ItpConfirmHsk
from library version 4.0
The ItpConfirmHsk function block confirms the currently present M-function.
If the channel override is set to 0 or an E-stop is active, no M-functions are acknowledged during this time. The busy signal of ItpConfirmHsk therefore remains active and must continue to be called.

sNciToPlc |
NciChannelToPlc |
The structure of the cyclic channel interface from the NCI to the PLC. This structure is only accessed for reading. |
|
sPlcToNci |
NciChannelFromPlc |
The structure of the cyclic channel interface from the PLC to the NCI. |

Output |
Data type |
Description |
|---|---|---|
|
bBusy |
BOOL |
This output remains TRUE for as long as the request bit of the M-function is set to FALSE in the channel interface. |
|
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). |
