1.8.2 Maximum number of input/output points when CC-Link master is used
1. Calculation of maximum number of input/output points
The maximum number of available input/output points is as follows when the FX
3UC
-32MT-LT Ver. 2.20 or
later, FX
3UC
- MT/D or FX
3UC
- MT/DSS and CC-Link master block are used.
→
For the method of calculating the number of I/O points, refer to Subsection 1.8.1.
*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
2N
-16CCL-M User’s Manual.
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.
