Input |
Data type |
Description |
|---|---|---|
|
bExecute |
BOOL |
The command is triggered by a rising edge at this input. |
|
nChnId |
UDINT |
Channel ID |
|
nDNo |
UDINT |
D-word for which the tool parameters are to be read. nDoNo can assume values between 1 and 50 (the library TcNci.lib from version 5.4.16 supports 255 tool parameters). |

tTimeOut |
TIME |
ADS Timeout-Delay |

Input & output |
Data type |
Description |
|---|---|---|
|
sToolDesc |
ToolDesc |
The structure that contains the new tool parameters. This structure is only accessed for reading. The meaning of the parameters depends on the tool type, and can be found in the tool data. |
|
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). |
