Hello, we are currently working with Rockwell FlexIO ethernet modules (5094-AEN2TR) and are attempting to assign a specific static IP address. The module allows for adjustment of the fourth octet using rotary dials, making it easy to set an IP like 192.168.1.xxx, where xxx corresponds to the dial setting. However, we require an IP address within a different range, such as 172.xxx.xxx.xxx, and are exploring alternative methods to configure the IP. We have experimented with the BOOTP method, but encountered difficulties. By setting the rotary dials to 999 (BOOTP mode), connecting a computer to the ethernet module via an ethernet cable, running the BOOTP protocol, and power cycling the module while periodically restarting BOOTP for communication, we managed to display the MAC address. However, attempts to write the IP command to the module resulted in the LED blinking and the command timing out, preventing the IP address from being set successfully. Is there a simpler approach to assigning a static IP to these modules? We attempted configuring the IP online with the address 192.168.1.xxx, but the rotary dial settings took priority and the IP was not retained. Additionally, the absence of a USB port limits our options. Thank you.
Are you sure your computer's network interface card (NIC) is configured for the desired subnet, such as 172.xxx.xx.xx? Also, make sure you are using the correct version of the EtherNet/IP commissioning tool. The 5069-AENTR installation instructions recommend using version 3.02 or later. In the past, I have encountered issues with the BOOTP/DHCP tool failing to disable BOOTP/DHCP, but I have always been able to assign addresses successfully as long as there are no conflicts with firewalls or VPNs. Make sure there are no routers, access points, or other devices on the network that may be assigning IP addresses before the utility can.
Once you have connected to the internet using the IP address 192.168.1.xxx and configured the necessary settings, adjust the dials to a number above 254, as well as different values for 999 and 888.

Ken Roach inquired about the settings for the computer NIC for a specific subnet (172.xxx.xx.xx) and which version of the EtherNet/IP commissioning tool is being utilized. According to the 5069-AENTR installation instructions, a version of 3.02 or later is recommended. Troubles have been encountered in the past with the BOOTP/DHCP tool failing to disable BOOTP/DCHP, but address assignment has been successful when firewall or VPN issues are not present. It is important to ensure that no other devices on the network are providing IP addresses before the utility can respond. The issue with Bootp disabling bootp after IP assignment occurs when the controller takes ownership immediately in an IO configuration, making it impossible to disable bootp or linx. To resolve this, the module must be opened in the project online, the connection inhibited, and the IP set to static in the internet properties of the module in Studio. A fail-proof procedure is outlined as follows: Bootp until IP assignment appears, go online with the PLC, open properties, inhibit connections, set internet connections to static, remove inhibition, and complete. If a controller is not yet online with the module in its IO tree, simply disable bootp and set to static by right-clicking on the module in rslinx, selecting module configuration, internet protocol, and setting to static. It is crucial to match the IP octets of the device being set with the laptop or PC IP with bootp enabled.
Having difficulty configuring IP addresses? One solution is to temporarily set the IP address to 192.168.1.1 by dialing 001. Ensure your laptop is within the same range, then access the module via a web browser. From there, customize the IP address to your desired one and disable BootP. While a bit time-consuming, this method has proven effective in resolving IP address issues. Cheers, Mark.
Hi there, it seems like you've gone through some extensive troubleshooting already. For the Rockwell FlexIO modules, BOOTP is indeed the primary method to assign a unique IP outside the rotary dial range. I would recommend double-checking the BOOTP server software for any overlooked settings. Sometimes, you need to "disable BOOTP" for the module’s MAC address in the server software after setting the desired IP, which makes the module remember the IP upon restarts. Additionally, ensure your firewall isn't blocking the BOOTP commands. Lastly, depending upon the PLC and firmware version, you might be able to use RSLogix 5000/Studio 5000's "Module Configuration" set up for IP configuration. Please keep us informed about your progress!
It seems like you've tried a pretty comprehensive range of options here. One method you might not have considered is using Rockwell's RSLinx Classic software. This can allow you to configure the device IP even when you're not able to set it directly on the device. You should be able to use the "RSWho" browsing utility to find your module on the network (given its MAC address), then use the right-click menu to set the module's IP. This approach has worked for me with similar Rockwell Ethernet modules in the past. I hope this helps!

Answer: The module's rotary dials allow adjustment of the fourth octet for IPs within the 192.168.1.xxx range, making it challenging to set IPs in different ranges like 172.xxx.xxx.xxx.
Answer: One alternative method is to try using the BOOTP protocol, but users may encounter difficulties in writing the IP command to the module and setting the desired IP address successfully.
Answer: To attempt setting a static IP using BOOTP, users can set the rotary dials to 999 (BOOTP mode), connect a computer to the module, run the BOOTP protocol, and power cycle the module while ensuring proper communication. However, issues such as LED blinking and command timing out may prevent successful IP configuration.
