1.8 Number of Input/Output Points and Maximum Number of Input/Output Points
1.8.3 Maximum number of input/output points when AS-i master is used
1. Calculation of maximum number of input/output points
The maximum number of input/output points available is as follows when the FX3UC-32MT-LT Ver. 2.20 or
later, FX
3UC-MT/D or FX3UC-MT/DSS and an AS-i master block are used.
→ For the method of calculating the number of I/O points, refer to Subsection 1.8.1.
*1. Up to 31 slaves can be connected to the AS-i system master block.
The maximum number is calculated by the formula "8 points × number of slaves" regardless of the
number of I/O points used on one slave.
For details, refer to the AS-i System User’s Manual.
2. Procedures for calculating number of input/output points based on example of system
configuration
For the main unit, input/output blocks and AS-i system, the number of input/output points and the total
number of points are restricted.
