IfthelibrarycontainstwoRIMsorF‐QIPs,itcanbeconfiguredtousethe
BlueScaleControllerfailoverfeature.Thisfeatureconfiguresthetwo
controllersasafailoverpairtoprovidearedundantcontrolpathtothe
robotics(seeControllerFailoveronpage77foradditionalinformation).
Ifdesired,youcanconfiguremultipleRIMsandF‐QIPsasexportersforthe

cannotbeusedatthesametime.
