Features:
- Stateful industrial firewall with NAT/NAPT
- Two RJ45-or-SFP combo network connections
- VLAN, static routing, logging, and SINEMA RC client functions
Siemens 6GK5622-2GS00-2AC2 filters and routes traffic between two industrial network zones.
Copper or optical media can be selected independently of the firewall rules, so the physical connection and security policy remain separate decisions.
Web, CLI, SNMP, and event logs expose security and interface conditions without sending those management functions through the digital alarm contacts.
The Siemens 6GK5622-2GS00-2AC2 SCALANCE SC622-2C Industrial Security Appliance may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How traffic crosses the security boundary
- Stateful inspection: 6GK5622-2GS00-2AC2 evaluates connection state before traffic passes between zones.
- Address translation: NAT changes network addresses, while NAPT can also map multiple connections through translated ports.
- Rule enforcement: Packet filters define which source, destination, and service combinations may cross the appliance.
- PROFIsafe separation: The appliance provides the documented network-separation function for PROFIsafe communication designs.
Choosing copper or optical media
- RJ45 mode: A combo connection accepts 10/100/1000 Mbit/s copper Ethernet through its RJ45 interface.
- SFP mode: The optical alternative uses a 1000 Mbit/s SFP transceiver in place of the paired copper path.
- Port pairing: Only one media interface of each combo pair carries traffic at a time.
- Status separation: The signaling contact and digital I/O report or control cabinet signals independently of the selected network medium.
Moving traffic between logical networks
- Static routes: Configured IPv4 or IPv6 routes tell 6GK5622-2GS00-2AC2 which gateway or interface reaches each network.
- Dynamic routing: OSPFv2 and OSPFv3 exchange route information for IPv4 and IPv6 projects.
- VLAN separation: Port-based VLANs divide logical traffic before firewall and routing policies are applied.
- Gateway redundancy: VRRP allows a configured gateway address to be maintained by a redundant routing arrangement.
Evidence for security and interface events
- Packet-filter log: Denied or matched traffic rules create events that identify the security decision.
- Audit log: Configuration and access changes are recorded separately from packet handling.
- System log: Device-level events expose operating and service conditions of 6GK5622-2GS00-2AC2.
- Port diagnostics: Interface state and traffic statistics distinguish cabling faults from firewall-rule blocks.
