Hello stakow, Jay. give a few more important information. All the values which you want to use (line 36..) are in Wh, VAh, varh. Maybe is this application-example helpful for you: Example SM 1238 AI energymeter

Are you sure that the energy counters are being reset? You need the latest firmware to be able to correctly reset the energy counters. This is version V02.00.02. You can download it here: https://support.industry.siemens.com/cs/document/109760770/firmware-update-for-sm-1238-energy-meter-480-vac?dti=0&lc=en-WW There is a new version of the manual that has a better description of how to reset the energy counters. See pages 47-53. Also see page 42 for when the energy counters are reset automatically. https://support.industry.siemens.com/cs/document/109483435/simatic-s7-1200-sm-1238-energy-meter-480vac-(6es7238-5xa32-0xb0)?dti=0&lc=en-WW Why is your Power_factor_L1 very small (0.019)? The L2 and L3 power factors seem reasonable. Is the scaling correct for the current and voltage in the configuration? Larry |
