This is less a PLC question than it should be. I need to get some information out of a CLogix 5000. I need to track the amount of time a machine runs without a Thermal Oxidizer(track pollution control. This needs to be accurate to a tee, as it will be reported to the WDNR. I was thinking of just monitoring the run status bit for the machine, and the Thermal Ox Running bit in the PLC, and use them to trigger a timer value. I thought I could do this all in Excel, but the problem there is that if I lose my connection to the PLC, the values in excel stay in their last state. The problem with doing the calculations in the PLC is the fear of a program download contaminating the data. How would you guys do something like this? I'm very green at this, and all suggestions are welcome. Thank in advance.
