      Overview Manuals Common Applications Product Precautions
      Siemens 6DD1611-0AG0 is coupling memory module. It supplies dual-bus shared RAM so multiple SIMADYN D CPU modules can exchange configured process and communication data.
      • Provides two megabytes per bus
      • Connects to the L bus and C bus
      • Includes integrated bus termination
      • Supports battery-backed coupling data

      6DD1611-0AG0 operates with SIMADYN D module rack, first and second CPU modules, rack 3.4 V backup battery, configured coupling-memory connections.

      Engineered applications include Multi-CPU data exchange, SIMADYN coupling-memory service, Shared communications access, MM4 module replacement.

      Important Notice: Preserve the slot between the first and second CPUs, verify the rack battery, and retain the configured coupling connections and integrated bus-termination arrangement.

      Important Notice: The first document presents exact-model technical and engineering data. The second provides a separate installation, connection, commissioning and acceptance workflow.

      Multi-CPU data exchange
      Exchanges configured data between CPU modules.
      SIMADYN coupling-memory service
      Maintains the shared-memory path on both backplane buses.
      Shared communications access
      Supports multiple CPUs using an assigned CS7 serial interface.
      MM4 module replacement
      Restores the exact high-capacity coupling-memory position.
      Read the applicable Siemens instructions before work. Verify 6DD1611-0AG0 and the installed SIMADYN D digital control system configuration.
      1
      Verify the complete 6DD1611-0AG0 marking and the assigned SIMADYN D digital control system position before work.
      2
      Place the connected multi-cpu data exchange process in the approved maintenance state.
      3
      Isolate all applicable power and shared l-bus and c-bus coupling-memory data field energy before disconnection.
      4
      Record every connector, conductor, address, jumper and project identity before removal.
      5
      Use ESD controls and protect keyed interfaces, exposed contacts and electronic assemblies.
      6
      Confirm the installed SIMADYN D module rack and first and second CPU modules against the approved system record.
      7
      Restore power in a controlled sequence and review module, rack and host diagnostics.
      8
      Prove the intended simadyn coupling-memory service function and retain the final acceptance result.

      FAQS

      • Why is Siemens 6DD1611-0AG0 installed between CPU modules?
        The MM4 coupling memory must occupy a slot between the first and second CPUs so the documented multi-CPU data path is maintained.
      • How much memory does 6DD1611-0AG0 provide?
        It provides 2 x 2 MB of RAM, with 2 MB allocated to each of the L bus and C bus.
      • Which backplane buses connect to 6DD1611-0AG0?
        The MM4 connects to both the SIMADYN D L bus and C bus.
      • What battery dependency must be checked for 6DD1611-0AG0?
        Power-loss data backup uses the rack 3.4 V backup battery, so battery condition and replacement history must be verified.
      • What termination function is integrated in 6DD1611-0AG0?
        The module includes termination for both the C bus and L bus; preserve the intended rack topology.
      • When is 6DD1611-0AG0 required in a SIMADYN D rack?
        It is required when multiple CPU modules exchange configured data through coupling memory or share an assigned CS7 serial interface.
      • What does the system-fault relay on 6DD1611-0AG0 support?
        It provides the documented fault-signaling function for the coupling-memory arrangement and must be included in diagnostic checks.
      • How should 6DD1611-0AG0 be accepted after replacement?
        Verify battery backup, both bus connections, CPU communication and configured shared-data transfers without system-fault indications.
