Functional Characteristics
- Triple Modular Redundancy (TMR) Structure: The 9771-210 is based on the TMR architecture, providing unparalleled reliability and fault tolerance. Each channel operates independently and in parallel with the other two, ensuring continuous operation even in the presence of a single-point failure.
- Hardware Voting Mechanism: The system employs a hardware voting mechanism for digital inputs and outputs, and median value selection for analog inputs. This ensures accurate and reliable signal processing.
- Extensive Diagnostics: Comprehensive diagnostic capabilities allow for timely detection of faults in individual circuits, modules, and functional circuits. Fault information is stored within system variables, aiding in troubleshooting and maintenance.
- Hot Swappable Modules: Modules can be replaced online without interrupting the process control, provided hot backup cards are available and operational.
- Graphical Editing: The 9771-210 supports graphical editing, enabling users to configure multiple objects jointly and display related tags on a single display.
- Ease of Use: From a user perspective, the TMR system operates like a single control system, simplifying operation and reducing complexity.
