*1 Each memory capacity for the programmable controllers 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.
