Hi everyone Before I start, I just wanted to let you know that I’m not 100% familiar with the RobotStudio environment and that I’m still new in that domain (Sorry in advance if my problem seems silly). So I have an IRC5 controller with the DeviceNet Master/Slave option, but I also need to set up a connection between my controller and a PLC (with Sysmac Studio). In the Configuration - I/O system tab I can see in the industrial network section that I have the DeviceNet but I’m pretty sure I also need the Ethernet/IP anybus option. So my questions are: -Do I really need this option for my application? -If yes, do I need a license key like, for instance, the multitasking option? Thank you ---

Look in the backinfo folder for the backinfo.txt file, it will list your options. If you don’t have ethernet/IP option then you will need to buy it and they should give you a new keystring.
