Maximum number of input/output points when AnyWireASLINK master is used
1. Calculation of maximum number of input/output points
The maximum number of available input/output points is as follows when AnyWireASLINK master block is
used.
*1.
With regard to remote I/O of the AnyWireASLINK, input/output points set by the rotary switch of the
AnyWireASLINK master are assigned.
When using together with the CC-Link master, make sure that the total number of remote I/O points in
CC-Link and AnyWireASLINK master is 128 or less. For details, refer to FX
3U
-128ASL-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 units/blocks and AnyWireASLINK, the number of input/output points
and the total number of points are restricted.
*2.
When using 27 remote I/O points (8 points 3 + 2 1 point) shown above, assign 32 or more
input/output points using the rotary switch of the AnyWireASLINK master.
