To perform analog input measurements, install a supported analog input C Series module into any slot on the cRIO controller and set the programming mode to Real-Time (NI-DAQmx) mode. The measurement specifications, such as number of channels, channel configuration, sample rate, and gain, are determined by the type of C Series module used. For more information and wiring diagrams, refer to the documentation included with your C Series modules.
The cRIO controller has eight input timing engines, which means that up to eight hardware-timed analog input tasks can be running at a time on the controller. An analog input task can include channels from multiple analog input modules. However, channels from a single module cannot be used in multiple tasks.
Multiple timing engines allow the cRIO controller to run up to eight analog input tasks simultaneously, each using independent timing and triggering configurations. The eight timing engines are it0, it1,…it7.
