FB_AX2000_Parameter

The function block FB_AX2000_Parameter is used to write/read the data for parameterizing the drive.

	Please note that the "STOP" input of the AX2000AXACT function block must remain TRUE while writing a parameter to change the operation mode.

Inputs

VAR_INPUT
    iSlaveAddress   : BYTE := 0;(* Station Address of the Slave *)
    iPnu            : WORD := 16#03A2;(* Parameter-Number *)
    nAxis           : BYTE := 1;(* Number of Axis *)
    iLength         : BYTE := 4;(* Length of the parameter (2 or 4) *)
    iSubIndex       : BYTE;
    iParameterValue : DWORD := 2;(* Parameter value *)
    iFC310xDeviceId : WORD := 1;(* Device-ID of the FCxxxx *)
    bStartRead      : BOOL;(* StartFlag to start the PKW-Read *)
    bStartWrite     : BOOL;(* StartFlag to start the PKW-Write *)
    tTimeOut        : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

Name	Type	Description
iSlaveAddress	BYTE	Station address
iPnu	WORD	Selection of the parameter to be read or written. List of the available parameter numbers.
nAxis	BYTE	Axis ID
iLength	BYTE	Length of the parameter (2 or 4)
iSubIndex	BYTE
iParameterValue	DWORD	Value of the parameter to be read or written.
iFC310xDeviceId	WORD	Device-ID
bStartRead	BOOL	A positive edge at this Boolean input sends a start command to the axis to read the parameter selected with 'Pnu'.
bStartWrite	BOOL	A positive edge at this Boolean input sends a start command to the axis to write the parameter selected with 'Pnu'. When changing the operation mode, the write command is only effective with Stop=TRUE on the FB_AX2000_AXACT function block.
tTimeOut	BOOL	Maximum time allowed for the execution of the command.

Outputs

VAR_OUTPUT
    bBusy      :BOOL;
    iErrorId   :DWORD;
    iReadValue :DINT;
END_VAR

Name	Type	Description
bBusy	BOOL	This output remains TRUE until the function block has executed a command. While Busy = TRUE, no new command will be accepted at the inputs. Note that it is not the execution of the service that is monitored in terms of time, but only its acceptance.
iErrorId	DWORD	Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs.
iReadValue	DINT	Parameter value as a response to the "StartRead" command.

Requirements
