Limitations with "FB_SpeedLimit_WarningFields"

The task of the FB_SpeedLimit_WarningFields function block is to switch the vehicle to the next lower speed range that was parameterized during the creation of the scanning fields if the warning field is violated. For this purpose, the function block specifies speed and acceleration limits for the master block.

The speed limits can be parameterized for manual and automatic mode. Use xManualMode and xAutomaticMode to switch the limits to the outputs.

The function block can respond to a warning field from the safety controller as follows:

1. As soon as xWarningFieldViolated becomes true, the vehicle can no longer accelerate, and the speed limit is continuously reduced to the lrMinimalVelocity value.
2. When the lrMinimalVelocity value is reached, the vehicle continues to travel at this speed until a safety field is violated or the warning field is exited.
3. As soon as the warning field is exited, the vehicle accelerates again after an adjustable delay time.
