POINT
*1: When writing a program to the A1SNMCA-2KE,set the parameter for
main sequence program capacity to 2k steps or less.
Programs written with a main sequence program capacity setting of 3k
steps or over cannot work properly.
Checking between the AnSHCPU and a peripheral device will result in a
mismatch.
