Use the Clear Saved Fault Information command when any problems reported by the redundant card pair have been identified and resolved. This command re-enables switchovers if the same problems are detected again. One way to determine if you need to use this command is to look at the card's SwitchAvail parameter. If the value for the SwitchAvail parameter reads "Available - common fault" or "Unavailable - both cards faulty" send the Clear Saved Fault Information command.
For example, suppose a wire becomes loose on an Analog Input termination block. As soon as the active card detects the open loop, the controller records the fault, and the redundant pair switches over. Then, the new active card detects the open loop, and the controller records the fault again. Now, detection of the same open loop will not cause a switchover. In a situation such as this, once you find and secure the loose wire, use the Clear Saved Fault Information command to enable switchover if the condition is detected again.
