Hi Kaulquappe,
    

                       I consider it is for start & end address for slave. ok i will make it as" 0" for both adr_high

& adr_low, after that it will read data from slave  or i have to change any thing??

so in sample project  why they mention as  adr_high & adr_low in Source DB how it will work.

Hi,

      I make it both add_high & add_low as 0  but now also show same error  0e62

I have attached error in below file

Please help me
