sNetId: A string containing the AMS network identifier of the PC.

nIdn: Parameter number for the command, i.e. "P_0_IDN + 160" for executing a P-0-0160 command

eCmdControl: prepare a command with eSoE_CmdControl_Set := 1, execute a command with eSoE_CmdControl_SetAndEnable := 3 or abort a command with eSoE_CmdControl_Cancel := 0

bExecute: The block is activated by a rising edge at this input.

tTimeout: Maximum time allowed for the execution of the function block.

    Axis : NCTOPLC_AXLESTRUCT;(* reference to NC axis *)
END_VAR

Axis: Axis structure.

VAR_OUTPUT

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

bBusy: This output is set when the function block is activated, and remains set until an acknowledgement is received.

bError: This output is set up after the bBusy output has been reset if there has been an error in transmission of the command.

iAdsErrId: Supplies the ADS error code associated with the most recently executed command if the bError output is set.

iSercosErrId: Supplies the Sercos error code associated with the most recently executed command if the bError output is set.
