4. When PV reaches up to 2,147,483,647, the next PV will turn to -2,147,483,648. When PV reaches down to
-2,147,483,648, the next PV will turn to 2,147,483,647.

1. X10 drives M1200 to determine whether C200 is an addition or subtraction counter.
2. When X11 goes from Off to On, RST instruction will be executed, PV in C200 will be cleared to "0”, and the
contact will be Off.
3. When X12 goes from Off to On, PV in the counter will count up (plus 1) or down (minus 1).
4. When PV in C200 changes from K-6 to K-5, the contact of C200 will go from Off to On. When PV in C200
changes from K-5 to K-6, the contact of C200 will go from On to Off.
5. If you use MOV instruction, PMSoft or HPP03 to send a value bigger than SV to the present value register of C0,
next time when X1 goes from Off to On, the contact of counter C0 will be On, and its PV will equal SV.

3.8 Numbering and Functions of Registers [D]
3.8.1 Data Register [D]
A data register is for storing a 16-bit datum of values between -32,768 ~ +32,767. The highest bit is “+” or “-“ sign. Two
16-bit registers can be combined into a 32-bit register (D + 1; D of smaller No. is for lower 16 bits). The highest bit is
“+” or “-“ sign, and it can store a 32-bit datum of values between -2,147,483,648 ~ +2,147,483,647.
