I’m writing the item path for coils directly on the designer like for example [MyDevice]C50 but I’m not getting any value from it, I have this converter where the value of the Koyo PLC can be converted from Koyo to Modbus values  
how can I write the equivalent of the C50 in modbus like for example C50 is equivalent to 3113 in modbus, do i just write it like [MyDevice]C3113?

That is correct, it would be C and then the coil that you would like to read. So, just like your example of  
[MyDevice]C3113.

Check out the Modbus Specific Addressing section of our user manual for more information
