text: <s>[INST] Communtcation Error on Powerflex 40 Drive with DeviceNet I have a DeviceNet MCC and a Poweflex 40 Drive in a tub. I am having very random Faults they say Fault 71 Adaptor Net Loss. The Lights on the communication card are flashing Green on the Mod light and the Net A light. It does this off and on every few days. If you turn the power off to the drive it resets it and the lights all go solid green and the drive starts to function correctly. Its goes from device net to a scanner to ethernet. Any Ideas ?? [/INST] Check to see how many Dnet nodes you have on the link and also how fast is your RPI (update time) set for the drive. Also, you can configure the drive to not fault or alarm on net loss. \\n </s>
