The function block ItpSetBottleNeckMode specifies the behavior in the event of a contour collision (bottleneck).

There is a more detailed description 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.
nChnId	UDINT	Channel ID
eBottleNeckMode	E_ItpBnMode	Enum for the behavior in the event of a contour collision
tTimeOut	TIME	ADS Timeout-Delay

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).
