Description
ABB PM860K01 3BSE018100R1 AC800M
ABB PM860K01 3BSE018100R1 is the CPU main unit module of the AC800M modular controller in the ABB Compact Products 800 series, belonging to the PM860 series controller.
[Product Positioning]
AC800M is a compact programmable automation controller (PAC) in the ABB System 800xA automation system platform. PM860K01 is a standard CPU module for mid-range applications in this series, suitable for various industrial scenarios from basic logic operations to advanced process control. The I/O points can be expanded from a small number to thousands.

[Hardware Structure]
Adopting DIN rail installation method, the module consists of a detachable processor unit and a base. The CPU board integrates a power supply unit, CPU processor, and memory. The base realizes external connections between modules, including power supply and communication. There is a CEX communication expansion slot on the left side of the module, which can connect up to 12 communication modules.
Core Performance
The processor is a 32-bit RISC real-time multitasking microprocessor. The memory is 8 MB RAM, used to store firmware, control unit hardware configuration information, and application programs. Supports up to 16 tasks, with a minimum task cycle of 1 ms and an SOE (Sequential Event Recording) resolution of less than 1 ms. Equipped with a built-in watchdog timer, temperature detection, battery voltage monitoring, and error detection and correction functions.
[Communication Interface]
Integrate 2 IEEE 802.3 Ethernet interfaces (RJ45, CN1/CN2), can be set to redundant mode, with built-in redundancy switching program. Integrate two RS232C interfaces (RJ45, COM3/COM4), with COM3 having a modem control signal for long message transmission and COM4 being an isolated interface for connecting configuration tools. There are also Module Bus electrical and fiber optic expansion interfaces.
I/O expansion capability
Up to 12 S800 I/O modules (192 I/O points) can be connected through the Electrical Module Bus, and these 12 I/O families can be distributed and installed on two DIN rails. Seven S800 I/O clusters can be connected through the fiber optic Module Bus. Through Profibus DP fieldbus, more I/O clusters can be expanded and even remotely installed, supporting up to 98 remote stations. A single AC800M can manage thousands of I/O. The maximum distance for cables is 500 meters (500 Kb/s), and the maximum distance for multimode fibers is 2 kilometers (12 Mb/s).
Supported communication protocols
MasterBus 300、COMLI、Modbus、Siemens 3964R、Profibus DP、Foundation Fieldbus、EtherNet/IP、OPC Server（ Can communicate with third-party HMI and other systems. It also supports additional serial port protocols, suitable for connecting external devices such as terminals and printers.
Redundancy and Reliability
Supports CPU redundancy configuration with a switching time of less than 10 ms. RAM is backed up by an external battery to ensure data is not lost in case of power failure. The controller can be installed in a sealed cabinet without fans, openings, or air filtration, with an IP20 protection level and no need for an additional casing. Low energy consumption design, heat dissipation issues can be almost ignored.
Programming and Applications
Use ABB Compact Control Builder (Control Builder M) software for programming configuration, supporting all five programming languages of IEC 61131-3 standard (function block diagram, structured text, ladder diagram, sequential function diagram, instruction table). The application can be downloaded through a CF flash card or loaded into RAM via serial port or Ethernet. Support reusable code and library files for easy configuration and establishment of applications.
Comparison of AC800M Series
The AC800M series has five controller types to choose from: PM851, PM856, PM860, PM861, PM864, and PM865. PM860K01 belongs to the standard type, with higher configurations such as PM861 (16 MB RAM), PM864 (32 MB RAM), PM865 (high integrity security level) available for selection.
Typical application areas
Water/wastewater treatment, district heating, small and medium-sized power generation, discrete production lines, petrochemicals, mining, pulp and paper, cement and other process industries, as well as motion control scenarios such as robot control and motor drive.
