With release RM21.07 we introduce the new feature "Easy service access". You will find this option under "Users & Permissions".
This option should be set before you send the ctrlX CORE back to the Bosch Rexroth Service for troubleshooting or repair.
If this option is clicked, you allow the Bosch Rexroth Service to create an administrator user on the ctrlX CORE to be able to connect the device. The service can then also the debug, perform backup of system data if necessary.
The protection against anyone other than the Bosch Rexroth Service creating an user takes place via a digital signature, which only Bosch Rexroth Service can create.
If this option is not clicked, the Bosch Rexroth Service will not be able to connect the ctrlX CORE. They can then only perform an hardware test and may not be able to repair the device or solve the problem you have.
