A PC communications processor for deterministic SIMATIC NET connectivity, S7 communication and engineered high-availability links.
The Siemens 6GK1161-3AA00 is the original SIMATIC NET CP 1613 (A1) communications processor. It installs in a PCI slot of a programming device, industrial PC or workstation and connects the host to Industrial Ethernet. The module processes protocol layers on its own hardware and exchanges data with host memory through dual-port RAM, reducing communication load on the PC.

| Application | Engineering relevance |
|---|---|
| SIMATIC PC station networking | Connects a PCI-based PC station to Industrial Ethernet for configured SIMATIC NET communication. |
| S7-400H communication | Supports fault-tolerant S7 connections when the PC station is engineered with STEP 7 and licensed S7-REDCONNECT software. |
| OPC data access | Can serve an engineered SIMATIC NET OPC station for communication with S7 systems. |
| Industrial Ethernet commissioning | Provides CP-based PC connectivity for engineering, diagnostics and network commissioning workflows. |
Siemens documentation distinguishes CP 1613 A1 6GK1161-3AA00 from CP 1613 A2 6GK1161-3AA01. Because the available official record for this complete A1 article does not state a current PLM phrase, no lifecycle label is assigned here. Procurement should be based on the exact article number, released software environment and verified hardware condition.
No. 6GK1161-3AA00 identifies CP 1613 A1. CP 1613 A2 is article 6GK1161-3AA01 and must not be substituted without an engineering review.
The documented interfaces are an RJ45 socket for twisted pair and a 15-pin Sub-D socket for ITP or AUI connection.
Yes, in a correctly engineered PC station with STEP 7/NCM PC and the required SIMATIC NET S7-REDCONNECT license.
Confirm the complete order number, PCI edge, connector condition, board revision, traceability label and compatibility with the released software environment.
