energy counter formats using Modbus TCP

Brynjar

I'm reading values from PAC3200 through Profibus DP into a DB. All works fine, but the energy import/export have a "double-float" format in PAC3200. How can I read these values correct into the Receive-DB?

Hello,

The SENTRON PAC3200 has two available energy counter formats, double and float.
Look to the GSD-file in simatic hw-config, e.g. there you can find the energy counter import tariff 1 (D) and energy counter import tariff 1 (F). (D) = double format 64bit, and (F) = float format 32bit.
