The Siemens 6DD1600-0AK0 is a PM6 RAPID 64‑bit CPU module engineered for the SIMADYN D high‑performance distributed control platform. This 6DD1600-0AK0 processing unit is powered by a 64/128 MHz RISC processor, delivering deterministic real‑time performance – achieving a 0.1 ms minimum cycle time and configuring a typical control loop in roughly 0.5 ms. Integrated with 8 MB of DRAM, 256 KB of battery‑buffered SRAM, 8 onboard binary inputs (four interrupt‑capable), plus L‑bus and C‑bus support, the 6DD1600-0AK0 functions as the high‑performance heart of any SIMADYN D rack, built for open‑ and closed‑loop tasks with extreme computational demands.
Turbine Control Systems: Steam/gas turbine governing (including synchronisation, speed and load control, thermal‑stress monitoring), as used in Bobov dol, Varna and Maritza east 2 TPP projects (Siemens‑Germany main contractor, 2001) with fully redundant (reserved) dual‑controller fail‑safe designs
Drive Control & Heavy Industry: Multi‑axis synchronisation for rolling mills (e.g. Handan Steel CSP hot continuous rolling mill automatic roll change system, 2009), printing presses, winding lines
Motion Control & Machine Tools: High‑speed, precision positioning for CNC axes, servo actuators, robotics
Process Automation: Refineries, chemical reactors, pharmaceutical batch processing, food and beverage plants
Factory Automation: Large assembly lines, packaging machinery
RISC‑processor based architecture with 64‑bit / 128 MHz operation and 32/64‑bit hybrid capability
Extremely short min. cycle time (0.1 ms); typical control loop configuration ≈0.5 ms
8 MB of DRAM (program & data) + 256 KB of battery‑buffered SRAM (retains OS error diagnostics + up to 1000 configured process quantities via the SAV function block)
L‑bus and C‑bus versatility: each independently usable for different transponder addresses (receiver ID + channel number), fixed byte count per frame, selectable bus connection via C‑BUS jumper (L‑bus = up to 32 bytes/cycle; C‑bus = up to 28 bytes/cycle)
8 onboard binary inputs (24 V DC) – maximum 4 usable for interrupt tasks, rest as standard inputs
RS‑232 (V.24, DUST1 protocol at 19.2 kbaud) serial service interface for commissioning/testing (connector X01)
Optional PROFIBUS-DP interface via external modules (6DD1640-0AC0 – 12 Mbps)
7‑segment display for CPU number (1‑8) in normal operation and error letters for diagnostics
Free configuration using SFC / CFC (Step‑7) or STRUC G/STRUC L (Unix‑based)
Online program loading via serial connection to PC; offline loading via PCMCIA card on programming adapter
Processes CPU‑intensive control tasks requiring extremely high computational performance or very large user programs; executes both open‑loop and closed‑loop functions with deterministic timing.
Exchanges data via the L‑Bus (local bus, up to 32 bytes/cycle) and C‑Bus (communication bus, up to 28 bytes/cycle) for distributed rack‑level coordination.
Stores and retrieves the user program from an external MS5‑series memory module (MS51, MS55 etc.) inserted in the CPU's own module receptacle.
Supports two program‑loading methods: offline (via PCMCIA card on a PC programming adapter) and online (directly via serial RS‑232 connection).
Accepts 8 binary input signals (24 V DC) via the 10‑pin connector X5. Up to 4 of these inputs can be used to call up interrupt tasks for time‑critical system responses.
Provides battery‑buffered safe‑keep of process quantities, message/trace data, and OS exception diagnosis via the 256 KB SRAM (subrack battery or external 3.4 V battery).
Monitors system health using integrated self‑diagnostics, including a local 7‑segment display reporting both the configured CPU number (normal operation) and specific error codes.
Tests user programs using the built‑in serial service interface with DUST1 protocol (19.2 kbaud) and the “basis IBS” commissioning tool.
Q1: What exactly is the Siemens 6DD1600-0AK0?
A1: The 6DD1600-0AK0 is a PM6 RAPID 64‑bit CPU module for the SIMADYN D distributed control system, designed for computationally intensive open‑ and closed‑loop tasks with cycle times as short as 0.1 ms.
Q2: How many onboard binary inputs does the 6DD1600-0AK0 have?
A2: The 6DD1600-0AK0 provides 8 onboard binary inputs (24 V DC). A maximum of 4 can be used for interrupt tasks, while the rest function as standard inputs.
Q3: Is the 6DD1600-0AK0 still being manufactured by Siemens?
A3: No. Siemens officially discontinued the 6DD1600-0AK0 with lifecycle status PM500 effective October 1, 2017. No direct replacement product is offered.
Q4: What memory and cycle performance does the 6DD1600-0AK0 deliver?
A4: The 6DD1600-0AK0 includes 8 MB DRAM, 256 KB battery‑buffered SRAM, and achieves extremely fast cycle times of 0.1 ms, with a typical control loop configured in approx. 0.5 ms.
Q5: Can I still obtain a reliable 6DD1600-0AK0 for legacy system repair?
A5: Yes. Although Siemens discontinued the 6DD1600-0AK0, specialized industrial automation suppliers maintain new‑old‑stock, refurbished, and fully tested units, typically including a 1‑ to 2‑year warranty for legacy system maintenance.
