Summary:
The new Koyonet 205 PLCs have a new CPU (model 260). This CPU has extra memory bits. Our Koyonet driver with koyonet205 protocol doesn't let us declare bits higher than 1777(octal addressing). How do we address memory bits with addresses higher than 1777(octal addressing).  

Solution:
Change the protocol to koyonet405. On doing so, you can declare bits up to 3777 (octal addressing). It is strongly advised to bench test the address mapping.
