ItpPpgAppendGeoLine

ItpPpgAppendGeoLine 1:

The function block ItpPpgAppendGeoLine adds a linear motion to the parts program. In addition to the actual target position, the path velocity and the line number are transferred.

Before the actual call, call ItpPpgCreateMain or ItpPpgCreateSubroutine.

END_VAR

Name

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

fTargetXPos

LREAL

Target position of the X axis

fTargetYPos

LREAL

Target position of the Y axis

fTargetZPos

LREAL

Target position of the Z axis

fPathVelo

LREAL

Path velocity

nBlockNo

UDINT

Line number in the parts program

tTimeOut

TIME

ItpPpgAppendGeoLine 3: Outputs

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

Name

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).
