1. General Description

The 140CRP81100 is a single‑slot, hot‑swappable PROFIBUS‑DP master head module for the Schneider Electric Modicon Quantum PLC platform. It provides one PROFIBUS‑DP (DB9) port for controlling remote I/O and field devices, plus one RS‑232 (DB9) port for point‑to‑point serial communication. The module acts as a PROFIBUS‑DP master (Class 1) and supports S908‑over‑PROFIBUS RIO for Quantum remote I/O drops.

  • Connect shield to protective earth (PE) at one end only.

  • Enable 120 Ω termination at both physical ends of the PROFIBUS line.

5.2 RS‑232 (DB9 Male)

Standard EIA/TIA‑232; connect to DTE/DCE per device pinout.

6. Software Configuration

Supported software:
  • Unity Pro (recommended)

  • Concept v2.2+

  • Modsoft v2.32+

Configuration steps:
  1. Add module 140CRP81100 to I/O configuration.

  2. Set PROFIBUS parameters: baud rate, master address (0), slave addresses (1–31).

  3. Map DP slave I/O to Quantum memory (%I, %Q, %MW).

  4. Configure RS‑232 port (Modbus RTU/ASCII) if used.

  5. Download configuration to Quantum CPU.


7. Troubleshooting

  • PWR OFF: Check rack 24 VDC supply; reseat module.

  • RUN OFF: Configuration missing / invalid; re‑download project.

  • ERR ON: PROFIBUS short circuit, wrong termination, duplicate slave address, or baud rate mismatch.

  • COM no blink: No slaves on bus; check cabling and termination.


8. Certifications

  • CE (EN 55011, EN 61131‑2)

  • UL 508

  • CSA C22.2 No. 142

  • RoHS compliant

  • Class I Div 2 (hazardous locations)


9. Ordering Information

  • 140CRP81100: PROFIBUS‑DP Master + RS‑232, non‑coated (standard)

  • 140CRP81100C: PROFIBUS‑DP Master + RS‑232, conformal coated (harsh environment)
