Any ideas on the best way to record 24-7 from 10 inputs. Using the 4103 Eurotherm Chessell Chart Recorder with 100 mm Graphics Unit - Ethernet Option - which works - but we just want the data to store in text file or even into columns in Excel.

Consider using an opc server and iconics trendworks. "www.iconics.com":http://www.iconics.com

Since it's talking Modbus TCP, you'd probably be well off to use an OPC server. OPC can poll the data at a specified refresh rate and insert it into sequential cells of an Excel sheet. I've got a system over ethernet logging 24 values 5 times a second. So once per minute should be absolutely no problem.
