Total number of input/output points of the CPU module and I/O modules
Count the total number of input/output points of the CPU module and I/O modules.
To obtain the total number of input/output points, count the input points (X0 and more) and output points (Y0 and more) of the
CPU module and I/O modules.
For details of the number of input/output points by models, refer to the following.
Number of occupied input/output points of intelligent function modules
Count the number of occupied input/output points of intelligent function modules.
The number of occupied input/output points per module is 8.
For details on the number of occupied input/output points by models, refer to
Page 47 Intelligent function module.
Calculation of the number of remote I/O points
If the master module of the network is used, calculate the number of remote I/O points connected on the network.
The total number of remote I/O points must not exceed 384 points.
The maximum number of remote I/O points differs according to type of the network.
Precautions
• When CC-Link IE field network Basic is used, remote I/O points that are used in CC-Link IE field network Basic are
occupied, and then remote I/O points of the intelligent function module are occupied. For information on CC-Link IE field
network Basic, refer to
CC-Link IE Field Network Basic Reference Manual.
• When using CC-Link master (FX3U-16CCL-M) and AnyWireASLINK master (FX3U-128ASL-M) together, connect FX3U-
128ASL-M on the left side. In the FX5UC CPU module, FX3U-16CCL-M parameters are set up by PLC program and will
occupy up to 256 remote I/O points. Therefore, the remote I/O points of FX3U-128ASL-M that is connected to the right side
may be less than 128 points when FX3U-16CCL-M is connected to the left side.
Ex.
When input/output points are 160 points, FX3U-16CCL-M is connected to the left side of FX3U-128ASL-M, and 256 points of
remote I/O points to be used with FX3U-16CCL-M are occupied: 512 points - 160 points - 256 points = 96 points
Remote I/O points that can be used with FX3U-128ASL-M are 96 points or less.
Ex.
When input/output points are 160 points, FX3U-16CCL-M is connected to the right side of FX3U-128ASL-M, and the total
number of remote I/O points to be used with FX3U-128ASL-M is 128 points: 512 points - 160 points - 128 points = 224 points
Remote I/O points that can be used with FX3U-16CCL-M are 224 points or less.
