the CC-Link master block used.
2. Procedures for calculating number of input/output points based on example of system
configuration
For the main unit, input/output powered extension units/blocks and CC-Link remote I/O stations, the number
of input/output points and the total number of points are restricted.
