Standard specification parts (When the last two digits of the part number are alphabetical characters or the
second last digit is an alphabetical character and the last digit is numeric *Excluding C1 to C9) can’t be
used due to no safety function incorporated.
This chapter deals with special specification parts (When the last two digits of the part number are numeric,
the second last digit is numeric and the last digit is an alphabetical character, or the last two digits are C1 to
C9) with safety functions.
For details such as circuit constants in this chapter, refer to the reference specification (SX-DSV02468).
