Function and Working Principle
The F3XD64-3F continuously monitors the ON/OFF status of connected field devices and transmits this data to the FA-M3 PLC CPU.
Each input channel is electrically isolated using photocouplers to ensure stable operation in noisy industrial environments. During each scan cycle, the PLC reads input status, executes control logic, and updates system outputs accordingly. The module supports configurable sampling times and interrupt processing for high-speed event detection.
Operating Sequence
- Receive digital signals from field devices
- Detect ON/OFF status changes
- Convert signals into digital input data
- Transfer data to PLC CPU
- Execute control program
- Repeat continuously
