      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • SS5 is distinct from the SS52 PROFIBUS-DP/MPI execution, so the bus protocol must be matched to the fitted submodule.
      Product type: SS5 PROFIBUS-FMS Submodule
      Product series: SIMADYN D
      Submodule designation: SS5
      Siemens 6DD1688-0AE0 is the SS5 communications submodule for a SIMADYN D CS7 support module. It provides a master interface for PROFIBUS-FMS, also known as SINEC L2-FMS. FMS uses service-oriented client/server communication. SS5 is distinct from the SS52 PROFIBUS-DP/MPI execution, so the bus protocol must be matched to the fitted submodule.

      The CS7 support module, communications submodule and selected receptacle are configured in HWConfig. Up to three communications submodules can be fitted to one CS7, while CPU data exchange uses the 16 kbyte dual-port RAM located on the support module. Connector X5 provides the electrically isolated RS485 PROFIBUS interface and an isolated 5 V supply for an Optical Link Module.

      SS5 operation requires a COM database generated with COMSS5 and loaded into the submodule. The legacy tool runs on a suitable S5-DOS programmer or PC arrangement. The bus connector or terminal supplies switchable terminating resistors; cable layout and drop capacitance must suit the baud rate. Ground the cable screen over a large contact area at cabinet entry and preserve front-panel bonding to CS7. CS7 diagnostic LEDs distinguish missing database, initialization and bus activity.
      Controller platform reference: SIMADYN D. Match the installed hardware and configuration.
      Technical downloads for Siemens 6DD1688-0AE0: a manufacturer technical excerpt and an Apter Power installation and commissioning guide.
      The technical reference preserves selected manufacturer pages. The installation guide is compiled by Apter Power for preparation and review; apply the original operating procedures and site controls during work.
      System integration: Match the CS7 support, selected receptacle and HWConfig configuration.

      Application scope: SS5-specific FMS data applies to 6DD1688-0AE0. The 16 kbyte dual-port memory belongs to CS7; SS52 DP/MPI and RS232 functions are separate.
      Match 6DD1688-0AE0 to the installed hardware and approved configuration before replacement or commissioning.
      Protocol selection

      Match the SS5 FMS execution; do not substitute SS52 DP/MPI behavior.

      CS7 integration

      Match the CS7 support, selected receptacle and HWConfig configuration.

      Database and bus wiring

      Retain the COMSS5 database and verify bus termination, screen bonding and the X5 connection.

      Communication acceptance

      Check initialization and CS7 diagnostic indications, then validate the expected client/server data exchange.

      Protect the hardware

      Use the applicable isolation and electrostatic-discharge controls. Preserve connectors, identification and mechanical retention during handling.

      Verify the restored function

      Apply the approved site acceptance procedure and compare actual behavior with the recorded system configuration before returning equipment to service.

      Alternative Names

      Technical notes

      System relationship: Match the CS7 support, selected receptacle and HWConfig configuration.

      Applicability: SS5-specific FMS data applies to 6DD1688-0AE0. The 16 kbyte dual-port memory belongs to CS7; SS52 DP/MPI and RS232 functions are separate.

      FAQ View All FAQ

      • Which protocol does 6DD1688-0AE0 support?
        The SS5 execution provides a PROFIBUS-FMS / SINEC L2-FMS master interface.
      • Is 6DD1688-0AE0 the SS52 DP/MPI submodule?
        No. SS5 and SS52 have different protocol roles; the SS52 DP/MPI functions do not establish SS5 capability.
      • Which support module accepts 6DD1688-0AE0?
        It plugs into a CS7 communications support module.
      • How many communications submodules can share the CS7 used by 6DD1688-0AE0?
        Up to three can be fitted, with each receptacle configured appropriately.
      • Where is the dual-port RAM used by 6DD1688-0AE0?
        The 16 kbyte dual-port RAM used for CPU data exchange is on the CS7 support module.
      • Which interfaces are available at X5 on 6DD1688-0AE0?
        X5 provides isolated RS485 PROFIBUS and an isolated 5 V supply for an Optical Link Module.
      • Which configuration database does 6DD1688-0AE0 require?
        A COM database must be generated with COMSS5 and loaded into SS5.
      • How is bus readiness assessed for 6DD1688-0AE0?
        Use the associated CS7 LEDs to check initialization and database state, then verify actual bus activity and the configured data exchange.
