ABB PM856K01 high-performance programmable automation controller module

ABB PM856K01 high-performance programmable automation controller module

The PM856K01 is a high-performance Programmable Automation controller (PAC) module in the ABB AC800M family with part number 3BSE023736R1.

Performance parameter
Processor: It is equipped with a high-performance 32-bit processor, the main frequency of up to 200MHz, can quickly handle complex control algorithms and logic operations, real-time response to various changes in the industrial process.
Memory: With 128MB of SDRAM for program execution and data processing, and 64MB of flash memory for program storage, there is plenty of space to run large, complex automated programs.

Communication capability
Ethernet interface: Provides three Ethernet interfaces that support a variety of industrial Ethernet protocols, such as Ethernet TCP/IP and Modbus TCP. It can easily communicate and network with other devices, such as upper computer, human-machine interface (HMI), other controllers, etc., to realize the construction of distributed control system.
Fieldbus interface: Supports PROFIBUS DP, DeviceNet and other fieldbus protocols, and can connect various types of field devices, such as sensors, actuators, etc., to achieve comprehensive monitoring and control of industrial sites.

Functional characteristics
Programming language: supports a variety of international standard programming languages, such as the five programming languages specified by IEC 61131-3 (ladder diagram LD, function block diagram FBD, structured text ST, sequential function diagram SFC, instruction table IL), which is convenient for engineers to 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 the system fails, it can automatically switch to the standby device to ensure the uninterrupted operation of the system and improve the reliability and availability of the system.
Diagnostic function: It has a comprehensive self-diagnostic function, which can monitor the running status of the module in real time, hardware faults, communication faults, etc., and timely feedback to the operator through the indicator light and system alarm, which is easy to quickly troubleshoot and solve problems.

Application scenario
Widely used in all kinds of industrial automation fields, such as power, chemical, metallurgy, paper, food and beverage industries, can be used to achieve process control, motion control, logic control and other automation tasks.
