ItpPpgAppendGeoCircleByRadius

ItpPpgAppendGeoCircleByRadius 1:

The function block ItpPpgAppendGeoCircleByRadius adds a circular motion to the parts program. The circle is parameterized by the radius.

Before it is called, ItpPpgCreateMain or ItpPpgCreateSubroutine should be called.

The function block ItpPpgAppendGeoCircleByRadius has the following inputs:

Interface

VAR_INPUT
    bExecute       : BOOL;
    sPathName      : STRING;
    bClockWise     : BOOL;
    fTargetXPos    : LREAL;
    fTargetYPos    : LREAL;
    fTargetZPos    : LREAL;
    fRadius        : LREAL;
    fPathVelo      : LREAL;
    nBlockNo       : UDINT;
    tTimeOut       : TIME;
END_VAR

VAR_OUTPUT
    bBusy          : BOOL;
    bErr           : BOOL;
    nErrId         : UDINT;
END_VAR

Input	Data type	Description
bExecute	BOOL	The command is triggered by a rising edge at this input.
sPathName	STRING	Name of the parts program including path name
bClockwise	BOOL	If TRUE, the movement along the circle is clockwise, otherwise counter-clockwise
fTargetXPos	LREAL	Target position of the X axis
fTargetYPos	LREAL	Target position of the Y axis
fTargetZPos	LREAL	Target position of the Z axis
fRadius	LREAL	Circle radius
fPathVelo	LREAL	Path velocity
nBlockNo	UDINT	Line number in the parts program
tTimeOut	TIME	ADS Timeout-Delay

Output	Data type	Description
bBusy	BOOL	This output remains TRUE until the function block has executed a command, but at the longest for the duration supplied to the 'Timeout' input. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.
bErr	BOOL	This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in ‘nErrId’. Is reset to FALSE by the execution of a command at the inputs.
nErrId	UDINT	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. The error numbers in ErrId can be looked up in the ADS error documentation or in the NC error documentation (error codes above 0x4000).
