*1 Each memory capacity for the PLCs is the sum total of the parameters, T/C setting values,
program capacities, file registers, comment points, sampling traces and status latches. The
memory capacities are unchanged. The extension memories cannot be approved.
For the calculation method of memory capacity, refer to Section 4.2.2.
*2 I/O devices of the actual number of I/O points or later can be used as the MELSECNET/
10,MELSECNET(II)/B,MELSECNET/MINI or CC-Link.
