FB_SoEReadCommandState_ByDriveRef

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

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_SoEReadCommandState_ByDriveRef refers, e.g. "P_0_IDN + 160" for P-0-0160
bExecute	BOOL	The command is executed with a rising edge at the Execute input.
tTimeout	TIME	Maximum time (10 s) allowed for the execution of the function block.

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 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 state.
iAdsErrId	UINT	Returns the ADS error code of the last executed command when the bError output is set.
iSercosErrId	UINT	Returns the Sercos error of the last executed command in the event of a set bError output.
