ABB PM861AK01 core processor module

ABB PM861AK01 core processor module

ABB PM861AK01 is a core processor module in ABB’s AC800M automation control system with part number 3BSE023601R1.

Performance parameter
Processor performance: Equipped with high-performance 32-bit processor, clock frequency up to 400MHz, strong data processing ability, can quickly process complex control algorithms and logic operations, to ensure that the system responds to various changes in the industrial production process in real time.
Memory configuration: 256MB of SDRAM for program execution and data processing, and 128MB of flash memory for program storage, providing enough space to run large, complex automated programs.

Communication capability
Ethernet interface: Provides 3 Ethernet interfaces, supporting Ethernet TCP/IP, Modbus TCP and other industrial Ethernet protocols, can be with the host computer, human-machine interface (HMI), other controllers and other equipment high-speed data communication and networking, to achieve the construction of distributed control system.
Fieldbus interface: Supports fieldbus protocols such as PROFIBUS DP and DeviceNet, which can connect various field devices such as sensors and actuators for comprehensive monitoring and control of industrial sites.

Functional characteristics
Programming language support: It supports five programming languages specified by IEC 61131-3, including ladder diagram (LD), function block diagram (FBD), structured text (ST), sequential function diagram (SFC), instruction table (IL), so that engineers can choose the appropriate programming method according to different application requirements.
Redundancy: Supports hot-swappable redundancy, including power supply redundancy, communication redundancy, and CPU redundancy. When a system fault occurs, the system automatically switches to the standby device to ensure uninterrupted system running and improve system reliability and availability.
Diagnostic function: With a comprehensive self-diagnosis function, real-time monitoring of module operating status, hardware failure, communication failure, etc., and through the indicator light and system alarm feedback to the operator, easy to quickly troubleshoot and solve problems.

Application field
Widely used in power, chemical, metallurgy, paper, food and beverage and other industrial automation fields, can achieve process control, motion control, logic control and other automation tasks.
