          PRODUCT DESCRIPTION

          PROFIBUS communication for distributed ET 200SP stations

          Siemens 6ES7155-6BU00-0CN0 is the IM 155-6 DP High Feature interface for SIMATIC ET 200SP. It connects a distributed station to PROFIBUS DP and supports up to 32 I/O modules, with Multi Hot Swap identified for this exact interface in Siemens' released-module documentation.

          The interface provides communication, identification and diagnostic functions for station integration. Siemens' 2019 bundle data sheet explicitly identifies this component and documents its PROFIBUS services and engineering options. The standalone interface is distinct from the complete bundle, so included accessories and delivered firmware require separate confirmation.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          ET 200SP PROFIBUS STATION INTEGRATION

          Plan the DP station around communication and address limits

          The IM 155-6 DP HF provides the PROFIBUS connection for an ET 200SP station rather than executing the controller's application program. Siemens identifies the complete 6BU00 article for up to 32 I/O modules and Multi Hot Swap. Keep that interface identity separate from PN variants and from the complete 6BA00 sales bundle when defining the station.
          Station planning also needs an address-space check. The interface reference allows up to 32 bytes per input and output module and 244 bytes per input and output station. Its PROFIBUS services include DPV0, DPV1, SYNC and FREEZE, while isochronous operation is not listed as supported. Review these distinct limits against the configured I/O requirements.
          Engineering options in the 2019 V3.1 reference include TIA Portal V13 SP1, STEP 7 V5.5 SP4 and higher, and the stated GSD revisions. Configuration control uses a data set, and I&M0 through I&M3 provide identification and maintenance data. Match the reference to the actual firmware and project before adopting its configuration options.

          Features:

          • Separate module-count and address checks
          • DPV0/DPV1 with SYNC and FREEZE
          • Firmware-aware engineering configuration
          The Siemens 6ES7155-6BU00-0CN0 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
          INTERCHANGEABILITY

          Verify the complete replacement identity before commissioning

          Start with the complete 6ES7155-6BU00-0CN0 order number and the installed interface's version information. The manufacturer distinguishes this component from the 6BA00 bundle containing a server module and a PROFIBUS connector. An interface-only purchase therefore requires an explicit check of the existing accessories and the items included in the replacement supply.
          Compare the existing project, I/O allocation and engineering environment before changing the interface. The data sheet's V3.1 reference is not proof of the firmware fitted to a spare. The historical Siemens tool matrix lists several 6BU00 firmware versions, so a matching family name does not establish identical firmware, configuration or update conditions.
          After the authorized replacement procedure, use the documented status and diagnostic facilities to assess the station, including RUN, ERROR, MAINT, PWR and DP indication. Multi Hot Swap is a supported feature, not a substitute for the missing installation procedure. Retain the applicable system safety instructions and verify communication through the engineering diagnostics before returning the station to service.

          Features:

          • Standalone interface versus bundle contents
          • Actual firmware and project comparison
          • Station diagnostics after authorized maintenance
          The Siemens 6ES7155-6BU00-0CN0 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about 6ES7155-6BU00-0CN0

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Is 6ES7155-6BU00-0CN0 the complete 6BA00 bundle?

            No. The Siemens bundle sheet lists 6BU00 as its interface module, alongside a 6ES7193-6PA00-0AA0 server module and a 6ES7972-0BB70-0XA0 PROFIBUS connector. Those accessories should not be assumed to accompany a standalone 6BU00 order; confirm the supplied items explicitly.

          • Does this interface use PROFIBUS or PROFINET?

            It is the IM 155-6 DP High Feature PROFIBUS interface. The documented interface uses RS 485 as a PROFIBUS DP slave, with a maximum transmission rate of 12 Mbit/s. The similarly named PN interface variants have a different network identity.

          • How should the station's module and address limits be checked?

            Check both limits independently. The exact 6BU00 interface is listed for up to 32 I/O modules. The 2019 interface reference additionally gives 32 bytes per input/output module and 244 bytes per input/output station; meeting the module count alone does not establish that the configured address allocation fits.

          • Which engineering references are documented?

            For the V3.1 reference, the 2019 sheet lists STEP 7 TIA Portal V13 SP1, STEP 7 V5.5 SP4 and higher, and GSD files for revisions 3 and 5 or higher. Compare these references with the actual device firmware and existing project rather than assuming every older device has the same software support.

          • Does Multi Hot Swap mean the interface can always be removed under power?

            No unconditional removal instruction follows from that feature name. Siemens identifies Multi Hot Swap for the exact interface, but the supplied functional sheet is not an installation procedure. Use the applicable system instructions and operational safeguards before performing any maintenance or module exchange.

          • What diagnostic information is provided locally?

            The reference lists status indication, alarms and diagnostics, with RUN, ERROR, MAINT, PWR and DP LEDs. These provide different status categories; interpreting a particular combination still requires the applicable device documentation and engineering diagnostics, not an assumed LED meaning from another interface.

          • Is firmware V3.1 guaranteed on the supplied module?

            No. V3.1 is the reference shown in the 2019 sheet, not a verification of the offered unit. Siemens' historical Automation Tool V3.1 matrix lists 6BU00 firmware versions V1.1, V3.0 and V3.1 for firmware-update support, so identify the actual device version before planning a replacement or update.
