ICC stands for Industrial Communication Creator; it is the unified tool by port for creating projects of any of the supported protocols. For the CC Link IE TSN stack, it helps creating a project configuration and the CSP+ device description file. For the Remote Station SDK, it is also able to create the local object dictionary for the CANopen support.
Note: It is possible (but not recommended) to create project configurations manually. For the CSP+ files, other tools may be used either on their own or together with the ICC. Creating an object dictionary without the ICC is not recommended.
