    NetId   : T_AmsNetId := '';
    Execute : BOOL;
    Timeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

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

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

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

VAR_IN_OUT

VAR_IN_OUT
    Axis : AXIS_REF; (* Axis reference *)
END_VAR

Axis: Axis structure (see TcMC2.lib).

VAR_OUTPUT

VAR_OUTPUT
    Busy          : BOOL;
    Error         : BOOL;
    AdsErrId      : UINT;
    SercosErrId   : UINT;
    DcBusCurrent  : REAL;
    Attribute     : DWORD;
END_VAR

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

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

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

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

Attribute: Supplies the Sercos parameter attribute.

DcBusCurrent: Supplies the DC-Bus-Current (i.e. 2.040 means 2.040A).
