FB_SoEExecuteCommand_ByDriveRef

FB_SoEExecuteCommand_ByDriveRef 1:

With the FB_SoEExecuteCommand_ByDriveRef function block a command can be executed.

FB_SoEExecuteCommand_ByDriveRef 2: Inputs

VAR_INPUT
    stDriveRef : ST_DriveRef; 
    nIdn       : WORD; 
    bExecute   : BOOL; 
    tTimeout   : TIME := DEFAULT_ADS_TIMEOUT;END_VAR

Name

Type

Description

stDriveRef

ST_DriveRef

Reference to the drive. The reference to the drive can be linked directly to the PLC in the System Manager. To do this, an instance of the structure ST_PlcDriveRef must be allocated and the NetID must be converted from the byte array into a string. (Type: ST_DriveRef)

nIdn

WORD

Parameter number to which FB_SoEExecuteCommand_ByDriveRef refers, e.g. "P_0_IDN + 160" for P-0-0160

bExecute

BOOL

The function block is enabled via a positive edge at this input.

tTimeout

TIME

Maximum time (10 s) allowed for the execution of the function block.

FB_SoEExecuteCommand_ByDriveRef 3: Outputs

VAR_OUTPUT
    bBusy        : BOOL;
    bError       : BOOL;
    iAdsErrId    : UINT;
    iSercosErrId : UINT;
END_VAR

Name

Type

Description

bBusy

BOOL

This output is set when the function block is activated, and remains set until a feedback is received.

bError

BOOL

This output is set after the bBusy output has been reset when an error occurs in the transmission of the command.

iAdsErrId

UINT

In the case of a set bError output returns the ADS error code of the last executed command.

iSercosErrId

UINT

In the case of a set bError output returns the Sercos error of the last executed command.
