Description

The main unit of ABB PM856K01 AC800M series field controllers

Hardware configuration
Processor: High-performance processors are adopted, usually based on Intel Xeon technology. They have powerful computing capabilities and can quickly handle various complex control algorithms and logical operations. They support multi-task processing and parallel operations to ensure the real-time performance and stability of the system.
Memory: Equipped with 8M RAM for storing running programs and data. It also features a CompactFlash interface, allowing for the insertion of flash memory cards to store applications and data, achieving long-term data preservation and rapid reading.
Communication interface: The base plate has two RJ45 Ethernet ports (CN1, CN2), which are used to connect to the control network. It can be conveniently connected to the operator station, engineer station, management station or other devices that support Ethernet communication to achieve data exchange and remote monitoring. It also has two RJ45 serial ports (COM3, COM4), among which COM3 is an RS-232C port with a modem control signal and can be used to connect a modem or other devices with an RS-232C interface; COM4 is isolated and is used to connect configuration tools, facilitating the configuration and debugging of the controller.

Product characteristics
Modular design: It belongs to the family of rail-mounted modular controllers, which can be flexibly configured and expanded according to actual needs. Users can gradually add functional modules to meet the requirements of industrial automation control of different scales and complexities.
High reliability: It supports CPU redundancy function. When the main CPU fails, the backup CPU can automatically take over the work to ensure the continuous operation of the system and improve the availability of the system. It has an IP20 protection level at the same time, can adapt to various industrial environments, and has passed comprehensive EMC certification, enabling stable operation in complex electromagnetic environments.
Easy to configure: It can be configured through the 800xA control builder, which is convenient to operate and can simplify the development and debugging process of the system.
