How to Assign a Specific IP Address with USB Connection to PLC or 1756-ENBT

Question:

Is it possible to assign a specific IP address of my choice using a USB connection?

Top Replies

Although the 1756-ENBT module lacks a USB port, you can connect to it through a CPU or a compatible card such as 1756-CN2R, 1756-DNB, or 1756-EN2T that does have a USB port. With the use of RSLinx Classic software, you have the flexibility to assign any desired IP address to the module.

Apologies for the confusion, I was actually referring to the 1756-en2t module. I have successfully assigned a new IP address to it. Can you provide guidance on how to establish communication between the 1756-en2t module and my plant network?

For assistance with basic networking, it is recommended to consult the specialists who set up and manage your network on-site. Trying to understand the specifics of your plant network and requirements can be overwhelming. If you are seeking information on TCP/IP and Ethernet networking basics, there are numerous online resources available that may not be specific to PLCs but can help you build a foundation to ask more targeted questions.

It's puzzling why some companies, like AB, don't seem to keep an eye on their competitors. I'm not criticizing anyone, but it appears that setting up AD's Click and BRX should be simpler. These PLCs can be easily identified on the network by their MAC or signature, allowing them to be easily configured when opening the software. It's clear that communication between PLC users and manufacturers is lacking, resulting in a lack of industry standards. After spending 6 hours on a simple fix yesterday, it's frustrating to see how difficult this process can be.

Nelson1603 inquired about the possibility of assigning a specific IP address using a USB connection. You can easily set the IP address by connecting through the PLC using USB. Simply access RSLinx, locate the device, right-click, and modify the properties as needed. BootP is recommended for a straightforward process, but if any complications arise, using USB as a backup option is highly effective.

While it might not be as straightforward as with an Ethernet connection, it is technically possible to assign a specific IP to a device via USB. It largely depends on the device and the operating system you're using. You will essentially turn your computer into a router that assigns the IP to the USB connected device. This can get a bit complex so it's a good idea to research on the specifics for your exact system to avoid any possible issues.

Yes, it is indeed possible to assign a specific IP address using a USB connection, but it will depend on the type of device you're connecting. For instance, when tethering a smartphone to a computer, the IP configuration is generally automatically handled. However, in the case of a USB to Ethernet adapter, you can manually configure a specific IP address through your operating system's network settings. Just bear in mind, the IP address you choose must be within the range of your network to maintain connectivity.

While you can set a static IP address on your device manually, using a USB connection to directly assign an IP address of your choice is a bit tricky since it depends on how the connection is set up and the operating systems involved. For example, if you're using USB tethering on a phone or a USB network adapter, you would typically configure the IP settings through the network settings in your OS, but keep in mind that the address must be within the subnet of the device to which it's connecting. So, while it's possible to dictate IP settings, you should ensure they don't conflict with existing addresses in your network to avoid connectivity issues!
