Description
The function block ItpGetBottleNeckLookAheadEx determines the maximum size of the look-ahead for the bottleneck detection (contour collision monitoring).
A more detailed description can be found in the Interpreter documentation.
The function block has the following inputs:
Input | Data type | Description |
---|---|---|
bExecute | BOOL | The command is triggered by a rising edge at this input. |
tTimeOut | TIME | ADS Timeout-Delay |
Input & output | Data type | Description |
---|---|---|
sNciToPlc | NciChannelToPlc | The structure of the cyclic channel interface from the NCI to the PLC. This structure is only accessed for reading. |
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'. If the function block has a timeout error, 'Error' is TRUE and 'nErrId' is 1861 (hexadecimal 0x745). 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). |
nLookAhead | UDINT | Value of the look-ahead for bottleneck detection |
