Regards, Kaulquappe Dear Sarfraz, As explained above, unfortunately you must use zXX21_11_1SI_MODBUS. I recommend you to read themanualagain, especially Modbus Master section. It explains the DB structure in depth. You can try modifying your present DB with 'write' function code to see if it works. Best regards, Andrew
