The Fanuc R-J3iC was the predecessor to the Fanuc R-30iA controller and is the same controller for most purposes.

The Fanuc R-30iA controller uses advanced technology packed in a proven, reliable, and efficient design. Process capability and open architecture features provide intelligence to improve application and motion performance while simplifying system integration. The Fanuc R-30iA controller incorporates Fanuc Robotics unique “Plug-In Options” concept, which gives flexibility for application-specific configurations while maintaining a commonality for all users of the system. 

The R-30iA controller runs on FANUC operating system, which allows for faster start-ups, higher data security, and ease of use. Advanced communication allows for simple down and upload of robot programs. Additional communication includes: built-in Ethernet, Fanuc I/O-link, and optional Fieldbus (PROFIBUS~DEVICENET~CCLINK). Advanced, I/O features, allow the robot to communicate and control the external end of arm tooling, grippers, and devices. I/O is also used for communicating with external machines such as CNC for loading and unloading parts. The controller offers various programming possibilities such as the standard TPE (Teach pendant editor) way of programming, advanced offline programming options such as using ROBOGUIDE, or KAREL. The R-30iA controller offers FANUC iPendant, an intelligent teach pendant, as an option. Touch screen is also an available option. Additional controller options include DCS Dual Check Safety, Collision Guard, iRVision, and EtherNetIP, to name a few.
