Good morning Can anyone kindly help me? I have the PAC 3200 and 3220 in the industry and I also need to read the values ​​"Total active energy Import Tariff 1", but I have already made several attempts and read several forums, but without success. I would like to know how I insert addresses into MB_Client and how to structure it.  The other values ​​such as voltage, current, power, I was able to read normally, my problem is in active energy tariff 1. Thank you very much in advance!

Split from Read out data from many PAC devices .

the energy data is stored as "double", a 64bit real. If you are using a s7-1200 you will struggle to get it displayed since the PLC "does not support 64 bit tags"

If you are on a PLC that support 64bit you should be able to just throw the 4 relevant (offset 801) registers together.

Keep in mind that you cannot just read the whole mapping (from voltage to energy) using MB_CLIENT, since a maximum number of 125 registers can be read at once.

I'm using a 1517 CPU, but I can't read the active energy tariff values, which are at offset 801. Can you explain to me in a more didactic way how to insert the addresses and how to structure the data block to be able to read these variables? The data type would be:

REAL

DWORD

INT

DINT

LREAL

THANKS
