Installation Guide

• Mount on standard DIN rail inside an IP20 cabinet.
• Use two SUB-D 9 cables to form a ring – connect IN and OUT ports.
• Keep total cable length under 12.8 km per segment.
• Use shielded twisted-pair cables for better noise immunity.
• Ground the shielding at one end only to avoid ground loops.

Debug & Maintenance Simplicity

• Green LED shows power and network activity.
• Red LED indicates fail-safe or ring break condition.

• Built-in fail-safe forces outputs to safe state on communication loss.
• Read diagnostic registers via Modbus function 08.
• Self-test mode verifies both SUB-D ports and internal logic.
• Error counter for CRC, framing, and overrun errors.

Frequently Asked Questions (FAQ)

• Q1: Can I use this adapter in a line (daisy‑chain) topology instead of ring?
• A1: No. The 170INT11003C is optimized for ring topology. For daisy‑chain, use other Momentum adapters.
• Q2: What happens if one device fails in the ring?
• A2: The fail-safe feature isolates the faulty node. The rest of the ring continues working.
• Q3: Maximum number of adapters in one ring?
• A3: Up to 254 adapters per segment. For larger networks, add repeaters or split into sub‑rings.
• Q4: Does cable type affect maximum distance?
• A4: Yes. Use low-capacitance shielded cable (≤ 40 pF/m) to achieve 12.8 km.
• Q5: Can I mix 170INT11003C with older Momentum adapters?
• A5: Yes, as long as all run at 500 kbit/s and use ring topology.

Experience-Based Buying Guide & Selection Tips

• Choose 170INT11003C for long-distance ring networks (over 2 km).
• For shorter runs with fewer devices, a cheaper daisy‑chain adapter may suffice.
• Verify your PLC supports 500 kbit/s ring communication (Modicon Momentum or Quantum).
• Buy extra SUB-D cables with proper shielding – generic cables reduce distance.
• Use a ring supervisor tool to monitor network health proactively.
• If you need more than 254 devices, install a second ring with a bridge.
• Keep spare adapters in stock – ring networks benefit from quick replacement.
