Product Performance

Adopting single-core industrial processor and real-time operating system (RTOS), the conventional control loop cycle is ≤5ms, speed control accuracy is ±0.1% rated speed, and pressure/flow regulation accuracy is ±0.5% full scale, which can meet the control needs of small and medium-sized auxiliary equipment. Although there is no hardware redundancy, it has built-in software-level fault self-recovery function, and a single transient fault can restart the control loop within 100ms, reducing unplanned downtime.

The data interaction delay with Mark VIe I/O modules is ≤20ms, and the Ethernet port supports PROFINET protocol, which can be directly connected to the factory-level monitoring network. Real-time equipment status monitoring and remote parameter modification can be realized through Proficy PlantPAx software. The fault diagnosis system can monitor the status of key components such as processor, memory, communication interface and power supply, with diagnostic coverage ≥95%, and fault information is uploaded to the monitoring platform in real time via Ethernet.

Supports online firmware upgrade and parameter configuration, and the upgrade process does not require interrupting the control loop, adapting to 24/7 continuous production scenarios. Industrial-grade wide-temperature design and anti-electromagnetic interference capability ensure stable operation in complex environments such as turbine rooms and pump stations, with Mean Time Between Failures (MTBF) ≥600,000 hours (MIL-HDBK-217F, 25℃ environment).
