The Problem can occur by updating the ctrlX Core with a new image. That requires a update of the ctrlX DRIVE Firmware. If this is not done you will get this error.

The updates of the drive-related firmware files is operated the ctrlX DRIVE Engineering. Perspectivley the handling with the fwa file will rolled out soon. So far the update is covered by ibf files. 

For example the
FWB XD1 ACA ...contains the Axis-controller FW-parts and
FWB XD1 COM ... covers the communication part.

DriveX (without ctrlX Core)
The update needs to be done in a certain order ... 1st ACA , 2nd Com.

DrivePlus with ctrlX Core
Update 1st ACA FW and 2nd ctrlX CORE image (the core image covers the Com internally).

Consider:
- ECAT Communication needs to loaded/created (based on the related ctrlX-IO Engineering). 
  Remember to activate EoE within the ctrlX IO Eng. to be able to reach the drives with ctrlX DRIVE Eng. afterwards.

Note:
- to avoid incompatibility problems regarding the update/downdate of ACA versions (not all version support that handling) -> contact ctrlX DRIVE or ctrlX CORE support before performing.
