6GK1161-6AA02 is a Siemens SIMATIC NET CP 1616 communications processor in 32-bit PCI format. It connects PC-based automation systems to PROFINET IO.
The card uses an ERTEC 400 ASIC and integrates a four-port 100 Mbit/s real-time Ethernet switch with RJ45 connections. It can operate as a PROFINET IO controller or device.
The official data sheet specifies a 5 V PCI supply, optional 6 to 9 V external supply, typical power loss of 4 W and an operating temperature range of 5 to 70 °C.
It is used for real-time PROFINET IO communication between PC-based controllers, devices and industrial Ethernet networks.
It is compatible with PC stations providing a 32-bit 33/66 MHz PCI slot and software supporting the CP 1616 PROFINET IO controller or device functions.

Important Notice: Accessories, software, cables, licenses and calibration records are supplied only when specifically stated in the quotation or stock description.
The four 100 Mbit/s RJ45 ports support PROFINET IO, IRT and Media Redundancy Protocol. Configure controller or device operation according to the PC station project.
It is used for real-time PROFINET IO communication between PC-based controllers, devices and industrial Ethernet networks.
It is compatible with PC stations providing a 32-bit 33/66 MHz PCI slot and software supporting the CP 1616 PROFINET IO controller or device functions.
Use a compatible 32-bit PCI slot and observe the 5 V backplane supply, optional 6 to 9 V external supply and 5 to 70 °C operating range.
Verify PCI voltage/keying, NCM PC or development-kit configuration, network topology, external supply requirements and the four RJ45 connections.
The CP 1616 is a 32-bit PCI PROFINET IO processor using an ERTEC 400 and an integrated four-port 100 Mbit/s real-time switch. It supports controller/device operation, IRT, MRP and PC-based PROFINET communication within its specified power and temperature limits.
Before commissioning, verify the complete order number 6GK1161-6AA02, physical interface, engineering software or firmware requirements, and the configuration of the existing Siemens system.
Siemens lists 6GK1161-6AA02 as PM400, with product phase-out announced from 01.10.2025. Moore Automated supplies quality Siemens communication processors and spare modules to support PC-based PROFINET systems and minimize network downtime.
Moore Automated supports customers with order-code verification, condition confirmation and sourcing of Siemens replacement modules or compatible spare parts for this exact configuration.
For discontinued products, the documented successor or migration path should be checked against the installed hardware, software and field wiring before replacement. This supply and verification approach helps shorten maintenance decisions and reduce unplanned downtime.
