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). |

Input & output |
Data type |
Description |
|---|---|---|
|
sToolDesc |
ToolDesc |
A structure into which the tool parameters of nDNo are written. 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). |
