6. Installation Instructions

1. Power Off: Disconnect power to the Momentum I/O base.

2. ESD Protection: Use anti‑static wristband when handling the adapter.

3. Adapter Mounting: Align 171CCC96020 with the I/O base connector; press firmly until seated. Tighten mounting screws.

4. Ethernet Wiring: Connect CAT5e/CAT6 cable to the Ethernet port (10/100 Mbps auto‑sensing).

5. Power Up: Apply 5 V DC from the I/O base. Check LEDs: PWR ON, RUN blinking (program execution), LAN blinking (network activity).

6. IP Configuration: Use BootP Lite software to assign IP address, subnet mask, and gateway.

7. Programming: Download LL984 program via Concept, Modsoft, or ProWORX 32.

7. Compatibility

• I/O Bases: All Modicon Momentum discrete/analog I/O bases (170XTS series)

• Software: Concept ≥ V2.5 SR1, Modsoft ≥ V2.5, ProWORX 32/NxT (LL984 only)

• Network: Modbus TCP/IP compatible with standard Ethernet devices

8. Safety & Handling

• Installation/maintenance only by qualified personnel per local electrical codes.

• Disconnect power before wiring or maintenance to avoid electric shock.

• Avoid water, moisture, corrosive substances, and direct sunlight.

• Use ESD protection to prevent static damage to electronic components.

• Do not open the adapter casing; no user‑serviceable parts inside.

9. Maintenance & Troubleshooting

• Visual Inspection: Quarterly check for cracks, loose screws, or damaged connectors.

• Cleaning: Use dry, lint‑free cloth only; no solvents.

• Common Issues:

  • PWR Off: Check 5 V DC supply from I/O base.

  • FLT On: CPU fault; re‑seat adapter, reload program, check I/O base.

  • Ethernet Link Down: Verify cable, switch port, IP settings, and BootP configuration.

  • No Program Execution: Ensure LL984 program is downloaded and RUN mode is active.
