Backplane Bus Communication Velocity and Deterministic Networks

The 6ES7195-7HB00-0XA0 acts as the passive physical link required to route the ET 200M backplane bus communication signals between adjacent modules. By securing this bus continuity, it enables the high-speed, deterministic transmission of data over Profinet or Profibus DP networks back to the central controller. The mechanical design enforces precise pin alignment across the internal backplane connection, minimizing propagation delays and preventing bit transmission errors caused by physical shifting. This precise alignment guarantees that firmware flash compatibility routines and diagnostic queries can execute uninterrupted across all seated I/O slices.

Frequently Asked Questions

Q: Can this bus module be mixed with other widths of ET 200M bus modules on the same active backplane rail?

A: Yes. The module can be installed alongside other ET 200M active bus modules on the standard DIN rail designed for hot-swapping configurations, provided total backplane current draw limits are maintained.

Q: What are the restrictions regarding the insertion and removal function supported by this module?

A: The removal and insertion (hot-swap) functionality is supported when utilized within a configured ET 200M system. However, peripheral modules must be extracted straight out to avoid bending the physical backplane pins housed within the 6ES7195-7HB00-0XA0 structure.

Q: Does this passive component require a separate external 24 VDC power connection?

A: No. The unit does not possess external power terminals; it derives and passes control voltage solely via the integrated backplane bus connectors from the upstream IM 153 interface module.

Field Installation Guidelines

  • Rail Alignment: Mount the bus module exclusively onto the dedicated ET 200M active bus rail. Slide the module onto the rail laterally until it locks firmly with the adjacent backplane element.
  • Shielding and Grounding: Ensure that the DIN rail itself is connected to the central functional earth (FE) ground bar via a low-impedance copper strap to mitigate high-frequency electromagnetic noise.
  • Module Insertion: When installing the 40 mm I/O modules into this bus module, align the module top hooks first, then swing the bottom inward until the rear pins seat completely into the bus module sockets. Fasten the integrated module screws to prevent vibration-induced disconnects.
