I want to build a system with two robots.When I use the button"System Builder",I can not find the item of “I/O control”.

It is very strange!Would somebody know why?And if I do not have this item ,what is the result?My software is “RobotStudio\_School\_Edition\_5.11”.Thank you very much!

I recommed that you use “Create System From Layout” instead of the “System Builder”.
