Installation Guide

1. Install 140XBE10000 backplane expander modules in the dedicated expansion slots of both Quantum racks to be connected.
2. Connect one end of the 140XCA71706 2-meter cable to the first 140XBE10000 module.
3. Connect the other end to the second 140XBE10000 module.
4. Ensure PROFIBUS connectors are fully seated and locked.
5. Verify rack communication via Unity Pro or Concept programming software.
6. For distances beyond 2 meters, verify maximum cable length specifications or consider fiber optic alternatives.

FAQ

Q: What does 140XCA71706 connect?
A: It connects two 140XBE10000 backplane expander modules installed in separate Modicon Quantum racks, extending the backplane bus between them.

Q: What is the maximum length?
A: The 140XCA71706 is 2 meters (6.56 ft). For longer distances, consult Schneider Electric for fiber optic or extended cable options.

Q: Can I use 140XCA71706 without 140XBE10000 modules?
A: No. The cable requires 140XBE10000 backplane expander modules at both ends to function properly.

Q: Is 140XCA71706 compatible with M580?
A: No. 140XCA71706 is designed for Modicon Quantum systems with 140XBE10000 expanders. M580 uses different backplane architecture (BMXXBE2005 + BMXXBCxxx cables).

Q: What connector type is used?
A: PROFIBUS connectors at both ends for industrial-grade, secure connection.

Selection Tips

• Quantum rack-to-rack backplane extension: 140XCA71706 (2m) + 2× 140XBE10000
• Always verify: Both racks have 140XBE10000 expander modules installed and available expansion slots
• Check cable routing: 2-meter length suitable for adjacent racks in the same cabinet
• For new installations: Consider BMXXBE2005 + BMXXBCxxx for M340/M580 platforms
