c550 controllerwith i550 cabinet
Short-term measures, recommendations, evaluation:
All drives, with the exception of the i550 cabinet running FW 6.5 or V7.5, should be connected to EtherCAT. The update can then be performed via a new, empty PLC project for the controller (the project contains only the EtherCAT configuration).
All i550 cabinets running V6.5 or V7.5 must be updated manually using the EASY Firmware Loader and a USB connection.
Alternatively, update only one i550 cabinet at a time via the controller.
