More Information

Overview Manuals Mobile Link Routing VPN/Firewall Management

Features:

  • GSM, UMTS, and HSPA+ transport carries IP traffic from Ethernet automation devices.
  • IPsec VPN, stateful firewall, and NAT functions process traffic before it reaches the mobile network.
  • A two-port local switch, SMA antenna socket, digital input, and digital output share one compact router.
Ethernet devices connect to the two internal ports of Siemens 6GK5874-3AA00-2AA2 before traffic is routed to the cellular interface.

Security rules in 6GK5874-3AA00-2AA2 determine which addresses, services, and VPN flows may cross between the local and mobile networks.

Management and diagnostics for 6GK5874-3AA00-2AA2 use its web interface, HTTPS, SNMPv1, email traps, and time synchronization.

The Siemens 6GK5874-3AA00-2AA2 SCALANCE M874-3 3G Router may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Cellular Network Path

  • Radio families: The WAN path accepts GSM and UMTS networks.
  • Packet services: GPRS, eGPRS, and HSPA+ provide the documented mobile data services.
  • Antenna connection: The external radio path uses a 50-ohm SMA socket.
  • National approval: The installed radio configuration must follow approvals for the country of operation.

Address Translation and Forwarding

  • Masquerading: NAT can present internal addresses through the routed external connection.
  • Fixed mapping: 1:1 NAT maps a selected internal and external address pair.
  • Service exposure: Port forwarding directs defined incoming services to an internal endpoint.
  • Traversal: NAT traversal supports applicable protected communication across translated paths.

Protected Traffic Processing

  • Firewall state: Stateful inspection evaluates packets against the active connection state.
  • Packet filter: Rules can permit or reject traffic by the configured packet criteria.
  • VPN mode: IPsec is available in both tunnel and transport modes.
  • Access control: Password protection and HTTPS restrict management access to the router.

Configuration and Diagnostic Channels

  • Browser setup: Web-based management provides the configuration interface.
  • SNMP check: SNMPv1 exposes supported status information to a management station.
  • Email event: Configured traps can be sent by email for diagnostic notification.
  • Clock service: NTP aligns the router clock used by time-dependent records and services.
Description
Siemens 6GK5874-3AA00-2AA2 is a SCALANCE M874-3 industrial cellular router that transfers IP traffic from Ethernet-based automation devices through GSM, UMTS, or HSPA+ mobile radio. Its routing functions join the two-port internal Ethernet switch to the external mobile network path.

Security processing in 6GK5874-3AA00-2AA2 can apply a stateful inspection firewall, packet filters, password protection, and IPsec VPN tunnel or transport mode before traffic crosses the cellular connection. NAT, 1:1 NAT, port forwarding, NAT traversal, and DNS cache functions control how internal addresses appear outside the local network.

At the hardware edge, 6GK5874-3AA00-2AA2 uses two RJ45 ports for the internal network and a 50-ohm SMA socket for the mobile antenna. One digital input and one digital output give the router separate field-status and control signal paths alongside the communication ports.

Web-based management configures 6GK5874-3AA00-2AA2, while HTTPS, SNMPv1, email traps, and NTP support administration, diagnostics, and time alignment. The 24 V DC terminal supply accepts 10.8 to 28.8 V DC for DIN-rail, wall, S7-300 rail, or S7-1500 rail mounting.

Technical notes
Cellular routing in Siemens 6GK5874-3AA00-2AA2 combines GSM/UMTS/HSPA+, a two-port Ethernet switch, IPsec VPN, stateful firewall, NAT, and field I/O.
