5 Professional FAQ – Experience & Selection Guide

• Q: Can this module replace a failed FM 455 C directly?
• A: Yes, same order number. Check your firmware version – we can verify compatibility.
• Q: Do I need external temperature compensation?
• A: Internal compensation is sufficient for most cases. Use external Pt100 for high precision.
• Q: What is the typical update rate for 16 loops?
• A: Depends on integration time – at 20ms integration, approx. 50ms per loop. We can optimize.
• Q: Can I use unshielded cables for digital inputs?
• A: Yes, up to 600m. For analog and TC, always use shielded.
• Q: Which S7‑400 CPUs work best with this module?
• A: CPUs with sufficient process image and memory – e.g., 416‑2, 417‑4. We can advise.
