I need a simple program to read one set of registers in a Sentron PAC3200 meter 4 times per day and write them to a data file or a spreadsheet.
I have the meter installed and the free program Powerconfig 3.8 runs on my Windows 8.1 PC, but it only reads in real time and doesn't log. I need a log file that will run for months until I need to do some math with it.
I tried the AGG Modbus TCP/IP Data Logger software, and was helped to get it working. As demonstrated to me by the tech, it offered what I wanted. The trouble was when I paid for the Standard version $76 US yesterday, all of the Modules were missing and greyed out, so it now doesn't work. I requested a refund and am looking at new solutions.
