FAQ

• Q: What programming software is required? A: Yokogawa WideField3 programming software is used for development, debugging, and ladder logic download.
• Q: Does it support high-capacity SD cards? A: Yes, the SD slot is SDHC compatible for large-scale data logging and project backup.
• Q: Can direct I/O control be performed? A: Yes, besides the standard refreshing method, direct I/O instructions allow immediate action for time-critical signals.
• Q: Is this a refurbished unit? A: No, this is a 100% brand new original Yokogawa module with factory-certified hardware integrity.

Installation Guide

1. Power off the FA-M3 system completely before installation.
2. Insert the F3SP71-4S into the designated CPU slot on the base module.
3. Ensure the module is firmly seated and the locking mechanism is engaged.
4. Connect Ethernet and/or USB cables as required for your application.
5. Restore power and verify CPU status LEDs indicate normal operation.
6. Download and verify the sequence control program via WideField3.

Selection Tips

• Choose F3SP71-4S for large-scale applications requiring 60K-step program capacity and built-in Ethernet.
• For smaller systems, consider F3SP28-3S (8 MB memory, 4096 I/O points).
• Verify total 5V DC current consumption of all modules does not exceed the power supply rating.
• Use the SD card slot for data logging in SCADA-integrated applications.
