[310] Analog hysteresis

Type
% Input value
I1
I2 % Variable hysteresis
b Start
I3
I4 b Master Reset
Description:
Signal (status-controlled) at I3 saves actual value at I1. The hysteresis values I2 (variable) and
P1 (constant) are added to and subtracted from the saved value. If the value of I1 is within the
hysteresis, the saved value is output. If the value of I1 is outside of the hysteresis, the current
value of I1 is output.
If the start input I3 is set, the input value I1 is maintained (F = I1).
I1 > F + (I2 + P1)
I1 < F - (I2 + P1)
F - (I2 + P1) < I1 < F + (I2 + P1)
Master Reset sets output O1 to FALSE.
If Master Reset is reset, the process must be started again via I3.
Output A = f(input E)
I3 I4 Function
1 0 Keep I1 at O1 constant.
x 1 Set O1 to FALSE.
Note:
Percentages [%] have two decimals.
For example: Value 12345
