Possible applications:
−
Definition of reference values by means of two pushbuttons. If one of the two buttons is
pressed, the reference value is to be raised or lowered by an adjustable amount.
− Counting of (error) events. With each event, the counter counts up. The counter can trigger
other functions, such as reporting errors occurring too often.
Example: P1 = 6, P2 = 4
1) Master Reset sets output O1 to zero.
2) Three counting pulses up (each 100.00%/P1 = 100.00%/6 = 16.67%)
3) One counting pulse down. (100.00%/P2 = 100.00%/4 = 25%)
4) Four counting pulses up (each 100.00%/P1 = 100.00%/6 = 16.67%)
5) Two counting pulses up, limitation to 100.00%
6) Three counting pulses down. (each 100.00%/P2 = 100.00%/4 = 25%)
7) One counting pulse up (100.00%/P1 = 100.00%/6 = 16.67%)
8) One counting pulse down. (100.00%/P2 = 100.00%/4 = 25%)
9) Two counting pulses down, limitation to zero.
10) Master Set sets output O1 to 100.00%.
11) Two counting pulses down. (each 100.00%/P2 = 100.00%/4 = 25%)
Note:
P1 and P2 are limited internally to 100.00%. If a greater value is entered, this value is replaced
by 100.00%.
