Further information on smoothing
For information showing whether a specific module supports smoothing functions, and
special features to observe, refer to the chapter dealing with the analog input module.
Conversion time of the analog output channels
The conversion time of the analog output channels includes the transfer of digitized output
values from internal memory, and their digital-to-analog conversion.
Cycle time of analog output channels
Analog output channels are converted sequentially, i.e. successively.
The cycle time, i.e. the time expiring until an analog output value is converted again, is
equivalent to the accumulated conversion times of all activated analog output channels.
Refer to the figure
Cycle time of an analog IO channel
.
Tip
You should disable all unused analog channels in STEP 7 in order to reduce cycle times.
