My self also want to Read Energy values which are in Long Real from PAC3200 for S7 400 PLC. Can you please send me with example of using Arrays as I never used Arrays. I don't know how to declare and call them for converting Lreal to Real. Please help.

Hi Piotr.M,

I have a question about the function FC0 -- PAC3200_ENERGY_FEEDBACK.

I  am curious about behaviour in case of overflow? Which behavior is supposed to be if input Real64 number will be greater than number that can be represented in 32bit DINT? Thank you.

- PAC3200 Energy Meter conversion Function which converts LReal to DInt in kWh and Int in Wh which are convenient to display on HMI/SCADA
