Item Description
1. The actual number of points that can be used is the total number of I/O points of the Control Unit and
the Expansion Unit.
2. The two pulse outputs, Y6 and Y7, are not available at the same time.
3. For C14 and C16 series, the hold type data are backed up by the internal capacitor. Back-up time for
them is 10 days at 25°C.

Note 3
Approx. 27,000 h (C24C, C40C, C56C, and C72C types)
Approx. 53,000 h (except C24C, C40C, C56C, and C72C types)

Note:
• Input response time can be
changed using the input time
filtering function as 1 ms, 2 ms, 4
ms, 8 ms, 16 ms, 32 ms, 64 ms
or 128 ms in 8 input units.
However, for E8 and E16 series,
the input response time is fixed
as 2 ms.
