Reading KWH-active energy in M580 using I/O scanning

[Salah_Mohamed]

Active energy for PM5100  is INT64  and M580  doesn't support INT64  ,How can I solve that issue ?   

I've now array of two real variables ,I think needs to sum those two variable ?

The M580 or M340 do not support 64-bit data types.  There is a posting by Michael Wisesa  https://community.se.com/t5/Modicon-PAC-Forum/64-bit-Float-Modbus-Register/m-p/417304#M751 that may help.

The other is another related topic that may add ideas.
