Detailed Description

One of a fixed number of slots for a frame on the wire. Released when destroyed.

SOEM has a fixed number of frame indexes (EC_MAXBUF), shared by every thread that sends a frame. When none is free, ecx_getindex hands out one that is still in use, and two frames then share it. Each holder of a slot sends one frame at a time, so the slots bound how many frames the control plane has on the wire.
