  • Page 17: Configure The Adapter For Your Ethernet/Ip Network

    Before you can use your 1794-AENTR or 1794-AENTRXT adapter, you must configure its IP address, and optionally, its subnet mask and gateway address. You can use the Rockwell Automation BOOTP/DHCP utility to perform the configuration. You can also use generic BOOTP software or, within some limitations, a DHCP server.

  • Page 18: Gateway Address

    The gateway has two IP addresses (128.1.0.2 and 128.2.0.3). The first must be used by hosts on Network 1 and the second must be used by hosts on Network 2. To be usable, a host’s gateway must be addressed using a net ID matching its own. Rockwell Automation Publication 1794-UM066C-EN-E - April 2023...

  • Page 19: Subnet Mask

    The FLEX I/O adapters support the following additional methods to change the IP address: IP Address • BOOTP/DHCP tool • RSLinx Classic software For more information on how to use these methods, see EtherNet/IP Network Devices User Manual, publication ENET-UM006.
