Hi,
The B&R EX290 is a X2X communication module and not the PLC that contains the software.
You will need the AutomationStudio software and the source code for the project in order to make any changes or troubleshoot the code. Depending on the PLC type you will need either a serial or ethernet cable to connect to your PC. B&R offers a demo version of Automation Studio that allows you 30 days to work with the software. Then you will need to purchase the license.
