ABB AC 800M Controller Hardware

ABB AC 800M Controller Hardware

Product overview

AC 800M Overall: It is a configurable and programmable hardware platform that becomes an AC 800M or AC 800M HI controller after configuration programming, including hardware units such as processor units and high integrity processor units. It can be used as an independent process controller or perform local control tasks in a control network, supporting multiple I/O system connections, requiring firmware loading and application creation using Control Builder M. It is suitable for various applications ranging from small PLCs to advanced DCS. The AC 800M HI controller can run non SIL and SIL classification applications.

Processor unit:

PM8xx/TP830: Composed of a processor unit and a base, the CPU board contains a microprocessor, etc. The power board generates power, and the base has multiple connections. In a single CPU configuration, S800 I/O clusters can be directly connected, and CEX Bus can expand communication ports.

PM891: High performance controller, connected to S800 I/O system through optical Modulus, can run independently or in control network, supports redundant configuration, has multiple interfaces and connectors, including redundant links.

Redundancy: PM861 and other processor units support redundancy, and the controller contains two processor units, one as the main and one as the backup. In case of failure, seamless switching is required, and the system can restore redundancy after replacing the faulty unit. PM86x/TP830 and PM891 each have their own characteristics in redundant configuration.

High integrity: AC 800M can be configured for safety critical applications, with main components such as PM865. PM865 has enhanced internal diagnostics, while SM810 and SM811 each have their own characteristics. The high integrity system's Module Bus telegram uses the concept of long frames.

Control software: It is the generic name for the functions of a controller, consisting of hardware, firmware, and application program functions, and requires the Control Builder M tool to create applications.

Ethernet address: The TP830 base and PM891 unit of PM8xx (excluding PM891) both have unique Ethernet addresses.

Key features: modularity, easy installation, convenient troubleshooting, protection level, EMC certification, support for multiple I/O and communication protocols, battery backup, CPU redundancy, etc.

Product release history: lists the new content and corresponding user documentation for each version of AC 800M.
