 Hello,

AutoGen_8500329

I use an electronic scale to connect to the s7-1200. The Chinese manufacturer told me that the address of DATA_ADDR is 0000, but I see that what is written in the S7-1200 manual is completely different from what the manufacturer wrote, so I would like to ask how to solve it, thank you

Then I am a student, and I just started to touch this thing recently, so I try to explain it in detail when explaining, thank you~

 clear confirmation that Modbus RTU protocol is used with weigh device is highly required. Documentation snippets of weigh device and Modbus RTU protocol description will be helpful to confirm.
