1:1 NAT in Machine Automation: Integrating Identical OEM Machines Without IP Conflicts

How machine builders and system integrators connect multiple identical machines with identical internal IP addresses to a single plant network using 1:1 Network Address Translation.

  • Machine OEMs standardize internal machine code with fixed IP addresses (e.g., PLC is always 192.168.1.10).
  • Connecting identical machines directly to a factory network creates catastrophic IP conflicts.
  • 1:1 NAT maps an internal IP address to a unique external plant IP without changing a single line of PLC or HMI software.
