Frequently Asked Questions

• Can I use this controller without expansion modules?
  • Yes, it works standalone with its 20 built‑in I/O points.
• What software do I need to program it?
  • Use TwidoSuite (free download) or EcoStruxure Machine Expert.
• Does it support PID control?
  • Yes, built‑in PID function is available – great for temperature/pressure.
• Is the analog input isolated?
  • No, but it is protected and has 100 kΩ impedance.
• What happens if power fails?
  • Internal lithium battery keeps RAM safe for 30 days.

Purchase Guidance – Pro Tips

• Need fast counting? – Use inputs I0.0/I0.1 (20 kHz, 32‑bit).
• For PWM output – use Q0.0 or Q0.1 (7 kHz capability).
• Extra memory? – add a 32K cartridge in the free slot.
• Remote monitoring? – use the RS485 port for Modbus networking.
• Spare parts – keep a HE‑10 connector kit in stock.
