Block Weather station
Block Weather station| The control element shows the values of a
weather station and is the user interface for the
function block Block
Weather station. The control element must be linked to this
function block. To do so, right-click the element in the Studio and
select the function block. The tile shows the temperature, the current weather symbol, the wind speed and the brightness. Four dots at the bottom indicate whether a wind, rain, frost or heat alarm is present. The gear symbol at the top right opens the dialog with all values. |
| The dialog shows all readings, the daily
values and the state of all monitoring functions. Values whose input is
not connected on the function block (humidity, air pressure, wind
direction, rain amount) are not shown. The lower area shows for every monitoring function whether it is currently active. If a monitoring function is switched off, "off" is shown next to it. Tapping a field switches the corresponding monitoring function on or off. A sensor fault and a running test mode are shown in the header of the dialog. On a sensor fault the cause is shown next to it: |
| Signal at the fault input | The weather station reports the fault itself through the fault input of the function block. |
| Reading implausible | The named reading is permanently outside the reasonable range. Usually the data type of the address is wrong. |
| Values are not updated | No reading has changed within the configured time (or the heartbeat has not toggled). |
Three symbols are available in the title bar: |
| Gear | Settings of all limits and times. |
| List | Alarm log with the most recent events. |
| Chart | Statistics of the weather trends. The symbol can be hidden in the properties of the control element. |
| The settings are arranged in groups and
can be scrolled with the finger or the mouse wheel. All values are
stored in the controller and are retained after a restart. Next to a limit value there is a second button showing the current reading. Clicking it applies the reading as the limit. This makes it very easy to set the shading thresholds in particular: simply wait until the desired brightness is reached and apply the value. The values are only transferred to the controller with "Save". |
| Monitoring | Switches the respective monitoring function on or off. If it is switched off, the corresponding output goes to 0 immediately. |
| Alarm above / below | Limit at which the alarm is triggered. |
| Switch-on delay | The limit must be exceeded for this long before the alarm is set. Prevents alarms caused by short peaks. |
| Reset time | The value must stay below the limit continuously for this long before the alarm is cleared. If the limit is exceeded again in between, the time starts over. |
| Hysteresis | Distance between the switch-on and the switch-off point. For brightness the hysteresis is given as a percentage of the limit. |
| Evaluate rain amount | Generates the rain alarm from the rain amount in mm/h instead of the rain signal. Only useful if the rain amount is connected on the function block. |
| Only with precipitation | The frost alarm is only triggered when rain is reported as well. Protects awnings against icing without retracting unnecessarily in dry cold. |
| Input is a bit | The twilight input is evaluated as a switching bit instead of a brightness value. |
| Sensor failure after | If no reading changes within this time, the weather station is considered faulty. 0 switches the monitoring off. |
| Safe position | On a sensor fault the wind and rain alarms are forced. This protects the shading if, for example, a sensor cable is broken. |
| Repeat alarm every | Pending alarms are sent again at this interval. This way the message reaches the actuator even if a telegram is lost. 0 switches the repetition off. |
| Plausibility check | Readings outside reasonable ranges are discarded, the last valid value is kept. Catches disturbances on the bus and wrongly configured data types. |
| Gust from deviation | If the wind deviates from the average by more than this value, an additional entry is created in the statistics. |
| Test mode | Forces the wind and rain alarms for the configured duration. This makes it possible to check during commissioning whether the blinds move to the safe position correctly without having to wait for a storm. After the time has elapsed the alarms are cleared automatically. |
