Structure Data Type Definitions - DevSwcPumpCtrl
Structure data types serve as the major input and output data carriers between different function blocks, configuration, and parameterization data.
The following section lists the names of structures (data types) that are used in this function block, followed by a table that describes the elements of structure.
NOTE: For the structure data types that are used from this function block and others, refer to the Common Structure Data Type Definitions chapter.
The stSwcInit structure data type contains the initialization data for the DevSwcPumpCtrl function block (refer to the examples).

xFlexStart |
BOOL |
When TRUE, flexible start is used. |
|
xFixLink |
BOOL |
When TRUE, the links between the VSDs and the VS pumps are fixed. |
|
xByPass |
BOOL |
When TRUE, the VS pumps can bypass the VSDs. |
NOTE: The elements of the structure data type are set to the default values (0 or FALSE) assigned by the controller on system startup.
The stSwcErr structure data type is used to indicate the detected alarms or alerts.
|
Element of stSwcErr |
Data Type |
Description |
|---|---|---|
|
stSwcAlrm |
stSwcAlrm |
The structure data type for detected alarms. |
|
stSwcAlrt |
stSwcAlrt |
The structure data type for detected alerts. |
The stSwcAlrm structure data type is used to indicate the detected alarm states.
|
Element of stSwcAlrm |
Data Type |
Description |
|---|---|---|
|
xLinkErr |
BOOL |
When TRUE, it has been detected that the VSD and the VS pump are not in the same state of operation (run or stop). |
|
xStagErr |
BOOL |
When TRUE, it has been detected that the stage value is not valid because it does not comply with the number of pumps. |
|
xParaErr |
BOOL |
When TRUE, an error in the configuration has been detected. |
The stSwcAlrt structure data type is substructure of stSwcErr. It is used to indicate the detected alert states.
|
Element of stSwcAlrt |
Data Type |
Description |
|---|---|---|
|
xNoVsPlusFs |
BOOL |
When TRUE, a configuration error has been detected: The stage value demands a higher number of pumps than the maximum number of pumps (FS pumps and VS pumps) configured for simultaneous use. |
