I have an excel application that uses RSlinx OEM to pull data from the PLC.
If you pull too much, too fast, it can crash excel.
There is a little bit of coding that has to be done as well in the excel environment.
I already had OEM, so this was a program that didn't cost the company anything. If you don't have OEM, I would recommend using a different method. Soon as I can figure out Kepware, I will dump this excel and go with Kepware.
