- SIMADYN D CS21 communication module for parallel rack coupling
- Dedicated slave-side role in the configured inter-rack connection
- Order-specific Siemens product requiring exact project compatibility
6DD1660-0AE0 is a Siemens CS21 communication module designed for the SIMADYN D control platform.
It forms the slave side of a parallel rack-coupling path so configured CPUs and interfaces can exchange data between SIMADYN D subracks.
Before installation or replacement, verify the complete order number, rack and slot, master/slave pairing, connector arrangement, project routing, and installed-system documentation.
Availability, condition, price, and shipping time for 6DD1660-0AE0 are confirmed during quotation.

- The CS21 occupies the slave side of the SIMADYN D parallel rack connection.
- The coupled system requires the project-defined master-side interface in the partner rack.
- Master/slave assignment and interface routing are established in the SIMADYN D project.
- Rack, slot, CPU association, and interface names must match the saved control project.
- Configured data paths route information between CPUs and communication interfaces across subracks.
- Connector and cable identity must be preserved when replacing the slave-side module.
- Siemens lists Germany as the country of origin for 6DD1660-0AE0.
- SiePortal states that the product is not RoHS-compliant.
- Siemens classifies the article as a customer-/order-specific engineered product.
- Slave-side parallel coupling between two SIMADYN D subracks
