*1 I/O processing: during refresh and LD instruction execution
*2 The number of the actual I/O points is the same as the AnS series, but this model has 2048
points of I/O device for each CPU (X/Y0 to X/Y7FF). The added I/O devices can be used for
MELSECNET (/B), MELSECNET/MINI, or CC-Link.
*3 The comment points for comments that can be stored in the CPU module is 1600 points,
while up to 3648 points of comment can be created using the GPP function.
