Structure Data Type Definitions - OpIntPump
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 stVsdCmd structure data type is used to control and switch the states of the VSDs.

Element of stVsdCmd |
Data Type |
Description |
|---|---|---|
|
siNb |
SINT |
Defines the number of VSDs that are available in the system. Range: 1...8 |
|
xAutoMode |
BOOL |
automatic mode When TRUE, the VSD is running in automatic mode without user intervention. |
|
xManMode |
BOOL |
manual mode When TRUE, the VSD is running in manual mode, that means it is controlled by operator inputs. |
|
xMainMode |
BOOL |
maintenance mode When TRUE, the VSD is running in maintenance mode and is not available for the application. |
The stPumpCmd structure data type is used to control and switch the states of the pumps. It is available if the pumping application is running in manual mode (stOpMode.xMan = TRUE).
|
Element of stPumpCmd |
Data Type |
Description |
|---|---|---|
|
siNb |
SINT |
Indicates the number of the pump on which the commands will be executed. Range: 1...8 |
|
esiCmdType |
SINT / Enumeration |
1 = esiCmdType.FixSpeed (Fixed Speed) 2 = esiCmdType.VariSpeed (Variable Speed) |
|
xAutoMode |
BOOL |
When TRUE, the pump is switched to automatic mode. |
|
xManMode |
BOOL |
When TRUE, the pump is switched to manual mode. |
|
xMainMode |
BOOL |
When TRUE, the pump is switched to maintenance mode. |
|
xStrt |
BOOL |
When TRUE, the pump is switched into run state. |
|
xStop |
BOOL |
When TRUE, the pump is switched into stop state. |
|
xByps |
BOOL |
Used if fixed link operational mode is selected. When TRUE, the bypass contactor of the corresponding pump is selected (direct online mode). |
|
xVsd |
BOOL |
Used if fixed link operational mode is selected. When TRUE, the contactor of the corresponding pump to link the VSD is selected. |
|
rManSp |
– |
Manual pressure setpoint |

The OpIntPump function block uses the stPlantCmd structure data type as an input/output variable. The structure is used to control and switch the states of the machine application. This variable is used if there is a local and a remote HMI configured for controlling the pumping application.
The remote HMI control allows you to remotely monitor the application, to perform various maintenance activities, including modifications to data and configuration parameters, and to change the state of the application and associated hardware. Strict care must be taken to be sure that the immediate physical environment of the machine is in a state that will not present safety risks to people or property before exercising control remotely.
NOTE: The documentation of the programming, in particular the parameterization of the HMI, is not part of this document.

|
UNINTENDED EQUIPMENT OPERATION |
|
oConfigure and install the mechanism that enables the remote HMI local to the machine, so that local control over the machine can be maintained regardless of the remote commands sent to the application. oHave a complete understanding of the application and the machine before attempting to control the application remotely. oTake the precautions necessary to assure that you are operating remotely on the intended machine by having clear, identifying documentation within the application and its remote connection. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |

Element of stPlantCmd |
Data Type |
Description |
|---|---|---|
|
xRem |
BOOL |
Command: switch to remote mode When TRUE, the OpIntPump function block switches the operating mode stOpMode.xRem to TRUE. |
|
xLoc |
BOOL |
Command: switch to local mode When TRUE, the OpIntPump function block switches the operating mode stOpMode.xAuto to TRUE. |
|
xAuto |
BOOL |
Command: switch to automatic mode When TRUE, the OpIntPump function block switches the operating mode stOpMode.xLoc to TRUE. |
|
xMan |
BOOL |
Command: switch to manual mode When TRUE, the OpIntPump function block switches the operating mode stOpMode.xMan to TRUE. |
See the related output variable stPlant.
The OpIntPump function block uses the stVsdFbck structure data type as an output variable. The stVsdFbck structure data type contains status bits designed to represent the status and mode of related VSDs on the HMI (for example, by using different colors to represent different states or modes).

siSta |
SINT |
Indicates the status of a specific VSD. Range: Bit 0 = stop Bit 1 = run Bit 2 = alert detected Bit 3 = alarm detected Bit 4 = maintenance |
|
siMode |
SINT |
Indicates the mode of a specific VSD. Range: Bit 0 = manual mode Bit 1 = automatic mode Bit 2 = maintenance mode |
The stPumpFbck structure data type contains status bits designed to represent the status and mode of related pumps on the HMI (for example, by using different colors to represent different states or modes).
