Struct FaultDetector 

pub struct FaultDetector {
    pub comm_timeout: Option<Duration>,
}

Fault detection engine.

Call FaultDetector::evaluate periodically (e.g. every 10 s) against the object database. It returns a list of objects whose reliability changed so the caller can update them.

Fields

comm_timeout: Option<Duration>

Timeout after which an object is considered to have a communication failure. Set to None to disable communication-failure detection.

Implementations

impl FaultDetector

pub fn new(comm_timeout: Option<Duration>) -> Self

Create a new fault detector with the given communication timeout.

pub fn evaluate(&self, db: &mut ObjectDatabase) -> Vec<ReliabilityChange>

Evaluate reliability for all objects in the database.

For each analog object (AI, AO, AV) that has MIN_PRES_VALUE and MAX_PRES_VALUE properties, the present value is compared against those limits. If out of range the reliability is set to OVER_RANGE or UNDER_RANGE; otherwise NO_FAULT_DETECTED.

Returns a list of changes that were applied to the database.

Trait Implementations

impl Default for FaultDetector

fn default() -> Self

Returns the “default value” for a type.
