Application “1-button step switch”
Different switching processes are triggered with each new actuation of the 1st or 2nd
button.
For example:
■
First actuation (2nd button) switches on lamp 1.
■
Second actuation (2nd button) switches lamp 1 off and lamp 2 on.
■
Third actuation (2nd button) switches lamp 2 off and lamp 3 on.
■
Fourth actuation (1st button) switches lamp 3 off and lamp 2 on.
■
Fifth actuation (1st button) switches lamp 2 off and lamp 1 on.
■
etc.
Up to five switching levels can be activate.
The application differentiates between whether the 1st or 2nd button was actuated.
Depending on the setting, one lower or one higher level can be switch to.
12.13.1
Common parameter – Number of objects
Options
1 to 5
The application can switch up to five levels. For every level, its own 1-bit communication
object is available. The number of the levels is specified via the "Number of objects"
parameter.
12.13.2
Common parameter – Evaluation period (sec)
Options
Time input from 2 to 5 seconds
The application can differentiate between a single, double, triple, quadruple or quintuple
operation of the button. If the button is to recognize a multiple operation, then the button
must be operated multiple times in a relatively short period of time. The period during
which the button evaluates a multiple operation will start anew after each operation.
12.13.3
Extended Parameter – Duration of long operation (ss:ms)
Options
Time input from 0.3 to 2.5 seconds
A differentiation can be made between a short or long operation of the button. With a
short operation of the button, the next level forward is switch to in each case. With a long
operation, the first level is activated. Thus, with a long button press a jump back from
every position to the first level is possible, without having to run through the remaining
levels.
Via the "Duration of long operation", the time is specified from which a long button press
is recognized, and the object values are reset. The first level must be set again with a
press of the button. Any time from 0.3 to 2.5 seconds can be set. A typical value after
which a jump-back to level 1 is set at 0.4 s.
