*1 : I/O processing: during refresh and LD instruction execution
*2 : Actual I/O points are the same as the AnS series, but this model has 2048 points of I/O device
for each CPU (X/Y0 to 7FF). The added I/O device 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.
The dissimilarities between the A1SHCPU and A1SCPU are as follows :
Max. 8192 points (R0 to 8191)
There are some restrictions.
Year, month, day, hour, minute, day of week (Automatic leap year calculation)
