Number Description
1)
The present counter value, 0, is stored in CH
Periodic pulse count present
value (Un\G18, Un\G19, Un\G50, Un\G51).
2)
The present counter value, 200, is stored in CH
Periodic pulse count present
value (Un\G18, Un\G19, Un\G50, Un\G51).
The value 0, which had been stored in CH
Periodic pulse count present value
(Un\G18, Un\G19, Un\G50, Un\G51), is then stored in CH
Periodic pulse count
previous value (Un\G16, Un\G17, Un\G48, Un\G49).
3)
The present counter value, 20, is stored in CH
Periodic pulse count present
value (Un\G18, Un\G19, Un\G50, Un\G51).
The value 200, which had been stored in CH
Periodic pulse count present
value (Un\G18, Un\G19, Un\G50, Un\G51), is then stored in CH
Periodic pulse
count previous value (Un\G16, Un\G17, Un\G48, Un\G49).
4)
The present counter value, 100, is stored in CH
Periodic pulse count present
value (Un\G18, Un\G19, Un\G50, Un\G51).
The value 20, which had been stored in CH
Periodic pulse count present value
(Un\G18, Un\G19, Un\G50, Un\G51), is then stored in CH
Periodic pulse count
previous value (Un\G16, Un\G17, Un\G48, Un\G49).
5)
The present counter value, 80, is stored in CH
Periodic pulse count present
value (Un\G18, Un\G19, Un\G50, Un\G51).
The value 100, which had been stored in CH
Periodic pulse count present
value (Un\G18, Un\G19, Un\G50, Un\G51), is then stored in CH
Periodic pulse
count previous value (Un\G16, Un\G17, Un\G48, Un\G49).
6)
The periodic pulse counter function is performed regardless the on/off status of
CH
Count enable command (Y4, YC).
7)
While the periodic pulse counter function is performed, "1" is stored in CH
Sampling/periodic counter flag (Un\G11, Un\G43).
