Frequently Asked Questions (FAQ)

• Can I connect Pt100 sensors directly without an extra module?
  • Yes. The FX1S-14MT-001 has 4 built-in Pt100 (3-wire) inputs. No external temperature module needed.
• What is the maximum expansion I/O?
  • FX1S series supports up to 30 total I/O points using expansion blocks. This base unit already has 14 points.
• Does this PLC retain program after power loss?
  • Yes. EEPROM memory stores program permanently. No battery backup required. No maintenance for memory retention.
• Which software do I need to program it?
  • Use GX Works2 or GX Developer. Both fully support FX1S series, online editing and monitoring.
• What is the advantage of relay output versus transistor?
  • Relay output handles AC/DC loads up to 2A per point. Great for motors, solenoids, and contactors. Transistor output is faster for positioning.
• Can I use this for motion control with stepper drives?
  • Yes. MT models have built-in positioning (20kHz pulse output). Use external stepper drivers. Relay outputs are for auxiliary functions.
