Cycle Time
The conversion of the analog output channels for the module takes place with a
processing time and sequentially with a conversion time for channels 0 and 1.
The cycle time, that is, the time until an analog output value is converted again, is
the sum of the conversion times of all the activated analog output channels and of
the processing time of the analog output module.
Figure D-6 provides you with an overview of what makes up the cycle time for an
analog output module.

Settling Time
The settling time (t
value until the specified value is obtained at the analog output – depends on the
load. A distinction must be drawn between resistive, capacitive, and inductive
loads.
