3 What it is High Availability High availability is a system implementation that ensures a certain absolute degree of operational continuity during a given time period. (Mission Period) Availability is the readiness for a system to perform when needed. Availability refers to the ability of the user community to access the system, whether to submit new work, update or alter existing work, or collect the results of previous work. In a control system environment, availability also means the control system is performing it s designed function while doing any of the above things. High availability techniques are used to Modify a running system Reduce planned outages 2. Prevent unplanned outages Availability is measurable Represented as a % Commonly known as number of nines High availability is more than Redundancy! 3

4 High Level Availability in a ControlLogix System Availability % Possible Downtime per Year 99% 3.65 days 99.9% 8.76 hours 99.99% 52.6 minutes % 5.26 minutes % 30 seconds Standard ControlLogix Redundant CLX Availability is measurable as a %: A = MTBF / MTBF+MTTR Copyright 2012 Rockwell Automation, Inc.

5 How CLX increases Availability Maintainability Improved Diagnostics: Internal diagnostics to detect failures and LED indicators Diagnostic I/O modules: Wire off, shorts, etc. Hart and other Fieldbus technology with sensor & actuator diagnostics. Alarms and Events Inherent Machine Diagnostics Runtime Modifications: Runtime partial import. Online Edits RIUP of 1756, 1715 and 1794/1797 modules Addition of 1756 and 1715 modules in Run mode ControlLogix Redundancy adds the ability to update firmware at Runtime Ease of Maintainability Results in Minimized Downtime Copyright 2012 Rockwell Automation, Inc.

8 8 ControlLogix Redundancy Dual Chassis Design Full Redundancy Both Chassis match Transparent Primary/Secondary Chassis IP Address Swap ControlNet Node Swap Easy to use No special code Automatic Crossload Treat as one chassis Uses Standard 1756 hardware Up To: 2 Controllers 7 Communications Modules

9 9 CLX Redundancy Overview Operation Basics Application from Primary is automatically loaded into the Secondary processor Data changes are sent to secondary at the end of each program. The Secondary controller is Synchronized with the Primary via Sync Points at each crossload point. System is Floating Master type. Each chassis is capable of being Primary Primary Chassis 1756-RM2 Secondary Chassis

11 11 CLX Redundancy Considerations What can t I do with a CLX Redundancy System Put the following modules in a Redundancy Chassis I/O DH/RIO DNB Most Third party modules Motion Control Sercos or CIP Motion Inhibit a Task Event Task Unicast Data Redundancy System can be Producer to another controller as Unicast. Firmware Supervisor Anything that makes use of a storage card will be stored on two controllers in the event of a switchover.

12 12 CLX Redundancy Conclusion Easy to use Single program to maintain Data is automatically Crossloaded Single Checkbox to enable Redundancy Uses standard CLX hardware Transparent IP address and MAC address follows Primary Most devices on network are unaware of a switchover Chassis switchover in 20ms range on average Primary Chassis Secondary Chassis 1756-RM2

24 High Availability Network Architecture Provides resiliency at the device level through dual port devices. Ideal applications include: Where there are Low cost and ease of use resiliency requirements Migration from field bus networks CIP Sync applications Where users do not want to use central switches Can recover in as fast as 3 ms for a 50 node ring worst case Lower cost to implement than other resilient network types Device-Level Ring Single fault tolerant network provides resiliency Device level ring requires no additional hardware to implement Copyright 2012 Rockwell Automation, Inc.
