FB_SoEReadCommandState_ByDriveRef

With the FB_SoEReadCommandState_ByDriveRef function block the execution of the command can be checked.

Inputs

VAR_INPUT
    stDriveRef : ST_DriveRef; 
    Idn        : 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_SoEReadCommandState_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.

Outputs

VAR_OUTPUT
    bBusy        : BOOL;
    bError       : BOOL;
    eCmdState    : E_SoE_CmdState;
    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.
eCmdState	eSoE_CmdState	Returns the command status.
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.
