KNX 4 channels binary input interface
7 . parameter Setting DeSCription in the etS (continued)
7 .5 parameter window“preset Channel a~D” (continued)
7 .5 .2 Separately adjustable working mode for binary input
(continued)
7 .5 .2 .5 Switching sequence (continued)
parameter “function on operation”
The parameter is only visible in the switching sequence “Sequentially
on/off (several push buttons)”. It can be set whether an operation of the
push button switches up or down a level.
Options: Switch upwards
Switch downwards
The implement direction of the parameter “Switch upwards” is “000-
001-011-111”, the implement direction of the parameter “Switch
downwards” is “111-011-001-000”.After the bus voltage recovery, the
current value is 000, if the parameter “Switch downwards” is selected,
the effect will be invisible when operation, then it is possible to
operation after switch up a few levels by the object “level increment/
decrement, X”.
parameter “Sequence is…”
This parameter indicate the manage process of switching sequence.
parameter “Debounce time/min time”
This parameter is used to set the debounce time. Debouncing prevents
unwanted multiple operation of the input, e.g. due to bouncing of the
contact.
Options: 10ms/20ms/……/150ms/Min. operation
The “Min. operation” can be set in fig.5.8.
7 .5 .2 .6 Counter
Parameter window “Counter, X” can be shown in Fig. 5.14. It is visible
when the input is operated with the function “counter”.
Using the “Counter” function, the device is able to count the number of
pulse edges at the input. A “differential counter” is therefore available
if required in addition to the standard counter. Both counters are
triggered by counting pulses but otherwise operate independently of
each other.
The data width which has been selected for both counters can be set to
same or different.
The function of differential counter is similar with the main counter.
The different is that the differential counter can reset the counter value
(count from the initial value) and stop counting after overflow via the
bus. The parameters of main counter can be set in fig. 5.14(1) and fig.
5.14(2). The parameters of differential counter can be set in fig. 5.14(1)
and fig. 5.14(3). The parameters set as follows:
Fig.7.14(1) Parameter window "Counter, X"
parameter “Debounce time/min time”
This parameter is used to set the debounce time. Debouncing prevents
unwanted multiple operation of the input, e.g. due to bouncing of the
contact.
Options: 10ms/20ms/……/150ms/Min. operation
The "Min. operation" can be set in fig.5.8.
parameter "enable differential counter"
The parameter set whether enable the differential counter.
Options: Yes
No
If this parameter is set to "yes", the parameter window fig. 5.14(3) is
displayed.
7 . parameter Setting DeSCription in the etS (continued)
7 .5 parameter window“preset Channel a~D” (continued)
7 .5 .2 Separately adjustable working mode for binary input
(continued)
7 .5 .2 .6 Counter (continued)
parameter “pulse detection on”
The parameter set how the input pulse is generated.
Options: Closing contact (rising edge)
Opening contact (falling edge)
Both (rising and falling)
If “Closing contact (rising edge)” is selected, the input pulse is only
generated with a closing contact (rising edge).
If “Opening contact (falling edge)” is selected, the input pulse is only
generated with a opening contact (falling edge).
If “Both (rising and falling)” is selected, the input pulse is generated with
a opening contact (falling edge) and a closing contact (rising edge).
parameter “mode of counter”
The mode of counting of the counter is set with this parameter.
Options: 1
Manual set
If “1” is selected, the counter value is incremented by one with
generated a input pulse;
If “Manual set” is selected, the following two parameters appear.
parameter “Divider: number of input pulse for one counter step
[1…10000]”
The parameter is visible if the option manual set has been selected with
the parameter mode of counter. It is used to set the number of input
pulses required to generate a counter pulse for the main and differential
counter. For example, the counter states are incremented by 1 after 5
input pulses.
Options: 1 … 10000
parameter “factor: one counter step changes counter value by
[-10000…10000]”
The parameter is visible if the option manual set has been selected with
the parameter mode of counter. It is used to set the level of change on
the counter state with each counter pulse for the main and differential
counter.
Options: -10000…10000
Negative entry e.g. -5, defines a decrementing counter, e.g. -100„0.
Positive entry e.g. 10, defines an incrementing counter, e.g. 0„100
parameter “Send object values after voltage recover”
The parameter set whether the device sends the object value
“Mcounter: counter value, X” on the bus after bus voltage recover. If the
differential counter has been enabled, it also sends the object value
“Dcounter: counter value, X” on the bus.
Options: Yes
No
The main and differential counters are reset to the starting value in the
bus voltage failure.
