When to keep DHCP on

Turn DHCP ON when the device is connected to a network with a DHCP server (most typical office/home networks with a router). The device will automatically obtain the following:

  • IP address

  • Subnet mask

  • Gateway

  • DNS servers

Use this setting when:

  • You don't need a fixed IP address for the device

  • A router/DHCP server is present on the network

  • You want zero-configuration networking

  • The device may move between networks

When DHCP is ON, the IP fields are shown as read-only (greyed out) and display the currently assigned values.

When to turn DHCP off

Turn DHCP OFF when you need to assign a fixed/static IP address to the device in cases when:

  • The device must always be reachable at the same IP (e.g., for SCADA, BMS, or Modbus TCP integration)

  • No DHCP server is available on the network

  • Network policy requires static addressing

  • You need predictable firewall or routing rules
