I am working on building a website that will allow a user to view the data real-time from multiple PLC devices and show a graph of previous data for each device up to 24 hours.
I think the best way to do this would be to have a table1 that contains the real-time data from each device and the data from that table is logged into a table created for each respective PLC device.
As an example:
Table1 contains the device name, and the currentspeed of the device.
device1 table contains device name and speedhistory of the device.
I am wanting to take the data obtained from Table1 and log it into device1 as a new record to hold the historical speed data to represent in a graph on the webpage. What is the best way to do this?
