Siemens Data Cable
Siemens PROFIBUS DP data cable (6XV1830 series) — shielded 2-core, 150 Ω, violet PVC sheath, 20 m length for reliable fieldbus communication and better noise immunity in industrial sites.
- This Siemens data cable is a PROFIBUS (DP) bus cable used for reliable communication between PROFIBUS devices such as PLCs, remote I/O, drives, and network components. It uses a screened construction (foil + braided shield) to help reduce electrical noise and maintain consistent signal quality on the bus.
- The cable’s 150 Ω characteristic impedance is an important PROFIBUS requirement—using the correct impedance helps avoid communication drops that can happen with mismatched cable types. The violet sheath makes PROFIBUS identification easier during installation and maintenance.

Benefits
- Stable PROFIBUS communication: correct impedance helps maintain predictable signal behavior on the bus
- Better noise immunity: foil + braided shield reduces EMI issues in industrial areas
- Faster troubleshooting: violet jacket helps identify the PROFIBUS line quickly
- Rugged PVC sheath: suitable for typical industrial routing and control cabinet environments
- Ready length: supplied as a 20 m cable for quick replacement or extension work
Why Choose
- Correct for PROFIBUS networks: designed around PROFIBUS impedance requirements instead of general-purpose data cabling
- Cleaner signal in noisy plants: shielding helps reduce interference from motors, VFDs, and power wiring
- Less downtime from wrong cable selection: using the correct bus cable reduces common issues like intermittent dropouts and unstable nodes
- Easier maintenance: consistent cable identification and known electrical characteristics help during expansions and repairs
FAQ
1) What is a Siemens data cable used for in PROFIBUS?
It’s used as the PROFIBUS bus line between nodes (PLC, I/O, drives) so data can be transmitted reliably across the segment.
2) What is the Siemens PROFIBUS cable specification I should check before buying?
Confirm it’s a PROFIBUS-rated cable with the correct impedance (150 Ω), shielding type, and suitable jacket for your environment.
3) Can I use a normal LAN cable instead of Siemens PROFIBUS data cable?
No—Ethernet/LAN cables have different impedance and construction. PROFIBUS requires the correct bus cable type to avoid communication issues.
4) How do I identify Siemens 6XV1830 PROFIBUS cable on an existing line?
Check the jacket marking/label if visible. If it’s not readable, share a photo of the cable and connector style for confirmation.
5) Does Siemens PROFIBUS data cable need shielding/grounding?
Yes—shielded PROFIBUS installations typically require proper shield termination practices to reduce noise and improve stability (follow your site standard/guideline).
6) What details should I send to confirm the right Siemens PROFIBUS cable?
Send the device list (PLC/I/O/drive models), existing cable photo/marking (if available), connector type, and required length.
