RPi Modbus TCP to SQL Logger

Hello, I work at a controls company and we have the need for a simple Modbus TCP to SQL data logger that has a web dashboard to allow simple date/time/location queries run against the database and to allow the results to be exported to a .csv file and to view results on a web page. We would like to have the application run on a Raspberry Pi. The data we want to capture would come from multiple PLC's ([login to view URL] P1-540's) and would be grouped by PLC (location). Each PLC generates a set of data that includes Strings and Integers (names and values of items being recorded as a set). Essentially, I want to be able to go to a web page, select a location, date and time and export the results to my computer as a .csv file. I've attached a sample .csv file
