Hello there, I am trying to change the IP address of my 1769-L33 CompactLogix PLC. Unfortunately, the BOOTP software isn't detecting the device. I attempted to disable the firewall on my Windows 10 system, but it still didn't work. Is it possible that BOOTP doesn't recognize a device that already has an IP address assigned?
Changing the IP settings on a device can be easily done through RSLinx. If the device has already obtained an IP address, it will no longer send out BootP requests. To clear out the IP address, simply power cycle the device. If the device is configured with a static IP, you will need to establish communication on the correct subnet, which may require changing the IP address of your PC. Once communication is established, you can use RSLinx to modify the IP settings.
If you are unsure of the current IP address, an alternative method is to establish a connection via USB in RSLinx. This can be a helpful solution for troubleshooting network connectivity issues.
When setting up a device to communicate with another, utilize Wireshark to directly capture and analyze the outgoing packets, revealing its IP address. If unsuccessful, Zenmap can be used for a ping scan. However, without any knowledge of the subnet, the ping scan process may be lengthy. It is recommended to start with Wireshark for more efficient results.
Charley from Voos recommends using USB to connect through RSLinx if you are unsure of the current IP address. This alternative option is especially handy as Rockwell has incorporated USB connectivity into their modules, making the process even easier.
Yes, you're on the right track. BOOTP may not recognize devices that already have an assigned IP address. Besides, your problem could also stem from the BOOTP version, as some of them often struggle with Windows 10. In such cases, you can switch to DHCP/DNS instead of BOOTP if you can. Also, don't forget to check the compatibility of your device with the PLC hardware.
Yes, you're exactly on track! The BOOTP software won't detect a device that already has an IP address assigned. In your case, you can use the RSLogix 5000 software if you have it. It's a pretty efficient method for changing the IP address of the PLC. Alternatively, you may also use the RSLinx software. Remember, via these methods you should be able to make the adjustment without affecting your PLC's operation.
Yes, it's very possible that the BOOTP software is unable to detect a device which has an already assigned IP address. In my experience, BOOTP is most successful when interacting with devices that have a default or unassigned IP setting. It might be worthwhile to try and reset your PLC to its default IP settings if that's an option for you. Alternatively, if your PLC supports it, you could use a different tool like RSLinx or a web browser to change the IP. Remember to update your firewall settings post-process to prevent future network security issues.

Answer: Answer: There could be several reasons for this issue, such as network configuration problems, firewall settings, or compatibility issues between the PLC and the BOOTP software.
Answer: Answer: Apart from the firewall, ensure that there are no other security settings or network restrictions blocking the communication between the BOOTP software and the PLC. Also, check if the PLC is properly connected to the network.
Answer: Answer: BOOTP typically assigns IP addresses to devices that do not have one already. If the device already has a static IP address assigned, BOOTP may not be able to detect it. In such cases, you might need to manually change the IP address on the PLC itself.
Answer: Answer: Ensure that the network settings on both the PLC and the computer running the BOOTP software are correctly configured, including subnet masks, gateway addresses, and DHCP server settings. Additionally, check
