Hello everyone, I am seeking advice on replacing a PowerFlex 40 drive on a DeviceNet network. The new drive I have purchased has a revision mismatch. Unfortunately, I am unable to change the revision in RSLogix5000 or RSNetworx as not all drives on DeviceNet are showing up. Can anyone advise on what steps I should take in this situation? Your assistance is greatly appreciated. Thank you.
Which specific Devicenet scanner model do you currently employ?
Whenever I encountered a firmware revision mismatch, I would simply go online using RSNetworx to perform an update, which effectively resolved the issue.
For older scanners, accessing the PLC in program mode is necessary for downloading the RS network configuration after making changes. However, newer models may allow for online editing of scan lists. This feature is especially beneficial for users who need to modify network settings on the go.
Good morning! I am using a 1756-DNB DeviceNet card for my device.
I can utilize RSNetworx to make updates and perform uploads/downloads to a new drive. However, the MOD light on the drive is continuously flashing and is accompanied by the error code F071.
Hi there! It sounds like a frustrating predicament with the revision mismatch on your DeviceNet network. First, I'd recommend double-checking the firmware version on all devices connected to the network to ensure they’re compatible with your new PowerFlex 40 drive. If you're still not seeing all drives in RSLogix5000 or RSNetworx, it might help to cycle the power on your network devices and ensure that termination resistors are properly in place. Additionally, try using the DeviceNet scanner’s online tools to see if it can recognize the new drive; sometimes a simple configuration refresh can do the trick. If the issue persists, checking the network configuration settings to confirm they match can also be a good bet. Hope you get it sorted out soon!
It sounds frustrating to deal with the revision mismatch and the visibility issue on DeviceNet! First, I’d recommend double-checking the firmware version of all your existing drives to ensure they are compatible with the new PowerFlex 40 drive you’ve purchased. If some drives aren't appearing in RSNetworx, try cycling the power to the DeviceNet network and running a network scan to see if that helps bring them back online. Also, make sure that your device definitions in RSNetworx are up to date; sometimes, outdated definitions can lead to these kinds of issues. If the problem persists, consider a temporary workaround by using a different gateway or device to facilitate communication until you can resolve the revision conflict. Good luck!
