8. EXECUTING THE RING COUNTER FUNCTION

8 - 4

8.1.2 Count range

As shown below, the count range of the ring counter function differs depending on the
relationship between the preset value, ring counter value, present value and counting
mode (up/down count).

(1) If preset value present value ring counter value

The following operation is performed if the ring counter function is executed at the
preset value of 0, ring counter value of 2000, and present value of 500.

1) In up count, the present value returns to the preset value (0) as soon as it is

counted up to the ring counter value (2000)

2) In down count, the present value returns to the maximum value (16777215)

when it is counted down to the preset value (0).
Then, when the present value is counted down to the ring counter value (2000),
it returns to the preset value(0).

(2) If preset value ring counter value present value

The following operation is performed if the ring counter function is executed at the
preset value of 0, ring counter value of 2000, and present value of 3000.

1) In up count, the present value returns to the minimum value (0) when it is

counted up to the maximum value (16777215).
Then, when the present value is counted up to the ring counter value (2000), it
returns to the preset value(0).

POINT

• Do not write the preset and ring counter values during execution of the ring

counter function. If they are written, the ring counter operation may not be
performed properly.

• Note that the ring counter function is not activated when the following

expression is satisfied.

Ring counter cycle 10-link scan time+2-sequence scan time
