Sync to SM event Timing
In the this operating mode the process data will be sampled and copied subsequently into the Sync Manager
buffer every time the data has been read out by the master, this means that the sampled data is synchronous
to the read out events of the master. One disadvantage of this mode is that for large cycle times the data
may be relative old for a RT system; however data is synchronized to the masters readout event.
