Signal mapper example

Task

The measured values of temperature and humidity as well as the status of the lighting in four rooms in an office building should be acquired and visualized with ibaQPanel.

The QPanel layout should be designed before the real input signals are available. Hence, signal mapper modules will be used for the data supply of the QPanel elements.

Implementation

1. Add a first signal mapper module and rename it (module name "Room_01").

2. In the general module settings click on the link Configure profiles.

3. Add a profile and rename it ("Room")

4. On the General tab of the profile decide which metadata should be adopted from the source signal and which should be retained by the profile. In this case, signal name and unit will be adopted from the source signal.

5. On the Analog tab define the analog values, which are needed for the visualization (RoomID, Temperature, Humidity).

6. On the Digital tab define the digital signals, which are needed for the visualization (LightON).

7. Close the Configure profiles dialog by <OK> and select the profile "Room" under Profile in the general module settings.

8. Together with the profile the module automatically gets its Analog and Digital tabs containing the defined signals. The source signals are not assigned yet.

9. Copy the signal mapper module three times and rename each of them, resulting in four modules "Room_01"..."Room_04". All four modules still have the same signal names.

10. Design the QPanel elements for the display and group them for one room. Then copy this group three times.

Link the QPanel elements of each room with their respective signals of the signal mapper modules "Room_01" to "Room_04". The input signals of the QPanel elements still have the same name (e.g. "Temperature") although they come from different modules.

11. If the source signals are available you can assign them to the signal mapper modules on the Analog and Digital tabs. Because we have configured in the profile that the signal name should be adopted from the source signal, the signal names of the signal mapper modules change correspondingly.
