SMC_QueueSetReservedEntries (FB)¶

FUNCTION_BLOCK SMC_QueueSetReservedEntries

This function block allows to set the number of reserved entries in the queue. If the number of free entries in the queue reaches this threshold, SMC_OutQueue.bFull will return TRUE.

This function block is intended for use with SMC_Interpolator2Dir. It can be used to set the number of elements that can be interpolated in reverse direction.

Note

SMC_QueueSetReservedEntries is intended to be used after the last path processing function block that copies the queue. It will not work as desired when used after SMC_CheckVelocities or SMC_CheckForLimits . (These function blocks don’t copy the queue but modify it in-place.)
