 When the source data’s highest bit (16 bits: b15,32 bits: b31) is 1, it is seemed to negative
number.
 The comparison of32 bits counter should use32 bits instruction. If using16 bits instruction,
the program or operation will be error.
Example: forbid the outputs when it reaches the certain time. In the below program, when the
date is June 30
th
, 2012, all the outputs will be disabled. The password 1234 is stored in
(D4000, D4001). When the password is correct, all the outputs are enabled.
LD SM0 //SM0 is always ON coil
