AutoIdent
![]() | Exclusive function for hydraulic axes This core function is only available for hydraulic axis types. |

This core function is used to analyze the non-linear transfer characteristic of hydraulic axes. It belongs to the group of statically controlled Corefunctions.
Syntax:
FUNCTION_BLOCK FB_AutoIdent EXTENDS FB_CorefunctionFeedback
Properties
Name | Type | Access | Description |
---|---|---|---|
InitState | BOOL | Get, Set | The core function is not completely and successfully initialized. |
FB_CorefunctionFeedback | |||
AbortedState | BOOL | Get, Set | Signals the abort of a command by another Corefunction. |
BusyState | BOOL | Get, Set | Signals the active execution of a command. |
DoneState | BOOL | Get, Set | Signals the successful execution of a command. |
IdleState | BOOL | Get, Set | The Corefunction is ready for operation and commandable. |
IsCommanded | BOOL | Get | Signals the pending of a command. |
FB_Corefunction | |||
FailedState | BOOL | Get, Set | If IsActivated is TRUE at the same time: Signals the failure of an accepted command. If IsActivated is FALSE at the same time: Signals the rejection of a command. |
HasFeedback | BOOL | Get | The core function has responded to a pending command. |
IsActivated | BOOL | Get | The core function has an accepted command pending. |
IsLocalCmd | BOOL | Get | Signals that the axis is assigned with a command of this core function. |
ReadyState | BOOL | Get, Set | The Corefunction is ready for operation, but is not commandable at this time. Possible reasons are: |
Methods
Name | Description |
---|---|
[ | This method is called cyclically by the axis. |
FB_AutoIdent | |
Activates and terminates the measurement procedure. | |
Sets the parameters for the measurement procedure. |
Interfaces
Type | Description |
---|---|
I_Corefunction | Standard interface on FB_Corefunction. |
I_AutoIdent | Standard interface on FB_AutoIdent |
I_CorefunctionFeedback | Standard interface on FB_CorefunctionFeedback. |
Example:
// This sample requires the Autoident parameters set by the PlcMcManager in 'LinDef'
// Get specific interface I_AxisHydraulicBase from general interface I_AxisBase
IF __QUERYINTERFACE(iAxisBase, iAxisHydraulic) THEN
// abort or done
IF bAbort OR iAxisHydraulic.AutoIdent.DoneState THEN
bAutoIdent := FALSE;
iAxisHydraulic.AutoIdent.DoAutoIdent(FALSE);
// start the command
ELSIF bAutoIdent THEN
hresult := iAxisHydraulic.AutoIdent.DoAutoIdent(TRUE);
END_IF
ELSE
// interface is not set to an instance of FB_AxisHydraulicBase
bIncompatible := TRUE;
END_IF
