Features:
- Accepts up to three SS4, SS5, or SS52 communication modules in a single slot.
- Combines Dedicated memory for each module to exchange data with the CPU via L‑bus.
- Two LEDs per compartment, test sockets, and full L‑bus interface for synchronization and interrupts.
The 6DD1662-0AB0 features three independent plug‑in receptacles (X01, X02, X03), each designed to host an SS4, SS5, or SS52 communication module. This allows a single CS7 carrier to support up to three different serial communication channels simultaneously. For example, one receptacle could run PROFIBUS via an SS52, another handle USS protocol via an SS5, and a third manage DUST – all without consuming additional subrack slots. This dense integration saves valuable backplane space and reduces system cost.
Each communication module plugged into the 6DD1662-0AB0 gets its own dedicated 16 Kbytes of dual‑port RAM. This memory acts as a shared buffer between the communication module and the CPU, allowing high‑speed data transfer via the L‑bus without burdening the CPU with bit‑level serial handling. The CPU can read from or write to this RAM at any time, while the communication module independently updates its contents. This parallel operation eliminates data collisions and reduces latency.
The 6DD1662-0AB0 includes two diagnostic LEDs per compartment (e.g., H10/H11 for receptacle X01). These LEDs give immediate visual feedback on the status of each plugged SS4/SS5/SS52 module – though the exact meaning depends on the module itself. Additionally, the CS7 provides a full L‑bus connection, enabling transfer of the L‑bus basic sampling time for synchronization (even if not used by SS4/SS5/SS52) and the ability to generate L‑bus interrupts.
The 6DD1662-0AB0 Siemens Communication Module may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).
