Siemens 6ES7195-7HD10-0XA0 SIMATIC DP Bus Module

Configured for holding two redundant IM153-2 interface modules in SIMATIC DP ET 200M distributed I/O systems, the Siemens 6ES7195-7HD10-0XA0 (Siemens 6ES7195-7HD10-0XA0 Bus Module) provides direct physical and electrical execution of hot-swapping maneuvers during RUN operating time.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and Backplane Continuity

The 6ES7195-7HD10-0XA0 acts as the dedicated active backplane backbone that establishes continuous electronic paths for localized sub-networks. When linked upstream to Profinet or PROFIBUS DP deterministic networks via the IM153-2 interface cards, this module sustains synchronous backplane bus communication velocity across all downstream I/O modules. It prevents signal attenuation or timing jitter during runtime operations. By implementing isolated electrical traces between the dual interface module slots, the hardware allows one IM153-2 to fail or be extracted while the secondary redundant card maintains uninterrupted deterministic network data exchanges with the master controller.

Frequently Asked Questions

Q: Does extracting one of the two installed IM153-2 modules during RUN mode break the backplane communication to the downstream I/O slices?

A: No. The internal circuitry of the module isolates each interface slot, allowing the active redundant IM153-2 to maintain continuous communication with the downstream I/O backplane bus without interrupting process data flow.

Q: What are the backplane current load limitations imposed by this module?

A: This component functions as a passive physical routing and connection matrix; it does not consume active current from the system backplane, but it is limited by the maximum bus current passing throughput specified by the SIMATIC ET 200M platform.

Q: Can standard 40 mm wide digital or analog I/O modules be installed directly onto this specific bus module?

A: No. The mechanical footprint and internal connector pinout of the 6ES7195-7HD10-0XA0 are engineered exclusively to accept up to two IM153-2 interface modules for redundant setups.

Field Installation Guidelines

• Active Bus Rail Mounting: Mount the unit exclusively on the designated active bus module rail. Lower the top rear hook onto the rail guide and slide the unit laterally into engagement with the adjacent module connector.
• Grounding Requirements: Secure a solid functional ground connection via the DIN rail mounting mechanism to ensure proper shielding execution against electrical noise across the PROFIBUS DP backplane bus links.
• Module Insertion Alignment: Align the rear pins of the IM153-2 interface module perpendicular to the bus module face before seating the hardware. Do not insert modules at an angle, as this can cause permanent mechanical deformation of the backplane bus connection pins.
