Example of system configuration
Confirmation of system configuration validity
1) Number of connectable units to the main unit
There is no problem since only 1 unit can be connected to the main unit.
2) Maximum number of I/O points per system
384 points (FX
3U maximum number of input/output points) - 360 points = 24 points (remaining number of
I/O points)
In the configuration above, up to 24 I/O points or special function blocks corresponding to up to 24 points
can added.
3) Maximum number of connectable stations
There is no problem since no restrictions are violated.
Actual number of PLC I/O points 96 points
Number of points occupied by special function blocks 0 point
Number of points occupied by the FX3U-16CCL-M 8 points
32 points × Number of remote I/O stations 256 points
Total: 360 points
Remote I/O station 8 stations
The total number of stations:
Remote device stations + Intelligent device stations
8 stations
The total number of RX/RY points:
Remote device stations + Intelligent device stations
256 points
