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

aNetId: Provide the AmsNetId of the Profibus Master device (see ADS-Tab of the Profibus Master device in the I/O configuration in the System Manager).

iProfibusSlaveAdr: The profibus slave DP address of the drive. This is one address for a multiple axes drive specified in the TwinCAT System Manager in the hardware configuration.

iDriveID: The drive ID is 1 for the ControllerUnit, 2 for the A drive, 3 for the B drive of double/triple drive. Drive ID is set in the Starter software. 1..16 is possible.

pDpv1ReqData: Pointer to an array of 240 bytes, which contains the DPV1 request telegram. This telegram needs to be created with F_CreateDpv1WriteReqPkg before the executing the DPV1 write.

iDv1ReqDataLen: Maximum length of the DPV1 request data buffer (240 bytes).

pDpv1ResData: Pointer to an array of 240 bytes, which contains the DPV1 response telegram after the DPV1 read. This DPV1 response telegram needs to be split with F_SplitDpv1WriteResPkg after the bBusy sends a falling edge.

iDv1ResDataLen: Maximum length of the DPV1 response data buffer (240 bytes).

tTimeout: States the length of the timeout that may not be exceeded by execution of the ADS command.

    bBusy         : BOOL;
    bError        : BOOL;
    bErrorValues  : BOOL;
    iErrId        : UDINT;
    iErrorClass   : BYTE;
    iErrorCode    : BYTE;
END_VAR

bBusy: When the function block is activated this output is set. It remains set until and acknowledgement is received.

bError: If an ADS error should occur during the transfer of the command, then this output is set once the bBusy output is reset.

bErrorValues: Is TRUE if the DPV1 Read was not successful or partly not successful. The response telegram contains error values.

nErrId: Supplies the ADS error number or function block specific error code when the bError output is set.

nErrClass: Profidrive error class

nErrCode: Profidrive error code

VAR_IN_OUT

VAR_OUTPUT
    iRequestRef : USINT; (* 1..127; 0: reserved *)
END_VAR

iRefRequest: Reference, which is increased automatically with each telegram. The reference is needed to assign the response telegram to the corresponding read/write request telegram.
