The CP 1623 is a PCI Express x1 communications processor that connects a PC or industrial PC to Industrial Ethernet. Its integrated two-port RJ45 switch supports 10, 100 and 1000 Mbit/s operation and works with HARDNET-IE S7 and S7-REDCONNECT environments.
The two RJ45 connectors form an integrated switch, allowing a PC station to join a line or local star segment without a separate two-port device.
2
External-power option
An external DC connection can maintain the switching function independently from the host PC. The wiring plan must preserve grounding and the permitted voltage range.
3
Host integration
The card uses a PCI Express x1 interface. Slot availability, BIOS behavior, operating system support and installed SIMATIC NET components should be checked before replacement.
4
Commissioning
Verify link speed, network addressing, S7 communication, redundancy behavior where used, event status and traffic continuity before returning the station to production.

BUYER FAQ
Questions Before Ordering 6GK1162-3AA00
Q1
Can 6GK1162-3AA00 be replaced by a standard Ethernet card?
Not as an assumed one-to-one exchange. The CP 1623 role includes the Siemens PC communication stack and HARDNET or REDCONNECT use. Validate the application architecture first.
Q2
Does 6GK1162-3AA00 need external 24 V DC?
It can receive power from the PCIe backplane. External 10.5 to 32 V DC is optional and can support switch operation independently of the host PC.
Q3
What should be checked before ordering 6GK1162-3AA00?
Confirm the full order number, host PC model, available PCIe slot, installed operating system, SIMATIC NET release, network topology and external-power wiring.
Q4
What network speed does 6GK1162-3AA00 support?
Its two RJ45 Industrial Ethernet ports support 10, 100 and 1000 Mbit/s.
Q5
Which acceptance checks suit 6GK1162-3AA00?
Check both links, negotiated speed, host recognition, S7 sessions, redundancy behavior when configured and uninterrupted traffic through the integrated switch.
