Product Specifications

Technical details and manufacturing context for PLC Processor

Definition
The PLC Processor is the core computational component within a Programmable Logic Controller (PLC) system. It is responsible for executing the user-defined control program stored in memory, performing logical operations, arithmetic calculations, timing, and sequencing functions. The processor continuously scans inputs from connected sensors and devices, processes the control logic, and updates outputs to actuators and other field devices, thereby automating industrial machinery and processes within the broader Control System (PLC/Drive) architecture.
Working Principle
The PLC Processor operates on a cyclic scan basis. Each scan cycle consists of three main phases: 1) Input Scan: Reads the current state of all input modules. 2) Program Execution: Executes the user program stored in memory, using the input data and internal variables to perform logic, math, and control instructions. 3) Output Scan: Updates the state of all output modules based on the results of the program execution. This scan cycle repeats continuously, allowing for real-time control of industrial processes.
