*2 Maximum number of I/O points per system Connection is allowed as far as the following
condition is satisfied:
(Actual number of I/O points of PLC) + (Number of points occupied by special extension
blocks) + (Number of points occupied by FX
2N
-16CCL-M: 8) + (32 x Number of remote I/
O modules)
≤
128
Moreover, if connecting two or more FX
2N
-16CCL-M, the first master module can
connect to the “remote I/O modules” and “remote device modules” but subsequent
modules only connect to “remote device modules”.
*3 For details, refer to FX
2N
-64CL-M User’s Manual.
*4 The value depends on the switch setting (16, 32, 48, 64, 96 or 128 points).
*5 FX
2N
-32ASI-M must be supplied 70mA (at Typical 30.5V) from the AS-interface power
supply.
*6 The I/O control points of both the FX
2N
-32ASI-M and PLC CPU must not exceed 128
points. Therefore, there is a limitation in the number of units (number of slaves) which
can be controlled according to the I/O points recognized by the PLC's CPU (occupation).
Occupation I/O points: Each AS- i slave station occupies 4 CPU I/ O points.
