The PM825-1 is a programmable logic controller (PLC) manufactured by ABB as part of ABB’s distributed control system. The PLC runs on the MC68360 microprocessor and performs operations in 16-bit mode and at 25MHz. The system and user applications are stored in 1024KB of FLASH, while 512KB of FLASH is used to store user applications, and 1024KB of RAM is used for system and user application execution

PM825-1 PLC is widely used in a variety of industrial automation scenarios, mainly including:
Motion control: The PM825-1 PLC is often used as a servo controller to control and manage motor motion for motion control applications such as robotic arms, conveyor belts and industrial machinery
Programming and configuration: Mainly used for programming, configuration, and diagnostics of the AC 80, but also as part of the AF 100 (Advant Fieldbus 100) network
Automated production line: It can be used to control the equipment on the automated production line to achieve automatic control and monitoring of the production process.
Remote monitoring and diagnosis: Supports multiple communication protocols and interfaces, such as Ethernet and serial ports, to facilitate remote monitoring, diagnosis, and configuration
User interface: including DriveWindow, Modbus protocol panel and printer, etc., easy for users to operate and troubleshoot
The characteristics of PM825-1 PLC include high reliability, powerful functionality, flexibility and easy maintenance, making it a core component in modern industrial automation control systems
