Core Features
High-Performance Processing Capability
The PM866K01 uses a dual-core ARM Cortex-A9 processor with a clock speed of 800MHz, supporting multi-task parallel processing with a task cycle as low as 1ms. 2GB RAM ensures the ability to handle complex control algorithms and logic, supporting real-time processing of 1000+ I/O points.
Redundancy and Fault Tolerance Design
This module supports dual-controller redundancy configuration with a failover time of <10ms, ensuring zero system downtime. Built-in battery-backed RAM ensures no program loss during power outages and supports hot-swapping (I/O modules).
Multi-Protocol Communication Support
Integrates multiple industrial communication protocols, including Modbus TCP, OPC UA, and PROFIBUS DP, enabling seamless connection to third-party devices such as Siemens and Schneider Electric. Dual Gigabit Ethernet ports support PRP (Parallel Redundancy Protocol) and HSR (High Availability Seamless Ring Network).
Safety Features
Built-in fault diagnosis and emergency stop mechanisms, supporting SIL 2 safety level certification to ensure personnel and equipment safety. Full EMC certification is available, complying with IEC 61000-6-2 standards.
Application Areas
Manufacturing
In automotive manufacturing production lines, the PM866K01 is used in the welding robot control system, achieving welding accuracy down to 0.1mm, reducing the failure rate to 0.05%, and lowering annual maintenance costs by 2 million yuan.
Petrochemicals
Application of this module in catalytic cracking units enables 24-hour continuous operation through redundant design, with temperature control accuracy of ±1℃, pressure fluctuation range of ±0.5bar, and product qualification rate increased to 99.9%.
Power Energy
Integrating the PM866K01 into the SCADA system of wind farms, data from over 100 wind turbines is collected via the Modbus TCP protocol, enabling remote monitoring and fault early warning, and increasing annual power generation by 5%.
Water Treatment
Application of this module in the aeration system of wastewater treatment plants, through PID algorithm control of dissolved oxygen concentration, reduces energy consumption by 30%, sludge production by 15%, and saves 1.5 million yuan in annual operating costs.
Technical Advantages
Compatibility
The PM866K01 can directly replace the PM864 or PM865 controller in older systems. The hardware installation dimensions are the same, and only minor software upgrades are needed for operation; no complete overhaul is required.
Easy Programming and Maintenance
Utilizing Control Builder M programming software, project download, online monitoring, and fault diagnosis are all seamlessly integrated. A built-in real-time clock and battery backup ensure data integrity even after power failure, facilitating troubleshooting.
Industrial-Grade Reliability
Equipped with industrial-grade components and design standards, it can operate stably in high-temperature environments and areas with strong electromagnetic interference. With an IP20 protection rating, it is suitable for harsh industrial environments.
Installation and Maintenance
Installation Requirements
The module is mounted on a DIN rail using a standard controller rack (such as CI854). Power is supplied from the PS module via the backplane at 24VDC, ensuring stable operating voltage.
