OK, how do I say this without "advertising"? I work for a company that specializes in protocol conversion. We don't currently have a CC Link interface, but we do have an optimized software architecture that allows us to produce drivers very quickly--in about 10% of the time its traditionally taken.
We do however have a Profibus DP interface. I would want to know more details of what you are trying to do to get an idea of the scope. Rather than implement every CC Link function, we typically focus on just what a customer requires for his project (thus allowing us to test and validate those specific functions...)
