The Siemens 6DD1606-2AC0 serves as a high-performance CPU for SIMADYN D platforms. This module executes complex drive and motion control algorithms efficiently. You will find this processor in rolling mills, wind turbines, and test stands. It handles real-time calculations with microsecond response times.

Manufacturer: Siemens
Series: SIMADYN D
Category: Processor Module (32-bit CPU)

Physical Dimensions and Weight

The Siemens 6DD1606-2AC0 measures 12.5 inches in length. Its width reaches 1.6 inches for single-slot occupancy. The board thickness sits at 6.0 inches including components. This standard form factor fits into any SIMADYN D rack. The total weight comes to approximately 0.65 kilograms.

Technical Specifications and Processing Power

This processor module uses a 32-bit RISC microcontroller architecture. It operates at a clock speed of 40 MHz. The module stores user programs in 2MB of battery-backed RAM. Additionally, it holds 1MB of flash memory for firmware storage. The typical cycle time reaches 200 microseconds for 1,000 instructions.

Energy Storage and Data Retention

The Siemens 6DD1606-2AC0 includes a replaceable lithium battery for RAM backup. This battery provides 12 months of data retention without external power. A supercapacitor array adds 168 hours of temporary backup during battery changes. Therefore, you can replace the battery without losing critical parameters. The module also stores boot code in non-volatile flash memory.

Interface and Connectivity

This processor module features multiple communication interfaces for flexibility. A built-in Ethernet port supports 10/100 Mbps network connections. Two RS-232 serial ports connect to programming terminals and HMIs. The front panel includes an 8-position DIP switch for configuration. Six LED indicators show RUN, STOP, and diagnostic status clearly. You can access all ports without removing the module from the rack.

Component Layout and Memory Architecture

The Siemens 6DD1606-2AC0 contains 210 discrete components on an eight-layer PCB. Key parts include the main CPU chip and 32 memory ICs. The memory architecture divides into four distinct banks. Program blocks occupy 1MB of the address space. Data blocks use another 512KB, and system variables use 256KB. The remaining 256KB serves communication buffers and diagnostics.

Integration and Compatibility

Use the Siemens 6DD1606-2AC0 with any SIMADYN D I/O rack. It works alongside 6DD1607-0AC2 or 6DD1608-0AC2 I/O modules. This processor supports all standard SIMADYN D configuration software.
