Update:
After testing several options and some help of B&R support, this is the conclusion:
-
Fully automatic configuration of the T50 (without the need of the operator to even “touch” the hardware) by only connecting to a PLC is not possible as @tommi.piiparinen already assumed.
-
Although we can enable TFTP on our PLC (PPC50 in this case) to which our T50 is connected, it is not possible to use TFTP as update server type on the T50, which is the default setting:
TFTP is only used internally on the C50 but can not be used by an external client. Also the option “Get update server from DHCP server” must be deactivated because the DHCP server on any B&R PLC using Automation Runtime can not provide the necessary update server information (this is still a selectable option due to compatibility reasons). -
In any case an operator has to manually trigger the upload on the T50’s service page “Update”.
With our hardware setup (PLC + T50) there are two main options we can use anyway:
“Load Configuration from PLC” (As already described by @tommi.piiparinen)
Prerequisites:
- SNMP must be enabled on the PLC.

Note: With this option, updating the T50’ OS is not possible!
Using FTP as update server with minimal manual T50 settings:
Prerequisites:
- FTP server on the PLC enabled
- FTP user created
- T50 files (config and/or boot logo) stored on the PLC’s FTP server
- FTP user has access to the FTP path where the files are stored
- (SNMP not required in this case)
- On the T50, set the update server type to FTP
- Deactivate the option “Get update server from DHCP server”
- Enter the FTP server (hostname or IP adress) and the FTP user credentials
- Save the changes
- Press “Update settings / boot logo / system”
The T50 will restart and fetch the configuration from the PLC via FTP (but first, USB is checked!). Summary can be found here: B&R Online Help
Note: With this option, updating the T50’ OS should be also possible!
