text: <s>[INST] Power Flex 40 - Device Net Adapter Problem The MOD LED is blinking red. The drive is not used in Multi Drive mode.The drive was working before around 100 hours then not used just staying in the cabinet as spare. HMI was sending speed and Run/Stop parameters, but no motor was connected to it. Wiring of the Device Net is ok.There was no error on the drive. I cycled power and nothing changed. I also reset to default values and nothing happened. I also got some warnings when resolving device mismatch. I never saw this message before. I attached a screen cut width the warning.The module was moved to another Power flex and still having the problem width the module. If I browse the network width RsNetWorks, then the module is shoved active, but on the device net scanner I have Error 83 for that node address. Flashing the adapter with the latest firmware release, I saw is not possible on field.- My question is what I could do to recover that drive- And second what could happened, in order that I prevent it in the future. [/INST] Hi enguson, and welcome to the Forum ! :smileyhappy: First, the MOD led... as you may already have seen in the User Manual, this is the meaning:The adapter has failed the firmware test, connected drive is faulted, or a drive is missing in Multi-Drive mode. Excluding second and third possibilities, as per your indication, only a firmware problem remains.Here some tests, also from troubleshooting chapter:If cycling power does not correct the problem, the parameter settings may have been corrupted. Reset defaults and reconfigure the module. If resetting defaults does not correct the problem, flash the adapter with the latest firmware release. The firmware of the communication adapter *can* be upgraded in the field, HERE the website with the firmware and instructions. About the scanner error 83...Slave device is returning error responses when module attempts to communicate with it (node number alternately flashes).Check accuracy of scan list table entry. Check slave device configuration. Hope this helps… - fuzzy logic \\n </s>
