System Availability: Maximize Your Uptime
For process automation, system availability indicates the system's ability to tolerate certain failures and thus maintain continuity in operations. Our solution encompasses this with a fail-safe, fault tolerant architecture capable of emergency shutdowns if needed. Rockwell Automation delivers high availability systems to maintain continuity in operations. Our system allows repairs, replacements, online changes and additions, while continuing with your operation.
Reliability
ControlLogix, which is a core element of the Rockwell Automation process system has been certified by TÜV as a SIL 2 rated system.
- Mean-Time-Between-Failures (MTBF) is well over 100 years
- Availability is 99.9%
Maintainability
Our system offers maintainability advantages such as:
- Diagnostics and reporting of faults
- Ease of replacement or repair while still under power
- Ability to add or make system changes online. For many process applications, the need for redundancy is minimized when the system is modular and repairs are easier to implement.
Platform Redundancy
The system provides for redundancy at all levels, including: power supplies with UPS, processors, network connectivity, HMI, servers and databases, I/O, sensors and actuators. The system has been designed to allow automatic synchronization and fault detection, bumpless and transparent switchover after failure, and failed component replacement without interrupting operation.
