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.
Maximum number of
input/output points
384 points
Maximum number
of points
controllable on
system
(A): Number of input/output points of main unit
(B): Number of input/output points of input/output
powered extension units
(C): Number of input/output points of input/output
extension blocks
*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 having less than 32 points are used.
For details, refer to FX
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.
