FB_SoEExecuteCommand
With the FB_SoEExecuteCommand function block a command can be executed.
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 | Axis data structure of the type NCTOPLC_AXIS_REF |
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 | 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. |
