II. Core Functions

1. 1:1 Primary-Backup Redundancy, Seamless Switching within Nanosecond Level

Support a dual-module 1:1 primary-backup redundancy architecture. The primary module performs real-time control, while the backup module provides full data mirroring for hot backup with synchronization accuracy reaching nanosecond level. In the event of a hardware failure, power fluctuation, communication interruption, or program anomaly in the primary module, the backup module can complete a seamless switch within **<200μs**, without data loss, control interruption, or process disturbance. This completely eliminates the risk of a single point of failure in the control layer and meets the requirements of critical safety circuits such as safety interlocks and emergency shutdowns.

2. Flagship-level Multi-Core Computing, Efficient and Precise Complex Control

Equipped with an industrial-grade quad-core processor (1.5GHz frequency), featuring 2Gb Flash storage and 512Mb high-speed RAM. The computing performance has increased by over 50% compared to the previous generation. It can efficiently execute multi-loop PID regulation, cascade control, feedforward control, complex logic interlocks, advanced process control (APC) algorithms, and massive data processing. It supports multi-task parallel processing, synchronous response to I/O interactions, instruction output, fault diagnosis, redundant synchronization, and upper computer communication. The minimum control cycle can reach 5ms, with extremely low response delay, and is suitable for high-dynamic, high-precision, and high-complexity process control scenarios.

3. Fully Compatible I/O Management, Stable and Reliable High-Speed Bus

VI. Installation and maintenance

1. Installation

Select standard free slots of Ovation cabinets, reserve upper and lower ventilation space (≥8cm), keep away from strong interference equipment such as large power frequency converters, motors, transformers. Wear anti-static wristbands, push the module steadily to ensure reliable contact of the backplane bus, lock the panel screws. When redundant configuration is required, install two modules of the same specification in adjacent slots to facilitate wiring and maintenance, it is recommended to reserve redundant space to ensure heat dissipation and maintenance convenience.

2. Wiring

Connect the module and controller, I/O card with Ovation dedicated shielded communication cables, distinguish the positive and negative poles of the signal, tighten the terminals moderately to avoid loosening and overheating. Shielding layer is reliably grounded at one end, and is separately laid out from power cables, strong current cables, and switch quantity cables (with a spacing of ≥ 50 cm) to reduce electromagnetic interference. After wiring is completed, carefully check the lines to ensure there are no short circuits, incorrect connections, or polarity reversals. After testing the communication connectivity is normal, the system can be put into operation.

3. Daily Maintenance

Regularly (weekly) inspect the status of indicator lights, module appearance, and connection terminals, check for overheating, loosening, corrosion, and dust accumulation; daily check the processor load, module temperature, communication status, redundancy synchronization situation, and fault records through system diagnostic logs; regularly (monthly) use a dry soft cloth or low-pressure clean air to clean surface dust; shorten the cleaning cycle in high dust / high humidity / salt fog environments (every two weeks), and prohibit wiping with corrosive liquids; check the tightness of connection terminals every quarter to avoid loosening; conduct a once-yearly firmware upgrade and hardware health check to ensure the optimal operation of the module.

4. Fault Handling

Communication abnormality: Check indicator lights, connection terminals, bus cables, and redundant links, identify surrounding interference sources, reinsert the module or replace the communication cables, and if necessary, check the status of the bus terminal;

Redundancy out of synchronization: Check module parameter configuration, synchronous cable connection, firmware version consistency, and hardware health status, re-synchronize or upgrade the firmware to ensure that the parameters of the two modules are completely consistent;

Operation failure (red light alarm): Locate the fault by combining system alarm codes (such as overheating, overcurrent, hardware damage, firmware anomaly), perform hot swapping replacement, and after the new module is installed, the system automatically identifies the synchronization program and data, tests normal, and then puts it into operation. The faulty module should be stored in an anti-static sealed container, returned to the factory for repair or testing.
