It would be easiest if you were to connect an 1761-NET-ENI module to the serial port of the SLC, connect the ENI Ethernet port to the computer.
Then you would need some type of OPC server installed onto the computer, a database like SQL Express, and program that can read from the OPC server and write that data to the SQL database. I can't recommend one as we have one developed in house that does that for us so I don't have the experience in others to recomend one. I believe AB sells something...
You would need logic in the PLC to trigger data collection to fit your needs, then you would need some type of front-end on the database to generate the reports/info.
