所有重要领域均可选配冗余，包括电源、CHU、通讯链路和I/0电路。以此为基础，并结合800x控制和I/0其它大量特色功能，在可能限度内实现工厂高程度的可用性。实现了多种冗余选项，即可实现大的可用性。控制和I/0子系统中所有关键领域均可采用冗余。这些领域包括控制网络、现场总线、内部总线、电源、CPU和I/0。主电路中发生时会平滑切换到备用电路，确保运行无间断。如某个控制器发生，则可通过子系统的通讯总线隔离与切换方案，保持现场总线通讯冗余功能不受损害。而AC 800M HI 控制器提供了更强的可用性。通过”安全模块”实现的高级诊断提供了更高的完整性，并且在那些对业务具有关键意义的控制应用中可更好地利用冗余性。
