Dear experts: The ESD system of the benzene hydrogenation unit at my company is controlled by a GE PLC, with a SQL database for storing historical data. There is a problem now: historical trends can only be viewed for a period of one week. How can this time frame be extended? I hope the experts can give me some advice.

You can also inquire by phone with the system supplier
