Siemens 6DD1600-0AJ0 SIMADYN D PM5 CPU Module
01Product Overview
Siemens 6DD1600-0AJ0 is the SIMADYN D PM5 CPU module for general open-loop and closed-loop control tasks in a legacy SIMADYN D station. The module uses a 32 MHz 32-bit RISC processor, 4 MB EDO DRAM, and 64 KB battery-backed SRAM, and it loads the user program from an MS5 or MS51 program memory module.
02Functions
Core Functions
- Executes general closed-loop and open-loop control functions in a SIMADYN D station.
- Loads and expands the user program from an inserted MS5 or MS51 program memory module during initialization.
- Exchanges data with other station modules over the SIMADYN D subrack backplane.
- Provides up to eight binary inputs and optional connections for two absolute and two incremental encoders.
- Stores operating-system diagnostics, configured SAV process quantities, and selected message or trace data in battery-backed SRAM.
- Supports online loading through the serial engineering connection or offline programming of the memory module with the documented adapter workflow.

04Compatibility
- Use only in the documented SIMADYN D subrack, power, backplane, memory-module, and I/O architecture.
- Match the complete STEP 7 / HW Config and CFC project, software versions, program library, cycle structure, and compiled memory-module content.
- Preserve the MS5 or MS51 program module and verify that it contains the correct user program for the target station.
- Confirm encoder type, signal assignment, binary inputs, subrack slot, neighboring modules, backplane communication, and serial engineering path.
- Verify the subrack or external battery because the 64 KB SRAM relies on backup power for retained diagnostics and process data.
- Siemens states no replacement; migration to another controller requires functional re-engineering and validation.
05Applications
Typical Uses
- Legacy high-speed control loops originally engineered on SIMADYN D.
- Drive, test-stand, process, and machinery control requiring deterministic legacy function-block execution.
- Encoder-based control using the PM5 absolute or incremental encoder connections.
- Like-for-like repair of a documented SIMADYN D station.
- Migration projects that first require recovery and functional documentation of the existing PM5 application.
Selection Boundary
- Use application examples only as engineering context; they do not prove compatibility with an installed machine.
- Confirm electrical, mechanical, network, software, safety, environmental, and lifecycle requirements against the complete project.
- Preserve configuration records and perform controlled commissioning whenever hardware is exchanged.
06Lifecycle
- The article has reached End of Product Lifecycle and the official record states no replacement.
- Back up the engineering project, libraries, compiled program, MS5/MS51 contents, station configuration, parameters, trace data, and diagnostics.
- Record every subrack slot, module article, wiring point, encoder, cycle, communication link, battery condition, and machine interlock.
- After exchange, verify memory-module recognition, station startup, backplane communication, binary inputs, encoders, cycle execution, retained data, diagnostics, and control response.
- Run controlled open-loop and closed-loop tests against the approved baseline before returning the system to service.
- A platform migration requires a functional specification, signal map, control-loop validation, and an approved commissioning plan.
FAQFrequently Asked Questions
What is 6DD1600-0AJ0?
6DD1600-0AJ0 is an end-of-life SIMADYN D PM5 CPU module using a 32 MHz 32-bit RISC processor and MS5/MS51 program memory.
Where is this product normally used?
It is used for legacy high-speed open-loop and closed-loop control in a SIMADYN D station.
What must be checked before ordering?
Confirm the complete article number, installed hardware revision, lifecycle state, supply and I/O design, communication interfaces, connector assignment, software release, approvals, and project configuration.
What information should be saved before replacement?
Save the full STEP 7/HW Config and CFC project, libraries, compiled memory module, station layout, parameters, cycles, encoders, wiring, traces, diagnostics, and battery condition.
Can a similar Siemens article be used as a direct replacement?
No. Siemens states no replacement; another controller requires functional re-engineering, new hardware and software design, and full validation.
What should be verified after installation?
Verify memory loading, station and backplane startup, binary and encoder inputs, cycles, retained data, diagnostics, communications, interlocks, and every control loop.
