To generate analog output, install an analog output C Series module in any slot on the cRIO controller. The generation specifications, such as the number of channels, channel configuration, update rate, and output range, are determined by the type of C Series module used. For more information, refer to the documentation included with your C Series module(s).
The cRIO controller has eight output timing engines, which means that up to eight hardware-timed analog output tasks can be running at a time on the controller. On a single analog output C Series module, you can assign any number of channels to either a hardware-timed task or a software-timed (single-point) task. However, you cannot assign some channels to a hardware-timed task and other channels (on the same module) to a software-timed task.
Multiple timing engines allow the cRIO controller to run up to eight analog output tasks simultaneously, each using independent timing and triggering configurations. The eight timing engines are ot0, ot1,… ot7.
