FB_SoEReadCommandState

With the FB_SoEReadCommandState function block the command execution can be checked.

Inputs

VAR_INPUT
    sNetId   : T_AmsNetId := '';
    nIdn     : WORD;
    bExecute : BOOL;
    tTimeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

Name	Type	Description
sNetId	T_AmsNetId	String, which contains the AMS Network ID of the PC (type: T_AmsNetId).
nIdn	WORD	Parameter number to which FB_SoEExecuteCommand 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 allowed for the execution of the function block.

Inputs/outputs

VAR_IN_OUT
    Axis : NCTOPLC_AXIS_REF;(* reference to NC axis *)
END_VAR

Name	Type	Description
Axis	NCTOPLC_AXIS_REF	Axis data structure of the type NCTOPLC_AXIS_REF

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	E_SoE_CmdState	Returns the command state (see below).
iAdsErrId	UINT	Returns the ADS error code of the last executed command when the bError output is set.
iSercosErrId	UINT	In the case of a set bError output returns the Sercos error of the last executed command.
