Input DescriptionΒΆ
Function Block PUMP_RETAIN_DATA
Note
The inputs marked with a triangle 
are of the class VAR_IN_OUT (input and output variable). These inputs must be connected to a variable.
EN (enable)
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
In order to enable the function block processing, input EN has to be continuously set to TRUE. The function block is not processed if input EN = FALSE. While input is set to TRUE, the inputs are continuously checked for validity and plausibility. If this is not the case, processing is aborted and an error is displayed.
STATION_DATA (station data structure)
Data type: PUMP_STATION_TYPE
This structure contains pumping station data. All the Functions Blocks receive some data, process it and write it back to the structure.
