CSLS ControlStatus diagnostic parameter

Name Context Path Description

ControlStatus

CSLS

CSLS_NAME/CONTROL_STATUS,

CSLS_NAME/REDU/STBY/CONTROL_STATUS

Status of the Control Subsystem

Conditions Meaning Mapping Impacts Integrity
Control Data Mismatch Between Cores The control subsystems have determined a mismatch in dynamic data other than outputs and secure parameter values. Advise Y
Modules Not Executing At Configured Scan Rate The logic solver has set the actual scan rate longer than the configured scan rate based on the estimate of execution time at download. Maintenance Y
Error on Non-Volatile Memory Restore The control subsystem was not able to restore saved parameter records after a powerup or restart and has initialized non-volatile memory. The CSLS is in an unconfigured state. The error is cleared on the next download or reset. Maintenance Y
Less Than 5 Percent of Parameter Records Available Non-volatile memory availability to store parameter change records is low. Advise Y
Cyclic Redundancy Check Error on Non-Volatile Memory A CRC error occurred when writing a parameter record or during periodic check Maintenance Y
All Non-Volatile Memory Parameters Records Exhausted@ No more non-volatile memory is available for parameter change records Advise Y
Proof Test Reminder is Active The logic solver proof test timer is within the reminder period of the required interval. Advise N
Proof Test is Overdue The logic solver proof test timer has exceeded the required interval. Advise N
