The Limit Checker (LC) is a core Flight System (cFS) application that is a plug in to the Core Flight Executive (cFE) component of the cFS.
The LC application monitors telemetry data points in a cFS system and compares the values against predefined threshold limits. When a threshold condition is encountered, an event message is issued and a Relative Time Sequence (RTS) command script may be initiated to respond/react to the threshold violation.
The LC application is written in C and depends on the cFS Operating System Abstraction Layer (OSAL) and cFE components. There is additional LC application specific configuration information contained in the application user's guide.
User's guide information can be generated using Doxygen (from top mission directory):
