Function and Working Principle
The F3SP58-6S serves as the processing core of the FA-M3 PLC system. During operation, it continuously scans input signals, executes the user-defined ladder program, performs arithmetic and logical operations, updates internal memory, and refreshes output signals to control connected field devices.
Its high-speed processor and large memory capacity enable efficient execution of complex automation programs while maintaining deterministic system performance.
Operating Sequence
- Read input signals from digital and analog I/O modules.
- Execute the stored ladder logic program.
- Process timers, counters, arithmetic, and control instructions.
- Update internal memory and system registers.
- Refresh output modules.
- Repeat the scan cycle continuously.
