5.9 Counters
5.9.1 [450] Up/Down counter with analog output
Type Function Type Function
I1 b Up counter O1 % O1= counter I1 - counter I2
I2 b Down counter O2 % inverted output = -1
I3 b Master Set P1 i Steps up for 100.00%
I4 b Master Reset P2 i Steps down for 100.00%
Description:
−
Each positive edge at I1 increases the output value O1 by 100.00%/P1.
− Each positive edge at I2 reduces the output value O1 by 100.00%/P2.
− The output value is limited to the range 0.00% … 100.00%.
− Master Set (I3) sets the output to 100.00%. This input has priority over edges at I1 or I2.
− Master Reset (I4) sets the output to 0.00%. This input has priority over edges at I1, I2 and
Master Set I3.
