3. LED Indicators (Front Panel)
PWR (Green) – ON: Module power OK
RUN (Green) – ON: Module active / operational
COM (Green, Blinking) – PROFIBUS communication activity
ERR (Red) – ON/Blink: Fault (comm loss, config error, duplicate address)
4. Installation
Power OFF the Quantum rack before inserting the module (hot‑swap allowed in normal operation).
Insert 140CRP81100 into any single slot; push firmly until latched.
Power ON the rack; verify PWR and RUN LEDs are ON.
5. Wiring & Pinout
5.1 PROFIBUS‑DP (DB9 Male)
| Pin | Signal | Description |
|---|---|---|
| 1 | — | Not used |
| 2 | — | Not used |
| 3 | RxD/TxD+ | Data + |
| 4 | — | Not used |
| 5 | GND | Ground |
| 6 | +5 V | Termination power (optional) |
| 7 | — | Not used |
| 8 | RxD/TxD− | Data − |
| 9 | — | Not used |
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)
6. Software Configuration
Unity Pro (recommended)
Concept v2.2+
Modsoft v2.32+
Add module 140CRP81100 to I/O configuration.
Set PROFIBUS parameters: baud rate, master address (0), slave addresses (1–31).
Map DP slave I/O to Quantum memory (%I, %Q, %MW).
Configure RS‑232 port (Modbus RTU/ASCII) if used.
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.
