Siemens 6ES7195-7HC00-0XA0 PLC Module

The Siemens 6ES7195-7HC00-0XA0, also cataloged as the 6ES7195-7HC00-0XA0 Bus Module, operates as a dedicated hardware component for active backplane bus segmenting within Siemens SIMATIC ET 200M distributed I/O systems. The 80 mm wide structural backplane rail interface holds standard expansion components, facilitating uninterrupted parallel data transmission across adjacent rack slots while managing live electrical connection transitions.

Hardware Specifications

Siemens ET 200M Architecture Integration

• Profinet / EtherNet/IP Deterministic Networks Connection Stability: The bus module forms a continuous local communication grid when connected to IM 153 interface stations. By routing internal signal layers at full hardware rates, it maintains bit-stream stability up to remote head stations linked to wide-area Profinet / EtherNet/IP deterministic networks.
• I/O Density Scaling Hot-Swap Control: The module breaks down the legacy passive backplane line layout into isolated, active hardware slices. This architecture permits extensive I/O density scaling configuration blocks, allowing operators to extract or insert individual 80 mm signal nodes without dropping the localized subrack network or disrupting neighboring register blocks.

Frequently Asked Questions

Q: How does the removal and insertion (hot-swap) safety routine function mechanically on this unit?

A: The bus module contains an independent, active backplane bypass circuit array. When an 80 mm wide I/O module is unseated from the front connector pins, the underlying active bus module closes a series of parallel solid-state switches, routing the main system bus traffic around the empty slot to preserve data execution across remaining channels.

Q: Can standard S7-300 subracks accommodate the 6ES7195-7HC00-0XA0 bus module directly?

A: No. Standard aluminum S7-300 DIN rails lack the mechanical recess tracks required to mount this component. Active hot-swap bus modules must be seated exclusively on the specialized Siemens active backplane rail structure, which aligns the bus elements side-by-side into a continuous parallel electrical block.

Field Installation Guidelines

• Chassis Layout Alignment, Clearance Constraints, and Mechanical Seating: Hook the top lip of the 80 mm bus module onto the active backplane rail tracking line, then pivot the assembly downward until the physical side locks click together. Slide successive modules laterally until the parallel multi-pin connectors mate securely. Maintain a 40 mm vertical spacing margin to allow air tracking over installed modules.
• Conductor Separation, Wireway Constraints, and Shield Grounding: Route all signal leads coming off the attached I/O faceplates through panel wire channels separate from three-phase AC distribution cabling and motor drive links. Ensure the structural backplane metal rail is bonded directly to the enclosure main copper grounding bar via a heavy, low-impedance conductor to dissipate transient noise fields.
