The AC 800M is a high-performance, modular process controller designed for industrial automation applications, delivering reliable and precise control across diverse process environments. Developed to meet the demands of modern manufacturing, energy, and process industries, it integrates advanced control capabilities, robust hardware, and flexible configuration to optimize operational efficiency and scalability.

Key Features

• Modular hardware design enabling easy expansion and customization based on application requirements
• Support for multiple control architectures: centralized, distributed, or hybrid control strategies
• High processing power with multi-core CPUs, ensuring fast execution of complex control algorithms (e.g., PID, model predictive control)
• Seamless integration with industrial communication protocols (PROFINET, Modbus TCP, OPC UA, Ethernet/IP, HART)
• Redundant configurations (hardware and software) for mission-critical applications, minimizing downtime
• Built-in cybersecurity features to protect against unauthorized access and ensure data integrity
• Intuitive configuration and programming via industry-standard tools (e.g., Control Builder M), supporting IEC 61131-3 languages
• Wide operating temperature range (-20°C to 60°C) and ruggedized design for harsh industrial conditions

Technical Specifications

Application Areas

The AC 800M controller is widely deployed in industries such as:

Advantages

• Scalable design allows for system expansion without replacing core hardware

AC 800M ControllersPM891K01

The PM891 processor is a monolithic unit equipped with power supply, CPU-boards and unit termination. The unit contains microprocessor and RAM memory, a real-time clock, LED indicators, INIT push button and a Secure Digital interface. The PM891 does not contain any internal battery The PM891 has two RJ45 Ethernet ports (CN1, CN2) for connection to the Control Network, and one RJ45 serial port (COM4). The COM4 port is isolated and used for a configuration tool. The PM891 supports CPU redundancy for higher availability (CPU, CEX-Bus, communication interfaces and S800 I/O).

The communication expansion bus (CEX-Bus) is mounted on the unit. The CEX-Bus is used for extending the on-board communication ports with communication interface units. It is possible to use redundant communication interfaces on the CEX-Bus. The CEX-Bus Interconnection unit BC810 is used to increase the availability on the CEX-Bus by dividing it into separate segments. The optical Modulebus of the unit can be used for connecting seven clusters of S800 I/O units (each comprising up to 12 units). Each PM891 is provided with a unique Ethernet address which provides hardware identity to the unit.
