Oversampling

During each bus cycle a conventional analog output terminal processes a set of process data ("sample") per output channel and outputs an analog output value per fieldbus cycle.
During each fieldbus cycle the EL47xx can handle not just one output value, but a packet of several 16-bit output values per channel. The EL47xx outputs this set of values at equidistant intervals. The time ratio between the fieldbus cycle (e.g. 1 ms) and the output period (e.g. 50 µs) is referred to as oversampling factor (here: 1 ms / 50 µs = 20). The oversampling factor and therefore the EL47xx process data can be configured via corresponding dialogs.
