Structure Data Type Definitions - CompSp
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 stCompInit structure data type contains the initialization data for the CompSp function block.

Data Type |
Description |
|---|---|---|
|
rTn |
REAL |
Defines the stage time (Tn, in milliseconds) for the reference ramp to reach the increased pressure setpoint (i_rSp + iq_stCompInit.rCorrPump(n)). Range: rTn > 0.0 ms Time required (Tn, in milliseconds) to increase the correction value by 1 unit. |
|
rCorrPump1 |
REAL |
Correction value that is added to the pressure setpoint (i_rSp) if the stage value requests 1 pump. |
|
rCorrPump2 |
REAL |
Correction value that is added to the pressure setpoint (i_rSp) if the stage value requests 2 pumps. |
|
rCorrPump3 |
REAL |
Correction value that is added to the pressure setpoint (i_rSp) if the stage value requests 3 pumps. |
|
rCorrPump4 |
REAL |
Correction value that is added to the pressure setpoint (i_rSp) if the stage value requests 4 pumps. |
|
rCorrPump5 |
REAL |
Correction value that is added to the pressure setpoint (i_rSp) if the stage value requests 5 pumps. |
|
rCorrPump6 |
REAL |
Correction value that is added to the pressure setpoint (i_rSp) if the stage value requests 6 pumps. |
|
rCorrPump7 |
REAL |
Correction value that is added to the pressure setpoint (i_rSp) if the stage value requests 7 pumps. |
|
rCorrPump8 |
REAL |
Correction value that is added to the pressure setpoint (i_rSp) if the stage value requests 8 pumps. |
