This example demonstrates how to programmatically discover, configure and access NI 9211 module in Compact RIO Scan Mode.
This application is an example of programmatically discovering, configuring, and accessing CompactRIO Scan Mode I/O in LabVIEW. The LabVIEW Real-Time Module starting at version 2009 and NI-RIO 3.2 increase the flexibility of CompactRIO Scan Mode, giving you the ability to programmatically discover, configure, and access I/O in a deployed system. Using the new programmatic I/O API, applications can be developed to handle the presence of any combination of supported C Series I/O Modules. For example, a single CompactRIO system could be used as simple temperature data logger when thermocouple input modules are present or as a closed-loop motor controller when PWM output and quadrature encoder input capable digital I/O modules are present, without deploying new settings from a development machine.
This example shows how to use programmatic Scan Mode API to discover, configure and access inputs of a NI 9211 thermocouple module. It can easily be modified to support other modules as well (especially other thermocouple modules).
