When the Transfer to queue block runs, it checks the queue capacity to determine whether the queue is at capacity (full). This check for queue capacity compares the current number of contacts in the queue to the Maximum contacts in queue limit, if one is set for the queue. If no limit...

You can specify the capacity of the queue, and the policy when the queue is full. The block supports three different message or queue sorting policies, first-in-first out (FIFO), last-in-first out (LIFO), and priority. The priority queue can be used only when theOverwrite the oldest el...
