6.3 Number of Input/Output Points and Maximum Number of Input/Output Points
6.3.3 Maximum number of input/output points when AS-i master is used
1. Calculation of maximum number of input/output points
When AS-i system master block is used, the following maximum number of input/output points can be
connected.
*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 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 powered extension units/blocks and AS-i system, the number of input/output
points and the total number of points are restricted.
