<div class="markdown_content"><p>Hi everyone,</p> <p>I would appreciate your help with a problem I've been working on for a few days but haven't been able to resolve.</p> <p>I am reading data from a Siemens PAC3220 energy analyzer using Modbus with Wago-8202. However, the device's energy indices are given as doubles. Since a double variable is 64-bit, it is not possible to read it directly. I have been struggling for days, I have written many conversion functions but I have not been able to get results. I would appreciate your help.</p> <p>I read 4 word variables and processed them. I am converting them according to IEEE-754, but I can't seem to read the correct data. I would appreciate your help.</p></div>
