In versions prior to 9.0.x.x the Selection Switch + was known as the Push-Button +, the functionality remains the same.
APPLICATION
An analogue value can be incrementally increased by pushbutton pressure by means of the program module selection key.
BASIC PROGRAMMING
With each pulse into the input +, the value at output AQ is increased by the value SI until the value of Max has been reached and then starts again at value Min.
If the input + held down and selected for longer, during this constant signal, several increases are performed at output AQ depending on the set repetition rate (parameter Rr).
The value range at output AQ can be defined by the two parameters Min (minimum value) and Max (maximum value).
The value at output AQ can be set directly via input P. For example, if the value 5 is applied to the input P, the value 5 is sent through to output AQ.
By a pulse from input R, output AQ is set to the default value (parameter D).
If input Dis is activated, the inputs are disabled. However, the block can still be operated via the user interface.
INPUTS
| + | Trigger pulse | With each pulse arriving at this input, AQ is increased by the value SI. |
| P | P | Sets the output to a certain value. |
| R | Reset | Set to pulse AQ to D. |
| Dis | Disable | Locks all inputs (child protection), can still be operated via the user interface. |
OUTPUTS
| AQ | Current counter reading | Incremented by SI with each pulse to the input (+). |
PARAMETERS
| Retention | Remanence | Activates the remanence of this building block. |
| Min | Minimum value | Sets the minimum value for AQ. |
| Max | Maximum value | Sets the maximum value for AQ. |
| SI | Increment | Value by which the output AQ should be increased to (+) at pulse. |
| Rr | Repetition | Defines the interval at which AQ is increased by SI as long as (+) is active. |
| D | Value to which the output is to be set at reset (R). |
