ItpRetraceMoveForward
from library version 6.1.24 and anticipated with TwinCAT version 2.10 Build 1308
The function block ItpRetraceMoveForward transfers all entries from the current block (e.g. position) in forward travel direction to the NC kernel. It is called to reverse the direction after ItpRetraceMoveBackward was called.

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). |
