One Cable for Power and Data — The ECOFAST Hybrid Design

The 6XV1830-7AH10 is Siemens' PROFIBUS ECOFAST hybrid trailing cable — a single cable that simultaneously carries both the PROFIBUS DP fieldbus data connection and the power supply for the connected field devices. This "hybrid" design is the defining characteristic of the ECOFAST concept: instead of running separate power cables and PROFIBUS cables from the control cabinet to each field device, one ECOFAST hybrid cable handles both functions.

The cable construction reflects this dual role. Four 1.5mm² copper conductors carry the power supply current to field devices — the larger cross-section handles the current capacity required for device power. The two 0.64mm conductors carry the PROFIBUS DP differential data pair, individually shielded with overlapped aluminium foil and an outer braided screen of tin-plated copper. The PROFIBUS pair shielding isolates the data signal from the power conductors within the same outer jacket.

The trailing type designation confirms this cable is designed for dynamic installation — cable drag chains, moving machine arms, and applications where the cable flexes repeatedly during operation. Standard PROFIBUS cables are rated for fixed installation only; the trailing cable's flexible construction and strand geometry tolerate the mechanical bending cycles of moving installations without fatigue failure.

Key Specifications

Ordering and Installation Notes

The 6XV1830-7AH10 is sold by the metre with a minimum order quantity of 20 metres per delivery. Maximum continuous length per delivery is 1000 metres. Order the actual installed cable length plus routing allowance — the cable cannot be spliced mid-run in a standard PROFIBUS installation.

The violet outer sheath follows the PROFIBUS colour convention, distinguishing PROFIBUS cables from other industrial cable types in the cable duct. At 11mm outer diameter, verify the cable drag chain's minimum bend radius and fill ratio accommodate this cable specification before installation.

FAQ

Q1: What is the ECOFAST system and why does it use a hybrid cable?

ECOFAST (Energy and Communication Field Installation System) is Siemens' concept for distributing power and PROFIBUS DP communication to field devices in a single cable infrastructure, using standardised quick-connect connectors. The hybrid cable carries both functions in one sheath, reducing the cable count, conduit fill, and installation time compared to running separate power and PROFIBUS cables to each device.

Q2: Can the 6XV1830-7AH10 be used as a standard PROFIBUS cable without the power conductors connected?

Yes. The PROFIBUS data pair (2 × 0.64mm, shielded) functions as a standard PROFIBUS DP cable regardless of whether the power conductors are used. The power conductors can be left unconnected at both ends if the installation only requires the fieldbus data link. Terminate the unused power conductors appropriately at both cable ends to prevent contact with other conductors.

Q3: What is the maximum installation length per cable segment for PROFIBUS on this cable?

PROFIBUS DP segment length depends on baud rate and cable characteristics, not only the cable type. At 12 Mbps (maximum PROFIBUS DP speed), the maximum segment length is 100m. At 1.5 Mbps the maximum extends to 200m, and at lower baud rates further distances are possible. Confirm the specific baud rate used in the installation against the PROFIBUS DP segment length table for the 6XV1830-7AH10 cable type.

Q4: Is the 6XV1830-7AH10 suitable for installation in a cable drag chain (e.g., Igus)?

Yes — the "trailing cable" designation specifically identifies this cable as designed for drag chain and moving cable applications. The internal conductor stranding and outer jacket material are selected for the bending cycle fatigue resistance required in trailing cable applications. Confirm the drag chain manufacturer's minimum bend radius requirement against the cable's rated minimum bending radius.

Q5: What connectors are used with the 6XV1830-7AH10 at the field device end?

The ECOFAST system uses standardised circular quick-connect connectors at the field device end. Siemens' ECOFAST connector series mates to the ECOFAST-compatible field devices and I/O modules. The connector accommodates both the power conductors and the PROFIBUS data pair terminations in one connection. Order connectors separately based on the field device connection type (male or female, panel or cable).
