Issue Details

I am developing an application that will be distributed to a remote location and I want to monitor hardware and system resources for predictive maintenance.

What self-diagnostics options are available in CompactRIo and sbRIO?
What hardware and system resources can I monitor on CompactRIO or sbRIO and how do I access them?

Solution

There is no existing hardware diagnostic utility for Real-Time targets like CompactRIO or sbRIO. You can however measure several system and hardware resources:

CPU and Memory: refer to Monitoring Available Memory on a LabVIEW Real-Time Controller, RT Get CPU Loads VI and the Resource Monitor.vi Shipping Example located <LabVIEW>\examples\nisyscfg to learn the different ways to implement CPU and Memory monitoring.
Temperature: refer to Reading the Temperature of a CompactRIO Chassis, Ethernet RIO Chassis, MXIe-RIO Chassis, or Single-Board RIO Device (FPGA Interface) and How Do I Read the Onboard Temperature Sensors on My sbRIO-9651 System on Module?

Additional Information

In the case of sbRIO devices, an alternative for hardware checking would be implementing it as a feature of the daughter-board, disconnecting the IO from the external circuit and performing connections between inputs and outputs to perform a loopback test. For example, comparing a pattern output with a subsequent input would help identifying damaged IO channels.
