6. Installation Instructions
Power Off: Disconnect power to the Momentum I/O base.
ESD Protection: Use anti‑static wristband when handling the adapter.
Mounting: Align 171CCC98020 with the I/O base connector; press firmly until seated. Tighten screws.
Wiring:
Ethernet: Connect CAT5e/CAT6 to RJ45 port (10/100 Mbps auto‑sensing).
RS‑485: Connect 2‑wire shielded cable to Modbus terminals.
Power Up: Apply 5 V DC. Check LEDs: PWR ON, RUN blinking (program execution), LAN/MBUS blinking (activity).
IP Configuration: Use BootP Lite or EcoStruxure Control Expert to set IP, subnet, gateway.
Programming: Download LL984 program via Modsoft, Concept, or ProWORX 32.
7. Compatibility
I/O Bases: All Modicon Momentum discrete/analog I/O bases (170XTS series)
Software: Modsoft ≥ V2.5, Concept ≥ V2.1, ProWORX 32/NxT (LL984 only)
Network: Modbus TCP/IP (Ethernet), Modbus RTU/ASCII (RS‑485)
8. Safety & Handling
Installation/maintenance only by qualified personnel per local codes.
Disconnect power before wiring/maintenance to avoid electric shock.
Avoid water, moisture, corrosive substances, direct sunlight.
Use ESD protection to prevent static damage.
Do not open casing; no user‑serviceable parts inside.
9. Maintenance & Troubleshooting
Inspection: Quarterly check for cracks, loose screws, damaged connectors.
Cleaning: 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, BootP.
Modbus No Response: Check RS‑485 wiring, baud rate, slave address.
No Program Execution: Ensure LL984 program is downloaded and RUN mode active.
