1TGE120021R0010 is a high-performance processing unit in ABB’s AC800M series controller, designed for industrial automation control systems. It is based on a modular architecture, integrates CPU, communication module and power supply unit, supports redundant configuration, and is suitable for complex control scenarios in industries such as power, petrochemical, metallurgy, and water treatment.
Processor and memory
Equipped with an industrial-grade PowerPC architecture processor, it supports multi-task parallel processing.
Standard 128MB memory (expandable to 512MB), 32MB Flash storage, and supports external memory card expansion.
Hardware configuration
CPU module: adopts a rail-mounted design, supports multiple models (such as PM851, PM856, PM860, PM861, PM864, PM865), and the processing power, memory capacity and redundancy support vary depending on the model. For example, the PM865 model supports SIL3 safety integrity level and is suitable for scenarios with high safety requirements.
Communication interface:
Built-in 2 Ethernet ports (supports redundant configuration to improve system availability).
2 RS-232C ports for communication with programming tools or third-party devices.
Extended fieldbus interfaces such as Profibus DP, Profinet IO, Modbus TCP, etc.
I/O expansion capability:
Local I/O: connected via Modulebus, supports up to 8 S800 I/O stations.
Remote I/O: through Profibus DP expansion, can manage up to 98 remote stations, with a transmission distance of 500 meters (cable) or 2 kilometers (optical fiber).
Performance parameters
Supports a minimum task cycle of 1ms, SOE (sequence of events) resolution <1ms.
Redundancy switching time <10ms, ensuring high system availability.
Wide operating temperature range (-20℃ to +60℃), adaptable to harsh industrial environments.
Features
Openness and compatibility
Supports multiple communication protocols (such as Profibus, Profinet, Modbus TCP, Ethernet/IP, Foundation Fieldbus, etc.), and can seamlessly integrate third-party devices.
Compatible with ABB traditional protocols (such as AF100, MB300, DDCS), which is convenient for upgrading old systems.
Programming and configuration
Use Compact Control Builder tool to support IEC 61131-3 standards (function block diagram, ladder diagram, structured text, etc.) and ABB’s unique Control Module language.
Provides predefined function block library (such as PID control, fuzzy logic) and supports user-defined function blocks.
Redundancy and safety
Dual Ethernet ports can be configured as redundant mode to avoid single point failure.
High integrity versions (such as PM865) are TÜV SIL3 certified and suitable for safety instrumented systems (SIS).
Scalability and flexibility
Supports up to 12 communication module expansions to adapt to complex network architectures.
Supports local/remote I/O hybrid configuration to meet the needs of applications of different scales.
Application areas
Process industry: continuous process control in energy (power generation, transmission and distribution), chemical, oil and gas, pharmaceutical, cement and other industries.
Discrete manufacturing: scenarios that require high-precision synchronous control, such as automobile production lines, robot control, and packaging machinery.
Infrastructure: municipal engineering such as water treatment, sewage treatment, and pump station control.
Special applications: automation systems in harsh environments such as offshore platforms and mines.
Continuous production process control
Closed-loop control of parameters such as temperature, pressure, flow, and liquid level in the petrochemical and power industries.
Examples: boiler control systems, distillation tower automation.
Logic and sequential control
Applicable to production line control (such as assembly lines and packaging lines) in automobile manufacturing and food and beverage industries.
Infrastructure and safety systems
Traffic signal control, building automation, and energy management systems.
Emergency shutdown system (ESD), fire alarm system.
