Digital in- and outputs
7.3.5 Digital
noise filter (di.03), fast digital noise filter (di.23)
The digital
noise filter
reduces the susceptibility to interferences on the digital inputs. Only hardware inputs can
be filtered. Each input has a separate filter counter that counts up at active input and down at inactive input.
The output of the filter is set on reaching the filter time and reset when zero is reached.
Parameter Setting range Resolution
di.03 0...127 ms 1 ms
di.23 0...31.75 ms 0.25 ms
Priority of the filter times: The larger of the two times is used.
7.3.6 Inversion of Inputs (di.04)
With parameter di.04 it can be adjusted whether a signal is 1- or 0-active (inverted). The parameter is bit-coded,
i.e. the value corresponding to the input mut be entered. If several inputs shall be inverted, then the sum is to
be formed. (Exception: An inversion of the control release remains without function).
7.3.7 Delay activation / deactivation digital inputs
40 I1 ON delay di.41 I1 OFF delay
di.42 I2 ON delay di.43 I2 OFF delay
di.44 I3 ON delay di.45 I3 OFF delay
di.46 I4 ON delay di.47 I4 OFF delay
di.48 IA ON delay di.49 IA OFF delay
di.50 IB ON delay di.51 IB OFF delay
di.52 IC ON delay di.53 IC OFF delay
di.54 ID ON delay di.55 ID OFF delay
Value range: 0 (off) ... 32.00 s; Resolution 0.01s; Default value : 0 (off), not set-programmable
Function:
The function can be switched off with the value di.40 – 55 = 0.
The ON delay starts with the positive edge of the input, the OFF delay with the negative edge.
In the following example I1 and I2 are first switched individually and then simultaneously.
The four required times are different adjusted.
