What could be causing a return value of 8090 for DPRD_DAT/DPWR_DAT?
The hardware ID may be incorrect on the LADDR input. The required ID is the one used by the telegram - not the ID of the drive. For Startdrive, this can be found in the device view by going to Properties > General > Telegram configuration > [device name] > Start address. For drives not configured with Startdive, this can be found in the device view byhighlighting the row of the telemgra in Device overview, then navigate to Properties > General > Hardware identifier.
Getting Online
Devices and networks in TIA shows a red cross on the drive in online view. Why?

- Telegrams in the PLC and drive are not configured in the same order.
