Brief Description

The OpIntAuxPump function block allows the operator to influence the auxiliary pump via inputs on an HMI terminal.

I/O Variables Description

The table describes the input/output variables of the function block:

Input/Output

Data Type

Description

iq_stAlrmCtrl

stAlrmCtrl

Structure used for alarm handling. Refer to the structure data type description.

iq_stOpMode

stOpMode

Determines the operating modes.

If this structure data type is set to xMan, the function block accepts and executes commands entered by the operator. Automatic commands are rejected.

If this structure data type is set to xAuto, the function block verifies whether an error has been detected. If not, it forwards the commands consecutively to the output pins.

If an error has been detected (iq_stOpMode.xAlrm), the outputs of this function block are set to their defined fallback (default) states.

Refer to the structure data type description.

iq_stMode_Aux

stMode

Structure to control and switch the operating mode of the auxiliary pump.

Refer to the structure data type description.

iq_stPumpCmd_Aux_Hmi

stPumpCmd

Structure used to control and switch the states of the auxiliary pump.

Refer to the structure data type description.

The table describes the input variables to the function block:

Input

Data Type

Description

i_xRele

BOOL

Activates (TRUE) or stops (FALSE) the execution of the function block.

i_stSta_AuxPumpEx

stSta

Structure that contains the status of the auxiliary pump.

Refer to the structure data type description.

i_xFbckErr

BOOL

This pin is linked to the feedback error, detected by the AuxPumpCtrl function block.

i_stAuxPumpCom

stAuxPumpCom

The structure contains the command bit for the auxiliary pump inclusive of the state. If the state bit is set to TRUE the command bit is valid.

Refer to the structure data type description.

The table describes the output variables from the function block:

Output

Data Type

Description

q_stPumpFbck_Aux_Hmi

stPumpFbck

The structure stPumpFbck is used to display the status and the modes of the auxiliary pump.

Refer to the structure data type description.

q_stAuxPumpCom_Ex

stAuxPumpCom

The structure contains the command bit for the auxiliary pump inclusive of the state. If the state bit is set to TRUE the command bit is valid.

Refer to the structure data type description.
