More Information

Overview Manuals Mobile Routing Firewall and VPN Cabinet Signals Configuration Access

Features:

  • Two local Ethernet ports feed one cellular routing path.
  • The exact -2FA2 ordering number is the China-approved M874-3 variant.
  • Firewall and VPN rules govern traffic crossing the mobile link.
The local switch keeps two automation devices on the same Ethernet side of the router.

Mobile traffic leaves through the SMA-connected HSPA+/UMTS interface after the configured routing and address translation.

Isolated input and relay output signals can connect cabinet status logic without sharing the router electronics.

The Siemens 6GK5874-3AA00-2FA2 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).

Moving automation traffic through the 3G path

  • Local side: Two RJ45 ports connect Ethernet automation devices to the internal switch.
  • Radio side: The SMA antenna connection serves the HSPA+/UMTS and GSM path.
  • Address handling: NAT and port-forwarding rules decide how local addresses and services appear across the mobile network.
  • Country variant: The -2FA2 ordering number identifies the documented China approval of M874-3.

Controlling access across an untrusted mobile network

  • State inspection: The firewall checks layer-three and layer-four connection state before forwarding traffic.
  • Encrypted paths: IPsec tunnels and OpenVPN client mode protect selected remote connections.
  • Connection scale: The documented VPN configuration allows up to twenty connections.
  • Remote service: SINEMA Remote Connect client functions can place the router in a managed remote-access path.

Linking network operation with cabinet status wiring

  • Digital input: One isolated 24 V DC input receives a binary cabinet condition.
  • Relay output: One isolated output can switch an external status circuit up to its documented load.
  • Power path: A five-pin terminal accepts the router's 12 to 24 V DC supply.
  • Cable limits: Supply and digital-signal wiring follow the documented maximum cable lengths.

Separating browser and command-line administration

  • Web interface: HTTP or HTTPS WBM presents the router settings in a browser.
  • Command line: Telnet or SSH provides CLI access for text-based administration.
  • Monitoring: LED states, event logging and SNMP expose operating and diagnostic information.
  • Time services: NTP, secure NTP, SIMATIC time and SNTP options align event timestamps.
Description
Siemens 6GK5874-3AA00-2FA2 is the China-approved SCALANCE M874-3 industrial 3G router. It connects Ethernet automation devices to an HSPA+/UMTS mobile network while routing traffic between the local switch and the cellular interface.

Two RJ45 ports on 6GK5874-3AA00-2FA2 form the local Industrial Ethernet side, while the SMA antenna socket serves the mobile-radio path. NAT translates the connected device addresses before selected traffic leaves through the cellular connection.

Security processing in 6GK5874-3AA00-2FA2 combines a stateful firewall with IPsec tunnels and OpenVPN client operation. Firewall rules, port forwarding and VPN parameters determine which local services can cross the mobile link.

A separate digital input and isolated relay output let 6GK5874-3AA00-2FA2 exchange simple status signals with the surrounding cabinet. The 12 to 24 V DC supply powers the router, while WBM or CLI provides its configuration and diagnostics.

The 6GK5874-3AA00-2FA2 suffix identifies the China-approved M874-3 variant, so its permitted radio use and antenna arrangement must match the destination country.
Can Siemens 6GK5874-3AA00-2FA2 connect two Ethernet devices without another switch?
Yes. Siemens 6GK5874-3AA00-2FA2 has two 10/100BASE-T RJ45 ports on its local switch, allowing two Ethernet devices to share the routed mobile path.
How is remote traffic restricted on 6GK5874-3AA00-2FA2?
On 6GK5874-3AA00-2FA2, NAT, port-forwarding rules and the stateful firewall determine which local services cross the cellular interface; VPN policies can encrypt selected connections.
What should be checked when the mobile link of Siemens 6GK5874-3AA00-2FA2 is weak?
For Siemens 6GK5874-3AA00-2FA2, verify the SMA antenna connection, approved antenna type, network coverage and configured radio band before changing routing or firewall settings.
Which supply and I/O wiring belongs to 6GK5874-3AA00-2FA2?
The 6GK5874-3AA00-2FA2 uses a 12 to 24 V DC supply, one isolated 24 V DC input and one isolated relay output; keep each circuit within its documented terminal and cable limits.
