Siemens 6GK1162-3AA00 SIMATIC NET CP 1623 PCI Express Communication Processor
The Siemens 6GK1162-3AA00, also cataloged as the 6GK1162-3AA00 PCI Express Communication Processor, operates as a dedicated hardware component for high-performance Industrial Ethernet and PROFINET processing within PC-based SIMATIC NET automation architectures. The board offloads host CPU processing by handling protocol stack execution directly on its onboard ASIC, ensuring stable deterministic data transfer across industrial control networks. Equipped with an integrated two-port Ethernet switch and a PCIe x1 interface, the module establishes direct network connections for engineering workstations and control servers.

Profinet Deterministic Networks and Firmware Integrity
The Siemens 6GK1162-3AA00 offloads Industrial Ethernet frame processing entirely from the host PC processor, eliminating system-level jitter and latency variations during high-throughput cyclic operations. The board maintains deterministic transmission schedules across PROFINET IO lines by executing time-critical protocol stacks directly on internal microcontrollers. Furthermore, the onboard flash memory maintains full firmware flash compatibility, allowing field updates to preserve network synchronization across changing SIMATIC software versions without altering the physical hardware configuration.
Frequently Asked Questions
Q: How does host CPU offloading improve system performance on an engineering workstation?
A: The onboard communication processor executes all ISO, TCP/IP, and PROFINET protocol tasks independent of the host operating system, preventing host CPU load spikes from interrupting real-time network cycles.
Q: Can the integrated two-port switch operate if the host PC shuts down?
A: No, because the module derives its operational power directly from the PCIe bus (3.3 V and 12 V supply lines), a loss of power to the host PC de-energizes the internal switch and interrupts network pass-through traffic.
Q: What software drivers are required to enable redundant communication paths?
A: High-availability redundant communication requires installing the Siemens S7-REDCONNECT software package alongside the SIMATIC NET driver stack to manage automated line switching.
Field Installation Guidelines
Before installing the board, power down the host IPC or workstation, disconnect the main power cable, and apply proper ESD grounding measures. Insert the card firmly into an available PCI Express x1 slot on the motherboard and secure the mounting bracket using the cabinet retention screw to ensure ground continuity across the chassis.
Route industrial-grade shielded CAT5e or CAT6 Ethernet cables away from high-voltage motor power leads and variable frequency drive outputs to prevent electromagnetic interference. Connect the RJ45 connectors to the dual onboard ports, ensuring that the connector latching mechanisms click fully into place. Verify that the cable shield connects directly to the metal housing of the RJ45 port to maintain low-impedance ground bonding back to the main enclosure earth bus.
