Hello! We are currently in the process of planning a cut-over for a MCC Advantage Starter DeviceNet Module, specifically focusing on segregating some IOs on a new PLC. While I am fairly certain that the modules in question are Cutler Hammer WPONIDNA modules, they were likely installed around 20 years ago. Unfortunately, the MCC is already powered and the drawings are not up to date, making it difficult to confirm at this time. I was able to find a picture of the module, but the manual has long been replaced by Eaton C441 DeviceNet Modules. Based on the pictures I have seen, it appears that you cannot set the Node address using switches. Do I need a specific software to configure the addresses? If so, what software should I use? Additionally, I am curious about the required end of line resistance for closing the daisy chain. Any insights on this would be greatly appreciated. Thank you.
While I cannot provide information specifically on these modules, it is important to note that the DeviceNet specification mandates the use of a 121Ω termination resistor at both ends of the trunk cable.
Thank you. Understandable.
Inquiring about setting Node addresses with switches based on images seen, dalporto questioned the need for software to configure addresses and what software would be necessary. Reflecting on past experience with CH DeviceNet systems in the '90s, they recalled using a software package and PCM-CIA card to directly connect to the DN network for configuration, as switches couldn't be used for this purpose. To potentially assist with this query, a document from Eaton might provide helpful information.

When the WPONIDNA was unpacked at Node 63, it followed the typical device setup process. However, the DeviceNet Object, which includes MAC ID and Data Rate, can only be adjusted through the network using configuration tools such as C-H Net View or RSNetworx for DeviceNet's node commissioning tool. Typically, C-H and A-B networked MCC's were configured by connecting and verifying each device one by one, setting the DNet Object, and power cycling to confirm successful configuration.
I want to express my gratitude to everyone involved in this project. I am eagerly awaiting the customer to send me the .dnt configuration file for RSNetwork so I can learn more about the setup and appearance, as this is unfamiliar territory for me. I initially believed that every starter required a Node number similar to IO Flex drops, but connecting them sequentially now seems like a logical approach.
Yes, you're correct. For these older Cutler Hammer modules, you would need to use a programming software to set the Node address and other parameters. Eaton's RSNetWorx for DeviceNet software should be able to get the job done for you. For the end of line resistance, typically a terminating resistor of 120 ohms is used to avoid reflected waves in the network. make sure you install them at both ends of the trunk line. Do consult your hardware manual for any specific requirements related to your device.
Hi there! It sounds like you've got quite a task on your hands. In the case of the older WPONIDNA modules, they indeed don't have settable switches for the node address and you do need the specific software, usually RSNetworx for DeviceNet or something similar, to configure addresses. As for the end of line resistance, DeviceNet standards typically call for 120 ohm resistors at both ends of the network to match the characteristic impedance. Be sure to check the specific installation guide of your module for any unique requirements, but this should generally hold true. Best of luck with your project!
For the WPONIDNA modules, you will indeed need to utilize software for configuring the nodes. Eaton's NetView software is generally recommended. It allows you to assign node addresses and manage other functions. When it comes to end of line resistance, typically, a 120 Ohm resistor is used to terminate both ends of the DeviceNet cabling. Make sure to comply with all the safety guidelines while dealing with the powered MCC, and I'd advise getting the drawings up to date as soon as you can just in case any future issues arise.
It sounds like you're dealing with a bit of a challenge there! For the Cutler Hammer WPONIDNA modules, you're right that they typically don't have manual switches for node addressing. You'll likely need to use the DeviceNet configuration software, such as RSNetWorx for DeviceNet or potentially even EDS files compatible with your version of software. As for the end-of-line resistors, it's usually a good practice to have a 120-ohm resistor at both ends of the DeviceNet trunk to ensure proper signal termination. Double-check the specific documentation for your modules if you can find it, but that’s the standard setup. Good luck with the cut-over!
Hey there! It sounds like you're navigating quite a complex setup. You're correct that the older Cutler Hammer WPONIDNA modules typically don't have physical switches for node addressing, so you'll most likely need software to configure them. Eaton's DeviceNet protocol works well with the C441, so you can try using that along with EDS files for the specific modules you have. For end-of-line termination, standard practice is to use a 121-ohm resistor across the last two nodes in your daisy chain, but double-check the manual or EDS documentation for any specific requirements with those older models. Good luck with the cut-over!
Hey there! It sounds like you're tackling quite the project! For configuring the node addresses on your Cutler Hammer WPONIDNA modules, you’ll likely need to use something like RSNetWorx for DeviceNet or even the older version of EDS files specific to your modules, which can help in recognizing and managing the nodes without physical switches. As for the end-of-line resistor, typically a 120-ohm resistor is used to terminate the DeviceNet network at either end of your daisy chain—just ensure you've got one at either end for signal integrity. Best of luck with your cut-over, and don’t hesitate to reach out if you hit any snags!
Hey there! It sounds like you're tackling quite a project with those legacy modules! For the Node address configuration, you’re correct that the older Cutler Hammer modules typically don’t use physical switches. Instead, you'll likely need to use a DeviceNet configuration tool, and many folks recommend using the RSNetWorx software for configuration, as it will allow you to set the addresses digitally. As for the end-of-line resistors, making sure you have 120-ohm resistors at both ends of the DeviceNet network is common practice to ensure proper communication. Good luck with the cut-over, and let us know how it goes!
