1 × 75Ω Coaxial Port, Conformal Coated, 2‑Slot

English Datasheet / Instruction Manual (Full Text)

1. General Description

140CRP93100C is a 2‑slot, hot‑swappable S908 RIO head‑end adapter with conformal coating for the Schneider Electric Modicon Quantum PLC platform. It acts as the local CPU interface (RIO Master) for the S908 remote I/O network, connecting the Quantum CPU to remote I/O drops via single 75Ω coaxial cable. It works with 140CRA93100 / 93200 / 93100C remote adapters and supports up to 31 RIO drops per network.

7. Software Configuration

Supported software:

  • Unity Pro (recommended)

  • Concept v2.2+

  • Modsoft v2.32+

Configuration steps:

  1. Add 140CRP93100C (2 slots) to I/O configuration.

  2. Enable S908 RIO master function.

  3. Set drop addresses: 1 … 31

  4. Map remote I/O (%I, %Q, %MW) to Quantum memory.

  5. Download configuration to CPU.

8. Troubleshooting

  • PWR OFF: Check 24 VDC backplane; reseat module.

  • RUN OFF: Missing/invalid config; re‑download project.

  • ERR ON: Wrong termination, cable short, duplicate drop address, or baud mismatch.

  • COM no blink: No drops on bus; check cabling/termination.
