Siemens 6DD1660-0AK0 CS41 Communication Module

  • Used in the SIMADYN D System for Data Transfer Between
  • (2) 16-Bit Processors V25 (70320)
  • 8 Mhz System Clock


The Siemens 6DD1660-0AK0 CS41 Communication Module is used in the SIMADYN D system for fast data transfer between SIMADYN D and digital AC and DC converters, e.g. SIMOREG K and SIMOVERT or ET 100.

The module is addressed by SIMADYN D (processor module PM12/16) via the local bus (L bus) of the system using a programmable address decoder (PAD).

It has two 16-bit processors V25 (70320) with external de-multiplexed 20-bit address and 8-bit data bus. The system clock is 8 Mhz.

Data transfer to the L bus is realized using 2 dual port RAMs (DP-RAM), each with 2 kbyte memory. The read and write cycles to the L bus are organized wordwise, and the internal accesses from the V25 processor to the dual port RAMs, bytewise.

Access control on both sides is realized using a hardware arbitration logic.

Each of the two processor has a 64-kbyte EPROM as program memory and 32 kbyte buffered SRAM as working memory.

The processors have 2, independent serial interfaces, which are fed to the 15-pin sub-D plug connectors X5-X8 via the corresponding transmit and receiver module, and which establish the connection to the digital AC and DC drive converters from the SIMOREG K and SIMOVERT series, or to the distributed ET100 I/Os.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
