Hi experts ,

I am trying to establish communication with a device over Modbus TCP i have a create project with a MB_Client instruction and set variables accordingly .

MB_MODE = 0  (0=READ , 1=WRITE)

MB_DATA_ADDR = 401017 (adress from which one I want to start the read out)

MB_DATA_LEN = 16 (sixteen registers I want read )

MB_DATA_PTR= array of 0...15 Words (sixteen words in total)

Status of a block shows 7005-7006 but it will never transfer any data eventually jumps to 8383 .

I am attaching screenshot of a DB and OB1 , any hint advice will be much appreciated .

Regards
