Devices and networks in TIA shows a red cross on the drive in online view. Why?
There is an error with the communication setting between the drive and PLC. This could be caused by:
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.

What safety category are the drive safety functions rated to?
SIL2, Cat.3/PL d
In an emergency stop state I disable my line module at the same time as the drives. Is this the best/safest way?
No. The line module should be disabled when all axes have stopped moving. This allows for the line module to regenerate any excess energy that is produced by the motors stopping. A typical example would be to use a delayed safety contact to disable the module after the SS1 delay time has expired.
I have a flashing green COM light on my Control Unit. What does this mean?
Communication from a master device is partially or yet to be fully established. Therefore, cyclic communication is not possible.
