ABB PP865A 3BSE042236R2 is a core processor module of ABB's AC800M series PLC , serving as a critical component in industrial automation control systems. It is designed to provide high-performance logic control, process monitoring, and data processing capabilities for small-to-large industrial applications, suitable for discrete manufacturing, process industries, power energy, rail transit, and other scenarios.
| Parameter/Function | Detailed Description |
|---|
| Processor Architecture | - Based on a 32-bit RISC processor with a main frequency of up to 500 MHz, supporting a multi-task real-time operating system (VRTX).
- Equipped with a Floating-Point Unit (FPU) to enhance the processing efficiency of complex algorithms. |
| Memory Configuration | - Program Storage: 256 MB Flash (erasable, used for storing user programs and system firmware).
- Data Storage: 128 MB RAM (used for runtime data and caching). |
| Communication Interfaces | - Ethernet: 2 × 10/100 Mbps auto-negotiation ports, supporting industrial protocols such as PROFINET, EtherNet/IP, and Modbus TCP.
- Serial Port: 1 × RS-232/RS-485 port, supporting protocols like Modbus RTU and ASCII.
- Backplane Bus: High-speed communication with I/O modules and expansion modules via the AC800M dedicated bus (transmission rate up to 100 Mbps). |
| Real-Time Performance and Reliability | - Supports hot redundancy configuration (requires a redundancy kit), enabling seamless switching between primary and standby controllers to ensure continuous system operation.
- Built-in Watchdog timer and error-checking mechanisms (e.g., CRC checking), with electromagnetic compatibility (EMC) and wide-temperature operation capabilities (-20°C ~ +60°C). |
| Programming and Configuration | - Compatible with ABB's Control Builder M programming software, supporting IEC 61131-3 standard programming languages (Ladder Diagram, Structured Text, etc.).
- Supports online debugging, firmware upgrades, and version management. |
| Expansion Capability | - Each controller can connect to up to 128 I/O modules (via local or remote expansion racks).
- Supports functional module expansion (e.g., motion control modules, safety modules, communication gateways). |
