Hello, I am attempting to establish a connection with injection machines. Unfortunately, I am unable to set their IP address as it is restricted and shows as 127.0.0.0. This limitation is causing me a lot of difficulty in establishing a connection. Even when I connect an USB to my computer and the injection machine, I am unable to see any activity on Wireshark. However, when I use an Ethernet cable, I notice a large amount of UDP protocol traffic but no OPC UA. I have configured protocols for OPC UA ports 4840, 4841, 4842, and 48030 on Wireshark. I have not yet attempted to connect using RS232. The injection machines I am trying to connect to use Keba Plc CP053/Y. My goal is to gather data such as cycle times, pressure, temperature, and other values from these machines. Once I am able to establish a connection, I would like to know how to retrieve this data for various Injection Machines (Arburg, Haitian, Fanuc, etc.).
The IP address 127.0.0.0 is not considered a valid address and is designated for the host loopback function.
According to jstolaruk, the IP address 127.0.0.0 is not a valid one as it is reserved for loopback. I attempted to use a Bootp-DHCP tool with USB and Ethernet cables but was unsuccessful. I will try using rs232 once I have access to it. Unfortunately, it seems impossible to retrieve data from the PLC without configuring the IP address. Is there a way to change the IP address that is currently blocked on the machine's HMI?
I would like to emphasize that the IT department should avoid attempting to establish connections with PLCs in order to ensure operational safety and prevent potential system disruptions.
Hey there! Given the specifics of your issue, it seems like you have a networking problem. You mentioned seeing a lot of UDP traffic with an Ethernet connection but not OPC UA, which suggests that your OPC server might not be properly configured. Please review the server settings to make sure it's actually listening on the ports you mentioned. About the IP address issue, 127.0.0.0 is the loopback address, used mostly for testing. Can you manually set the machine's IP or is it issued via DHCP? If you can set it manually, I'd recommend doing that and ensuring the correct subnet and gateway are applied. Regarding the data collection, you will need the KEBA OPC UA server Accessory Package and KEBA i-Client OPC UA, which provides interfaces for monitoring and operating the injection machine once you have established the proper connection. It might help to consult with an IT support or KEBA support to assist you in breaking through these roadblocks!
It sounds like you're dealing with a fair bit of network traffic complexity here. One potential fix for the 127.0.0.1 issue could be to try and assign a static IP to your injection machines if that's at all possible. Regarding the OPC-UA issue, have you set the firewall to allow incoming connections on those specific ports you mentioned? For data gathering from different machines, once a successful connection has been made, specific APIs would be helpful to work with each machine's unique protocol. Unfortunately, without knowing the specific machine models and their communication capabilities, it's hard to give precise advice. But you might consider contacting the manufacturer or support for each of these machines for more tailored information about data retrieval.
It sounds like you're dealing with quite a complex connectivity issue. It seems to me that you’re on the right track with attempting a connection using an ethernet cable. IP addresses that start with 127 are loopback addresses only and always pertain to your own computer, not other machines on the network. Given that you're seeing a lot of UDP traffic and no OPC UA, I'd double-check your firewall rules and port configurations to ensure nothing is being blocked. As for the machine data you're trying to unearth, once the connection is established, you would likely need to interface with the machines' respective APIs or use manufacturer-specific software to extract the desired data. Consider connecting via RS232, but remember that each machine could have a different protocol for transmitting data, so reference manuals for these specific models could be invaluable. Hope this helps and all the best for your endeavors!
It sounds like you're facing quite a challenge! Given that the IP address is showing as 127.0.0.0, it seems like the machines might be set up in a way that they default to a local host or that your computer isn't correctly recognizing the machine's network configuration. It might be worth checking if there's any specific configuration tool provided by Keba that could help you set the correct IP. Regarding the UDP traffic you're seeing, perhaps it’s worth monitoring the ports closely to see if you can catch any relevant packets that could give you insight into communication formats. As for RS232, it's definitely worth trying out as sometimes legacy systems can work better that way, especially if network settings are tight. When you do establish a connection, a library like OPC UA .NET or Java can help in retrieving the data from different machines smoothly. Good luck!
It sounds like you're dealing with quite a challenge! The 127.0.0.0 IP indicates a local loopback issue, which usually means the machines might not be configured for network access at all. First, I'd suggest checking the machine's network settings or documentation to see if there's a way to enable the proper IP addressing—sometimes there are settings hidden in a configuration menu. Regarding the communication protocols, since you're seeing UDP traffic, it could be useful to explore if that's how the machines are set up to communicate rather than through OPC UA. You may want to consult the manufacturer’s protocol documentation as well—Keba or the specific injection machines might have unique requirements for connecting. And don't overlook trying RS232; it might be an easier path if network options remain problematic. Good luck getting that data you need!
It sounds like you're dealing with quite a challenge! Since you're getting so much UDP traffic but no sign of OPC UA, it might be worth checking if the machines have specific settings or protocols that need to be enabled first. Sometimes, industrial devices require configuration adjustments on the device itself to allow external connections, especially for OPC UA. Have you had a look at the user manual or any configuration interface? Additionally, since Keba PLCs might support multiple communication protocols, exploring RS232 could open up new options. Have you considered reaching out to Keba support or checking forums specific to your injection machine models? They might have some insights or even specific example code for data retrieval. Good luck!

Answer: Answer: The restriction on setting the IP address could be due to various reasons, such as network configuration issues or security settings. You may need to consult the machine's manual or contact the manufacturer for guidance on how to properly configure the IP address.
Answer: Answer: If you are not seeing any activity on Wireshark when using a USB connection, ensure that the drivers are installed correctly and that the connection settings are properly configured. When using an Ethernet cable, the presence of UDP protocol traffic indicates communication but the absence of OPC UA traffic may require further investigation into the network setup or machine compatibility.
Answer: Answer: Connecting via RS232 may provide an alternative communication method if USB or Ethernet connections are not successful. Ensure that the correct cables and settings are used for RS232 communication. It is important to explore multiple connection options to troubleshoot and establish a reliable connection with the injection machines.
